The Human Skin

The human skin is considered as the largest organ of the integumentary system and one of the most important parts of the body. It is made up of several layers of epithelial tissues which guard the underlying muscles and organs of the body. The skin plays the most important role in terms of the protection through pathogens, sensation, insulation and regulation of body temperature . It also functions in the synthesis of Vitamin B and D.

The melanocytes provide the skin with pigmentation or melanin which absorbs the ultraviolet radiation in sunlight. Melanin also contains DNA repair enzymes which help in reversing the UV damage and skin cancer. Malignant melanoma is one effect of UV light which is considered invasive and deadly. Pigmentation varies among races thus leading to classification of people in terms of skin color.

The outer portion of the skin, the epidermis, is composed of stratified squamous epithelial tissue. Its outermost layer (stratum corneum) consists of hardened dead cells that are constantly being sloughed off. Active cell division in the deeper layers of the epidermis produces new cells that pushed outward and take the place of those that are lost. Beneath the epidermis is the dermis, a layer composed chiefly of connective tissue. Blood vessels penetrate into the dermis and not into the epidermis. Sweat glands are embedded in the deeper layers of the dermis, and their ducts push outward through both dermis and epidermis to open onto the surface through sweat pores. Both glands and ducts are derived from the epidermis; they form initially as folds of the epidermis that push downward into the connective tissue of the dermis.

Hairs, and the inner layer of the hair follicles in which they are encased, are also from the epidermis and also develop as folds into the dermis. When the hair follicle is fully developed, the bulbous base of the follicle and the hair root lie deep in the dermis; the shaft of the hair extends at a slant from the root to the surface of the skin and beyond. A small muscle runs diagonally in the upper portion of the dermis to the hair follicle near its lower end; when the muscle contracts, it pulls the hair erect. One or more sebaceous (oil) glands empty into the hair follicle. Numerous nerves penetrate into the dermis and few even penetrate into the epidermis. Among them are nerves o the hair muscle, sweat glands, and blood vessels, and also nerves terminating in the sensory structure for touch, temperature, and pain. Beneath the dermis, but not delimited from it, is a subcutaneous layer, which is not considered as the part of the skin itself. This is a layer of very loose connective tissue, usually with abundant fat cells. This is the layer that binds the skin from the body. The extent and form of its development determine the amount of possible skin movement.

Three Receptors of the Skin and the Senses They Mediate:

  1. FREE NERVE ENDING (pain). Some of the skin receptors are the unmyelinated terminal branches of neurons.
  2. NERVE PLEXUS AROUND THE HAIR (hair). Nets of nerve fibers surrounding the bases; these are stimulated by the slightest displacement of the tiny hairs present on most parts of the body.
  3. PACINIAN CORPUSCLE (deep pressure). Skin receptors have nerve endings surrounded by a specialized capsule of connective tissue cells.

The sensory receptors of the skin are concerned with touch, pressure, heat, cold, and pain. Unlike the receptors in the skin, which function in receiving information from the outside environment, some other receptors widely dispersed over the body function primarily in receiving information about the condition of the body itself.

DNA Tests are used for paternity and legal purposes.

DNA Tests are used for paternity and legal purposes.

DNA Testing

The patterns of segments in living cells of the hair are being used as sources of genetic material to create the genetic fingerprint of an individual. Each one of us has our own unique genetic information or deoxyribonucleic acid (DNA) which can be separated and sorted into segments of different lengths. The resultant pattern looks like the bar code in the supermarket. Documented patterns are stored and used in identifying criminals, victims or for paternity test.

The skin is the largest organ of the body. The skin, including nails, hair, and sweat glands, is sometimes called the integumentary system. Skin has two layers: the epidermis and the dermis. Subcutaneous tissue provide protection for the skin.

The epidermis forms the outermost layer of the skin. It serves as a barrier between the outside world and the inner tissues of the body. The outer portion of the epidermis consists of tough, dead cells that prevent bacteria, chemicals, and other harmful substances from entering the body. It also protects the body's inner tissues from the harsh rays of the sun and prevents the loss of water from these tissues.

The dermis is the lower layer of the skin. The dermis helps keep the temperature of the body within its normal range. The body produces tremendous amounts of heat as it uses food. Some of this heat escapes from the body through the blood vessels in the dermis. When the body needs to retain heat, these blood vessels narrow and so limit heat loss. When the body needs to give off heat, the blood vessels in the dermis expand and so increase heat loss. The sweat glands, which come from the epidermis, also help control body temperature.

Skin is very important it is our shield. The impications in business is we can create a product to help the skin of an individual make glow and a have a beautiful skin esp. the actors and actresses so that they see their beauty behind and inside of the camera in the public.

Krischarm David BSBA1-1 on January 15, 2016:

The ski is largest organ of the body, and together with its appendage hair, nails, cutaneous glands its makes up the integumentary system.

The skin keeps microorganisms and other foreign materials from entering the body. Since the outermost layer is waterproof, the skin also keeps the body from dying out.

The skin is also helps keep heat in when the body is too cool. Blood vessels kn the skin narrow slightly, reducing the supply of blood to skin capillaries. The body also sweats less. In this manner, less heat is lost from the body. If the body is cold, it can produceheat by muscles tension and shivering. These maintaining of constant temperature is eg. Of homeostasis.

The relevant this skin i can produce or i can make the product to protecting our skin .. Like lotion to protecting our skin to the heat of the sun.

Skin is our largest organ and plays a very important role. Our skin is very important because it covers and protects everything inside of our body. Without skin, people's muscles, bones, and organs would be hanging out all over the place. Since our skin plays such an important role in protecting our body, we should keep it as healthy as we can. This will help us keep from getting sick or having damage to our bones, muscles, and internal organs.

The skin is the largest organ of the Integumentary System. The skin is also the most sensitive part in our body. The skin cover up our body which protects our internal organs even our muscle, it protects us from different kinds of bacteria and germs. For short it is the shield of our body's internal organs which stops different kinds of bacteria and germs from entering our body to infect us. That is why taking care of our skin and being clean always can lessen the chance of us getting sick and safe from different diseases.

A drug is any substance other than food, that when inhaled, injected, consumed or absorbed via a patch on the skin causes a physiological change in the body.

In pharmacology, a pharmaceutical drug or medicine, is a chemical substance used to treat, cure, prevent, diagnose a disease or promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis.Pharmaceutical drugs may be used for a limited duration, or on a regular basis for chronic disorders.

For me the function of the Integumentary System is to protect us. Without having skin, our organs would fall out, the integumentary system also keeps our temperature in check, and keeps us from dehydration and a lot more. It is very important, as in very important. For protection, support, and movement. So we should take care of it by maintaining proper hygiene of our body.

Drugs have a great impact on the lives of humans. They have the power to alter their lives and the world around them. They can destroy people and their future. Still some hail them as miraculous cure or savior for their hardships in life, until too late, they realized that they are not. So as an accountancy student we have to make an intelligent decision. The decision we make has consequences to ourselves, our family, and society. Staying away from drugs is an important responsibility we have to fulfill.

The skin is very important because it covers the entire body system. And because of the skin the appearance we can feel everything around us even if we do not see the surroundings. Because of the skin we do not like zombies. And also the skin secretes waste in the form of water which is called sweat, and is it good for our body to secrete those waste.

Reyes, Ma. Isabel C. BSBA1-1 on January 15, 2016:

The Integumentary system is an organ that consist of the skin, its derivatives (sweat and oil glands), nails and hair. The basic function of the skin is protection. The skin consists of epidermis and dermis. Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature. In order to do these things, the integumentary system works with all the other systems of your body, each of which has a role to play in maintaining the internal conditions that a human body needs to function properly.

The human skin, this was the outer covering of the body. In humans, it is the largest organ of the integumentary system. Human skin is similar to that of most other mammals, except that it is not protected by a fur. Fur is used in reference to the hair of animals, usually mammals, particularly those with extensive body hair coverage. Though nearly all human skin is covered with hair follicles, it can appear hairless. Imagine if organisms had no skin? It's creepy and maybe we don't function right. Many people have a highly concern when it comes to skin because having beautiful skin make us attractive. As an accountant it is better to have an attractive skin so they are be more presentable in the eye of everyone, not just for the clients but for their co-workers, boss, managers and etc.

Now a days many people are concern to their skin specially in the field of the industry of showbuzz and If you have the necessary training, certifications and licenses, you may wish to set up a home salon and spa center. You can't start working on people without some training. For example, masseurs go to schools of massage therapy. If you've learned skincare skills, then you must supply your business with all of the necessary products before you can run a home spa.

Mariella Dela paz B S-Psy on January 15, 2016:

Without this I think We are all exposed in all kinds of deseases. The skin is an organ of protection. The primary function of the skin is to act as a barrier. The skin provides protection from: mechanical impacts and pressure, variations in temperature, micro-organisms, radiation and chemicals. The skin is an organ of regulation. The skin regulates several aspects of physiology, including: body temperature via sweat and hair, and changes in peripheral circulation and fluid balance via sweat. It also acts as a reservoir for the synthesis of Vitamin D. The skin is an organ of sensation. The skin contains an extensive network of nerve cells that detect and relay changes in the environment. There are separate receptors for heat, cold, touch, and pain. Damage to these nerve cells is known as neuropathy, which results in a loss of sensation in the affected areas. Patients with neuropathy may not feel pain when they suffer injury, increasing the risk of severe wounding or the worsening of an existing wound.

Castro, Theanna Giomarie M. BSA1-3 on January 15, 2016:

The skin, or integumentary system, is the body's largest organ. It protects us from the outside world, and is our first defense against bacteria, viruses and other pathogens. Our skin also helps regulate body temperature and eliminate waste through perspiration. In addition to skin, the integumentary system includes hair and nails. The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold. It is important because it offers protection, a barrier to water, absorbs things, synthesizes chemicals, it regulates your body temperature, and last, it transfers information. Our skin health is important not only for our appearance, but more importantly because our skin performs so many essential tasks for our body. Our skin protects our body from the many viruses and bacteria you are exposed to daily. It also protects us from the sun's rays - specifically ultraviolet light - that can damage cells. Healthy skin produces vitamin D when exposed to the sun, and vitamin D is important for many body functions. Having healthy skin also helps your body keep its temperature at a constant level. Healthy skin also helps you react better to important changes around you by feeling pain or pressure.

Everyone know that the skin is the largest organ of the body. But it also performs various functions for the body.

It serves as a protection for the organs inside the body from the pathogens and other substances to enter the body.

It is also a barrier to the water. It absorbs selectively the oily substances that are small enough to penetrate between the cells.

The skin also regulates our body's temperature. And the nerves in the skin respond to different stimuli by passing those information to the central nervous system.

Diseree Olyssa Salas BSBA 1-1 on January 14, 2016:

The characteristic features of skin change from the time of birth to old age. In infants and children it is velvety, dry, soft, and largely free of wrinkles and blemishes. Children younger than two years sweat poorly and irregularly; their sebaceous glands function minimally. At adolescence hair becomes longer, thicker, and more pigmented, particularly in the scalp, axillae, pubic eminence, and the male face.

It was discussed that our skin has three main functions: protection, regulation, and sensation. Our skin can be a good reflection of the overall health of our body. Our skin has two layers – the epidermis and the dermis. The epidermis is the outer layer of our skin while the dermis is the inner layer of our skin which is 15-30 times thicker than the epidermis. Aside from a good reflection, skin is our protection. If we are going to relate this in the real situation today, human beings need protection. There is no safe place in this world so all of us need protection.

The human integumentary system is an external body covering, but also much more. It protects, nourishes, insulates, and cushions. It is absolutely essential to life. Without it, an individual would be

attacked immediately by bacteria and die from heat and water loss. The integumentary system is composed

primarily of the skin and accessory structures. Those structures include hair, nails, and certain exocrine glands (glands that have ducts or tubes that carry their secretions to the surface of the skin or into body cavities for elimination).

Our skin covers and protects everything inside your body. Without skin, people's muscles, bones, and organs would be hanging out all over the place. Skin holds everything together. It also protects our bodies, helps keep our bodies at just the right temperature and allows us to have the sense of touch. Skin is essential in many ways. It forms a barrier that prevents harmful substances and microorganisms from entering the body. It protects body tissues against injury. It also controls the loss of life-sustaining fluids like blood and water, helps regulate body temperature through perspiration (sweating), and protects from the sun's damaging ultraviolet rays. Without the nerve cells in skin, people couldn't feel warmth, cold, or other sensations. Accountant is like skin.

Skin is our largest organ and plays a very important role as our first level of defense against a host of environmental aggressors. A multitasker like no other, our skin has many important functions, all of which are designed to help keep our bodies working properly. Some of its functions include 1. Our skin is like a Body Guard…it offers protection. One of its most important jobs, our skin provides a barrier to harmful environmental aggressors like germs and UV radiation. Our skin’s acid mantle is very important in preventing bacteria from attacking our skin and causing infection. Even our skin’s ability to “tan” (increased melanin production) is a system designed to protect us from UV radiation. 2. Our skin is like a Raincoat…it’s a barrier to water. Our skin cells need water, yet if the surface of our skin (and the walls of our skin cells themselves) did not have a “waterproofing” effect, all the water in our skin would evaporate and the cells would die. How does it work? The outermost layer of skin (called the stratum corneum) is made up of keratin, which likes oils much more than it likes water. 3. Our skin is like a Sponge…it absorbs things. While the outermost layer of skin is designed to repel water, it can also selectively absorb oily substances that are small enough to penetrate in between the cells. Technically speaking, the keratin creates a semi-permeable membrane. This is why patches of some medications work as a delivery system. 4. Our skin is like a Manufacturing Plant…it synthesizes chemicals. Complex chemical reactions are constantly going on in our skin to keep cells regenerating, repairing damage and even converting sunlight into Vitamin D. 5. Our skin is like a Thermostat…it regulates your body temperature. When we are hot, our skin can cool our entire bodies by sweating and also increasing blood flow, which allows heat to be lost through the skin. In contrast, when we are cold, the diameter of our blood vessels decreases, which reduces blood flow, retaining heat in the body. 6. Our skin is like a Switchboard…it transfers information. Nerves in the skin respond to different stimuli, including touch, pain, pressure and temperature by passing along information to the central nervous system.

Skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. The skin's primary functions are to serve as a barrier to the entry of microbes and viruses, and to prevent water and extracellular fluid loss. Acidic secretions from skin glands also retard the growth of fungi. Melanocytes form a second barrier: protection from the damaging effects of ultraviolet radiation. When a microbe penetrates the skin (or when the skin is breached by a cut) the inflammatory response occurs. In accountancy, accountants serves us the defender of every financial statement he makes. He should maintain the interity of the firm no matter what and commit no errors as much as possible.

The skin, together with its modification such as the hair and nails are the main components of the integumentary system. The skin has a lot of nerve receptors that allow it to respond to pain, changes in temperature and pressure, and touch. It also controls body temperature through the evaporation of sweat. The skin consists of two layers: epidermis and dermis. The epidermis is the thin outer layer and the dermis is the thick inner layer. The skin has glands, too. An example of a gland in the skin is the sebaceous gland or oil glands that secrete oil to prevent hair and skin from drying out.

Our skin is one of the largest organ that helps and protect our body from some chemicals or substances that can lead to some problems or complications like from diseases, bacteria, UV rays, or even physical damages. Without this or even facing some problems involving our skin we cannot face our environment or even the people around us with gratitude or self- esteem.

Integumentary system is impotant because it is the group of tissues that works together to cover or to enclose an organism or one of its parts. The skin is our integumentary system. The skin is largest and the most visible organ especially in humans. Skins role is to regulate one's body temperature. Through sweating, our temperature become regulated. Also, the salt in our skin helps in the evaporation of water and helps in keeping moist. And therefore this topic is very significant and well related to our course, accountancy. Because this taught us to look not only on whats inside of a thing but also to what is visible for us to be able to protect, and prevent complications to arise. This is also related to all the courses because we are all humans who have skin that covers and encloses us. We are all related to the integumentary system.

The human skin is the outer covering of the body. it is the largest organ of the integumentary system and one of the most important parts of the body. Skin plays a key immunity role in protecting the body against pathogens. The skin consists of three layers of tissue: the epidermis, an outermost layer that contains the primary protective structure, the stratum corneum; the dermis, a fibrous layer that supports and strengthens the epidermis; and the subcutis, a subcutaneous layer of fat beneath the dermis that supplies nutrients to the other two layers and that cushions and insulates the body.

Skin interfaces with the environment. It plays as a key immunity role in protecting the body against pathogens and excessive water loss. If we don't give attention or take good care to our skin, it will lead to damaged skin like being dry to oily or worst it will lead to skin cancer. Severely damaged skin will try to heal by forming scar tissue. This is often discolored and depigmented. Skin cancers are cancers that arise from the skin. They are due to the development of abnormal cells that have the ability to invade or spread to other parts of the body.
