You might be surprised to discover some things you did not know about your own body. In fact, you might think some of those amazing things cannot be true. However, through research, everything written in this article is true to the best of this writer's knowledge.
When you get out of bed in the mornings, you are a wee bit taller than you were when you went to bed the night before. That's because pressure is put on your joints during the day while you are up and about. Therefore, the cartilage in your spine is compressed enough to push everything down during the day. The pressure on your spinal disks allows you to return to your full height.
If you do not believe this, there is a simple way to find out if this is true. Measure your height before going to bed at night. Then take your measurement when you get up the next morning.
After people have been dead for a while, their bodies turn into a skeleton. What people might not know is that even living people get a skeleton every ten years. If you are 70 years old, you have had seven skeletons during your lifetime.
About Your Bones
Your bones are stronger than a piece of steel. The strongest and longest bone in the body is your thigh bone that is called the femur. It takes a lot of force to break it because it is so strong that it can support up to 30 times your weight.
According to Mammal Anatomy: An Illustrated Guide, babies are born with 300 bones, but adults have only 206 bones. Why does a tiny baby have almost a hundred more bones than its parents? The answer is not hard to believe. As a person grows, his bones fuse together. So, instead of having two, they become one. By the time a person reaches adulthood, at least 94 bones have fused together with other bones. Therefore, the bones a baby was born with have merged with other bones which causes the decrease.
There are 27 bones in each hand. There are 26 bones in each foot with 33 joints and over 100 muscles, tendons, and ligaments. That means that more than half of the bones in your body are in your hands and feet.
Your Largest Muscles
According to the Library of Congress, your rear end has your largest and strongest muscles. The muscles move your hips and thighs to work against gravity to keep you walking upright when you go uphill and upstairs.
When researchers in Meridia Huron Hospital tested the effect gastric juice has on metal objects, they found that within 24 hours, the stomach acid had reduced razor blades to 63 percent of their original weight.
If your small intestine is uncoiled, it will be four times as long as you are. That's because it is about 18 to 23 feet long.
There is a reason your gut is referred to by scientists as your "second brain." Your gut does more than help you digest your food. Your gut has its own reflexes and senses that work along with your nervous system. That's why people say, "Go with your gut" and "Trust your gut."
When you are hungry, the mixture of fluid and gas moving around in your intestines is what makes your stomach growl.
Babies have more bones in their bodies than adults, but all adults have something that babies don't have. Babies don't have kneecaps. Cartilages gradually turn into bone, and kneecaps begin to develop when the child is between two and six years old. Kneecaps aren't fully developed until the child reaches young adulthood. Look at a baby or a child less than six years old. You will see no kneecaps.
There are no muscles in your fingers even though you can do many things with them. The movement of your fingers is due to tendons and bones, not muscles. There is help from the muscles in the palms of your hands.
Most of the strength of your hand is in the pinkie, your smallest finger. The pinkie helps the other fingers to function.
About Your Ears
Earwax is 50 percent fat that coats the ear and catches dust and debris. Earwax might be annoying and looks gross, but it is actually good for your ears. It keeps the ears healthy. The wax lubricates the ears, cleans them, and protects them from infection.
People blink about 15 to 20 times every minute. Blinking is necessary to keep your eyes moist. A blink is called a "micronap." Researchers at Washington University found that blinking helps sharpen attention and gives the body time to recharge.
Big eyes can be the cause of nearsightedness, known as myopia. That condition causes distant objects to look blurry because light doesn't properly reach the retina.
Dementia manifests itself in a person's eyes. According to a 2019 study published in Neurobiology of Aging, researchers discovered that individuals who are at risk of developing Alzheimer's have greater pupil dilation while performing cognitive tasks.
Not Two Bones
In every other part of your body, muscles connect to bones at both ends. However, your tongue is the only muscle that doesn't join two bones. It is connected to the hyoid bone, which is part of your neck. However, there is nothing on the other side of your tongue.
Your Tongue Print
Fingerprints are not the only things unique about a person. You have a unique tongue print also that is different from anyone else's.
According to a 2016 study by the Thai Moogambigai Dental College, no two tongues are exactly alike. Even twins have different tongue prints.
Like hearing and seeing, taste decreases as a person ages. Taste buds also diminish after sickness, an injury, or after taking some medicines. Women usually experience a decrease in their taste around the age of 50. Men don't experience a change in their taste buds until they are in their 60s.
Humans have a body part that their pets and other animals don't have. Animals don't a chin, but they do have jaws. Take a look at your pets and see that this is true.
Your fingernails and toenails grow faster as you age. A 2010 study at the University of North Carolina compared the growth of fingernails and toenails to studies done 50 to 70 years ago. They found that growth had increased over the decades. Researchers think the reason is because of the rising increase in protein-rich diets.
The American Academy of Dermatology (AAD) says a fingernail takes around six months to grow from base to tip, and toenails can take up to a year to grow that length. The AAD also reported that fingernails grow faster on a person's dominant hand, as well as on the bigger fingers. They also grow faster during the daytime and during the summer months
Your nose has two nostrils, but they do not work at the same time. You breathe through only one nostril at a time.
According to the results published in the journal Mayo Clinic Proceedings in 1977, one nostril takes a break while the other nostril takes over and does all the work. After a few hours, the nostrils switch places. If you think this is unbelievable, test it by putting your finger under your nose and find out that this is absolutely true.
About Your Hair
You Are Hairy
People have just as much hair per square inch as chimpanzees. That much hair is not visible on your body because it is much finer, according to a 2011 paper published in the International Journal of Trichology.
Hair Can Detect Bitter Tastes
Nasal passages and lungs are lined with fine hairs that detect and sweep out impurities. Hair can detect bitter tastes passing through them such as nicotine.
Hair Tracks Your Sleep
Your hair knows when you are asleep and when you are awake. It can track your sleeping patterns. Researchers at Yamaguchi University discovered in 2010, that hair follicles can track the body's clock and knows about a person's sleep and wake cycles. Your hair can detect if you go to bed late or if you get up early.
Hair Helps the Environment
According to environmental engineers at the Missouri University of Science and Technology, dirty hair can be good for the atmosphere because it absorbs the air pollutant ozone. Scalp oils contribute to this.
A person's skin can indicate if a person has high cholesterol that can lead to a heart attack and heart disease. Uneven yellow patches called xanthelasma can appear on the eyelid and around the eyes as a result of overproduction of cholesterol, according to the American Osteopathic College of Dermatology (AOCD).
Your blood makes up 8 to 10 percent of your total body weight. Hematologist and oncologist Daniel Landau, MD, explained that people have about 1.2 to 1.5 gallons of blood in their veins. However, a baby has barely any blood when it is born.
Dr. Landau, says it's typical for babies weighing 5 to 8 pounds to have no more than one cup of blood in their body.
Most people know that the liver grows back to its normal side, even if it is reduced by as much as 75 percent. This can happen within a month, according to the University of Iowa. That's why some people don't mind donating part of their liver, if they are a match.
When you lose weight, the pounds do not disappear in thin air. About 84 percent is converted into carbon dioxide and leaves your body through your lungs, according to the British Medical Journal. The remaining 16 percent is converted to water, which exits your body through sweat, tears, and other bodily fluids.
