Facts about the Human Body

We tend to think that we know our own bodies pretty well. We know how they work and what kinds of changes are occurring every second of the day. But in fact, the human body is a seriously complex and mysterious mechanism that sometimes confuses even the most qualified specialists.Here are some stunningly interesting facts about our body that canimpress anyone.

      1.      For every pound of fat gained, you add seven miles of new blood vessels

New tissue needs blood supply, so your vascular system expands to accommodate it. This means that your heart must work harder to pump blood through the new network, which may reduce oxygenation and nutrient replenishment in other tissues. Your body will break down and reabsorb the unneeded blood vessels from the previous tissue.Our blood vessels are 100,000 miles long and we breathe 50,000 times in a day. Moreover, our body is full of surprises as it can do incredible stuff.

      2.      The brain itself cannot feel pain - It has no pain receptors

Receiving and processing sensory input such as vision, smell, touch, or taste are part of all the complex functions that brain performs. Among these sensory inputs is pain which can come from literally any part of the body. These inputs and signals are interpreted by the brain as “pain” which indicates that something bad is happening.  On top of that, the brain then initiates actions which it determines are required to deal with it. However, the brain itself cannot feel pain because it has no pain receptors. So, if you are experiencing headache, the pain is probably coming from the membranes surrounding the brain, the connective tissue over your skull or the scalp, but not brain.

      3.      You are taller in the morning than in the evening

When you crawl out of the bed in the morning you are at your tallest. On average, you are one half inch taller when you wake up in the morning, thanks to excess fluid between within your spinal discs. While you are sleeping, these fluids replenish. During the day your body has to deal with the stress of standing, so the discs become compressed and the fluid seeps out. This ultimately results in you losing a small amount of extra height.

      4.      The acid in our stomach is strong enough to dissolve razor blades 

The stomach is the organ that digests everything we eat and has to take care of the bacteria and other harmful things that enter it. Scientists experimented on razor blades, disc batteries, and pennies by putting them in simulated gastric juice to find out the best way to deal with them when they are accidentally swallowed. They found that after twenty-four hours the blades weighed 63% of their original weight and became fragile. The disc batteries, however, showed no leakage, and the pennies were not affected by the acid at all.

      5.      Your body produces enough heat in only thirty minutes to boil a half-gallon of water

Our bodies are the epitome of a study on the laws of thermodynamics. You produce heat from all that is going on - exercise, metabolizing food, maintaining homeostasis – and as you sweat, exhale, excrete, and urinate.

      6.      ​Strongest muscle in your body

If you define strength as the ability to exert the most pressure, then the strongest muscle in the human body is the masseter muscle. Masseter muscle is the thick cheek muscle near the back of your jaw that opens and closes your mouth whenever you chew.

These are so many things you probably did not know about body. There is plenty more to know about the human body, and you can discover these facts by being inquisitive. They are really something!
