Amazing Facts About Human Body

A Human body is an ever changing biological phenomenon. We as human are not aware of many things. There’s a lot to know about the human structure.

Here are 10 such intresting facts about the human structure which we are not aware of.

1. The brain is a very wrinkly organ. If you spread it out, your brain would be about the size of a pillowcase. By the time you are 6 years old, your brain is already 90% of the size it will be when your adult.

2. The only reason the acid in our stomach doesn’t eat right through our body is because the stomach cells are renewed faster than they are destroyed. Our stomach acid are strong enough to dissolve razor blades.

3. Sweat doesn’t smell bad. A stinky body odour is caused when the skin bacteria feed on sweat. Their waste products are what smell bad.

4. The cracking sound made by knuckles, necks, backs and other joints when they are cracked is the sound of bubbles popping in the joints fluid. It is not terribly harmful but cracking a joint too often can hurt the ligaments, that surround the joint.

5. 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 also means your heart must work harder to pump blood through the new network, which may reduce oxygenation and nutrient replenishment in other tissues. Lose a pound? Your body will break down and reabsorb the unneeded blood vessels from the previous tissue.

6. Muscle tissue is three times more efficient at burning calories than fat. This is why possessing more muscle should be a training goal for most people. More muscle = more calories burned = less fat = being more fit looking. Simple goals and simple math.

7. You are taller in the morning than in the evening. When you crawl out of the sack in the morning you are at your tallest. On average, you are approximately one half inch taller when you wake 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 results in you losing a small amount of extra height.

8. By the age of eighteen your brain stops growing. From that age forward it begins to lose more than 1,000 brain cells every day. Only two percent of your body weight is occupied by your gray matter, but is uses up to 20% of your overall energy output (it needs carbohydrates). Your brain works continuously and never rests, even when you’re asleep. Aside from producing REM dreams, your brain works overtime to replenish its ability to function normally during your daytime waking hours.
