Facts about Body Functions

Some Interesting Facts about Body Functions

We may not always like to talk about them, but everyone has to deal with bodily functions on a daily basis. These are a few facts about the involuntary and sometimes unpleasant actions of our bodies.

1. Sneezes regularly exceed 100 mph. There's a good reason why you can't keep your eyes open when you sneezeâ that sneeze is rocketing out of your body at close to 100 mph. This is, of course, a good reason to cover your mouth when you sneeze.
2. 
   
3. Coughs clock in at about 60 mph. Viruses and colds get spread around the office and the classroom quickly during cold and flu season. With 60 mph coughs spraying germs far and wide, it's no wonder.
4. 
   
5. Women blink twice as many times as men do. That's a lot of blinking every day. The average person, man or woman, blinks about 13 times a minute.
6. 
   
7. A full bladder is roughly the size of a soft ball. No wonder you have to run to bathroom when you feel the call of the wild. The average bladder holds about 400-800 cc of fluid but most people will feel the urge to go long before that at 250 to 300 cc.
8. 
   
9. Approximately 75% of human waste is made of water. While we might typically think that urine is the liquid part of human waste products, the truth is that what we consider solid waste is actually mostly water as well. You should be thankful that most waste is fairly water-filled, as drier harder stools are what cause constipation and are much harder and sometimes painful to pass.
10. 
    
11. Feet have 500,000 sweat glands and can produce more than a pint of sweat a day. With that kind of sweat-producing power it's no wonder that your gym shoes have a stench that can peel paint. Additionally, men usually have much more active sweat glands than women.
12. 
    
13. During your lifetime, you will produce enough saliva to fill two swimming pools. Saliva plays an important part in beginning the digestive process and keeping the mouth lubricated, and your mouth produces quite a bit of it on a daily basis.
14. 
    
15. The average person expels flatulence 14 times each day. Even if you'd like to think you're too dignified to pass gas, the reality is that almost everyone will at least a few times a day. Digestion causes the body to release gases which can be painful if trapped in the abdomen and not released.
16. 
    
17. Earwax production is necessary for good ear health. While many people find earwax to be disgusting, it's actually a very important part of your ear's defense system. It protects the delicate inner ear from bacteria, fungus, dirt and even insects. It also cleans and lubricates the ear canal.
