WHY? Answers To Impossible Questions - PART 1
WHY should you read this article?
Because.....It contains hundreds of homework material and riveting responses.
For part 1, I am going to give you some great answers to frequent questions about the human body........
1. Can we survive without our organs?
It's a no-brainer that you need your brain and heart, and you wouldn't last long if your liver failed. But the lungs and kidneys come in pairs, so you could survive if one of them failed. People who lost their spleen in accidents have gone on to live healthy lives. The tonsils and appendix, meanwhile, are practically useless and are routinely removed when they become inflamed.
2. Why do we yawn?
Everybody yawns-even unborn babies in the womb-but researchers aren't quite sure why we do it. Although humans yawn more often when we are tired or bored, scientists have ruled out sleepiness or lack of oxygen as causes. Instead, they suspect yawning might help us keep a cool head. As with a supercomputer, the brain needs to keep cool to function properly. Each yawn pumps air into the sinus cavities in the head, cooling the brain in the process.
3. Why do we have 10 fingers?
Scientists have several ideas why humans can high five each other instead of, say, high four or high six. One theory suggests four fingers and a thumb on each hand are perfect numbers and lengths to grip objects firmly. The process of evolution determined the most beneficial number of fingers and toes for survival. Pandas, after all, have thumb-like digits to help grasp bamboo. Occasionally, babies are born with extra thumbs or toes, a condition called polydactyl. After all, evolution determined that five fingers per hand are just right for humans.
4. Why do we get dizzy when we spin?
Your ears do more than just hear your brother's burp or act as earring support. They contain special organs that help you detect motion, tell up from down, and keep you from tumbling when you trip. Whenever you move or tilt your head, fluid moving through your canals in your inner ears interacts with tiny hairs along your canal walls, telling your brain that your in motion. When you spin the fluid moves along with you. Stop and the fluid keeps spinning, sloshing against your hairs and making your brain think you are still spinning - making you dizzy.
5. Why do we sneeze?
Sometimes dust, flakes of dead skin, pollution, microbes, your own booger build up from cold find their way into your nose's air passages. When mucous membranes detect these intruders, they send an urgent message to your brain: UNLEASH A SNEEZE.
