Why we need to breath?
Answers
Answer:
Everyday functions of the body like digesting your food, moving your muscles or even just thinking, need oxygen. When these processes happen, carbon dioxide is produced as a waste product. The job of your lungs in this system is to provide these processes with oxygen and to get rid of the waste gas, carbon dioxide.
Explanation:
What do you need to do to survive each and every day here on Earth? If you're like most kids, eating and drinking are the two things that probably come to mind first.
However, there's one other important thing you need to do constantly to survive. What are we talking about? Breathing, of course!
We do it so often — and without thinking — that it's easy to forget about. We can go days without water and possibly weeks without food. We can't go minutes without breathing, though!
But why is that? What purpose does breathing serve? The importance of breathing is linked directly to the importance of one particular element your body needs constantly: oxygen.
