Chapter 3 - Breathing and Gas Exchange

We breathe everyday, hour, minute and second but what is breathing? You know it's that inhaling and exhaling thing we do everythin' mate! But guys, I'll tell you that it's more than that!

Breathing is the process of getting oxygen into the lungs and carbon dioxide out of the lungs. It allows for gas exchange to take place so that oxygen can be absorbed from the lungs into the blood and carbon dioxide is removed from the blood and breathed out from the lungs.

Many people say that breathing and respiration are the same. Nope, they are not the same.

Respiration is the release of energy from the break down of glucose in living cells. Respiration takes place in every living cell and all cells need to respire to produce the energy they need.

BIG difference!!
