Why do we need to respire?


Question asked by: knowitall

We respire in order to exchange gases that we don't need for gases we don't.

We take in oxygen and breathe out carbon dioxide which is a waste product of respiration. All the nitrogen in the air is unreactive relatively and not affected by these processes.
