❣️THANKS❣️

Answer 1

The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.

Answer 2

Oxygen is the most important for keeping us alive because body cells need it for energy and growth. ... The lungs and respiratory system allow oxygen in the air to be taken into the body.
As our body uses oxygen, it makes a waste product called carbon dioxide. We get rid of carbon dioxide when we breathe out.The major function of the lungs is gas exchangebetween the lungs and the blood.
