Question

How is gas exchange done
in mammals?

Expert Solution
Step 1

Most mammals live on land, and hence obtain oxygen by breathing air.

Gas exchange is the physical process by which gases move passively by diffusion across a surface. The process of gas exchange is important as it provides oxygen to the cells of living organisms which is utilized to obtain energy from organic molecules. 

There are three overall processes involved in gas exchange are:

  • Moving air in and out of the lungs (ventilation)
  • Oxygen-carbon dioxide exchange (diffusion)
  • Pumping blood through the lungs (perfusion)
