€ 4. where does the exchange of gases take place?

■ C. Alveoli

€ 5.Where is the diaphragm located?

■ D. below the lungs

MORE INFORMATION:

The alveoli also increase the surface area of the lungs for greater exchange of gases to collect more oxygen. In addition, the alveoli also protect the lungs from pathogens.

Below the lungs is the diaphragm. It is a dome-shaped muscle that controls breathing. When we inhale, the diaphragm contracts and pulls air inward and it relaxes when we enhale, thus, expelling the air rich with carbin dioxide out.
