Question

How is blood oxygenated in the lungs?

Answer 1

Oxygenation of blood:

1. The oxygenation of the blood is the process of supplying oxygen to the deoxygenated blood in the lungs.
2. Blood from the rest of the body enters the heart into the right atrium and passes through the right ventricle.
3. The right ventricle pumps the blood to the lungs where the oxygenation of blood occurs at the epithelial surface of alveoli sacs in the lungs via diffusion.
4. The oxygenated blood is returned back to the heart by the pulmonary veins for circulation.
5. Carbon dioxide is exchanged via this process in place of oxygen.
