Answer 2

The one which is the correct function of the lungs is option b: To transfer some of the oxygen that you breathe to your blood.

• The pulmonary internal organs of the human body are the lung that transfers fresh oxygen to the blood and expels carbon dioxide during the process of respiration.
• The diffusion of oxygen and carbon dioxide from and to blood capillaries occurs through alveoli, which are ballon-like sacs found in the lungs.
• The heart's function is to pump oxygenated blood to all parts of the body.
• The kidney's job is to purify the blood.
• The molecules of carbon dioxide are not transformed into oxygen. They're exhaled out.
• As a result, the lungs' primary role is to transport oxygen into the bloodstream.
