Answer 1

Answer:

Answer 2

Answer:

Three processes are essential for the transfer of oxygen from the outside air to the blood flowing through the lungs: ventilation, diffusion, and perfusion.

Explanation:

1. Ventilation is the process by which air moves in and out of the lungs.
2. Diffusion is the spontaneous movement of gases, without the use of any energy or effort by the body, between the gas in the alveoli and the blood in the capillaries in the lungs.
3. Perfusion is the process by which the cardiovascular system pumps blood throughout the lungs.
