What is the correct order of processes involving the movement of oxygen from the environment to mitochondria in vertebrates?
Nuetrik [128]

Answer:

a.) ventilation, circulation, cellular respiration

Explanation:

a.) ventilation, circulation, cellular respiration

b.) diffusion in tissues, cellular respiration, diffusion at respiratory surface

c.) ventilation, diffusion in tissues, circulation

d.) circulation, cellular respiration, diffusion in tissues

e.) circulation, ventilation, cellular respiration

Ventilation occurs in the lungs and is the process by which carbon dioxide in the capillaries is lost to the environment while oxygen is taken in. Circulation is the process by which this dissolved oxygen is taken by the blood to tissues around the body. When this oxygen is taken to tissue, the concentration gradient allows the oxygen to be taken up by tissue. This oxygen is used as an electron acceptor (when it reduced to water) in the mitochondria during electron transport chain of cellular respiration.
