Question

question 9 of 10 where does carbon dioxide move from the circulatory system to the respiratory system? a. in the vena cava b. in the alveoli c. in the liver d. in the pulmonary artery

Explanation:

Gas exchange between the circulatory and respiratory systems occurs in the alveoli. Carbon - dioxide diffuses from the blood in the capillaries surrounding the alveoli into the alveoli to be exhaled. The vena cava is a large vein that returns de - oxygenated blood to the heart. The liver is mainly involved in metabolism and detoxification. The pulmonary artery carries de - oxygenated blood from the heart to the lungs, but gas exchange does not occur within the artery itself.

Answer:

B. In the alveoli
