which statements explain the gas exchange that happens at the alveoli? check all that apply. carbon dioxide moves from the air in the alveoli to the blood. carbon dioxide moves from the blood to the air in the alveoli. the capillaries that surround the alveoli exchange both carbon dioxide and oxygen. the capillaries that surround the alveoli exchange only oxygen. oxygen is absorbed by the blood in the capillaries that surround the alveoli. oxygen is the air we breathe out when we exhale.

Answer

Brief Explanations:

Gas exchange in alveoli involves carbon - dioxide moving from blood to alveolar air and oxygen moving from alveolar air to blood. Capillaries around alveoli exchange both gases. Oxygen is inhaled and carbon - dioxide is exhaled.

Answer:

B. Carbon dioxide moves from the blood to the air in the alveoli. C. The capillaries that surround the alveoli exchange both carbon dioxide and oxygen. E. Oxygen is absorbed by the blood in the capillaries that surround the alveoli.
