which of the following is not transferred by alveoli? a. oxygen b. blood c. carbon dioxide d. gases please select the best answer from the choices provided.
Answer
Brief Explanations:
Alveoli are tiny air - sacs in the lungs where gas exchange occurs. Oxygen from inhaled air diffuses into the blood, and carbon dioxide diffuses out of the blood into the alveoli to be exhaled. Gases (oxygen and carbon dioxide) are transferred, but blood itself is not transferred by alveoli. It just passes by for gas exchange.
Answer:
B. blood
