Final answer:
Oxygen and carbon dioxide gas exchange occurs in the lungs and between capillaries and tissues due to partial pressure differences. The student's statement is True.
Step-by-step explanation:
The student's statement is True.
In the lungs, oxygen diffuses out of the alveoli and into the capillaries surrounding the alveoli. On the other hand, carbon dioxide diffuses out of the capillaries and into the alveoli. This gas exchange process occurs because of the partial pressure differences between the alveoli and the blood in the pulmonary capillaries.
Additionally, in the systemic capillaries, oxygen diffuses out of the capillaries into the tissue cells, while carbon dioxide diffuses out of the tissue cells and into the capillaries. Again, this exchange is driven by partial pressure differences between the blood and the tissues.
