cells need oxygen to make energy. oxygen - rich blood is transported to tissues. when the oxygen is dropped off, it needs to move through structures that are small and thin. which vessels allow for oxygen movement into the tissues? arteries veins heart capillaries

cells need oxygen to make energy. oxygen - rich blood is transported to tissues. when the oxygen is dropped off, it needs to move through structures that are small and thin. which vessels allow for oxygen movement into the tissues? arteries veins heart capillaries

Answer

Brief Explanations:

Capillaries are small and thin - walled vessels where gas exchange occurs. Oxygen from oxygen - rich blood diffuses into tissues through capillaries. Arteries carry blood away from the heart and are not the main site for oxygen movement into tissues. Veins carry blood back to the heart. The heart is a pump, not a vessel for oxygen movement into tissues.

Answer:

D. capillaries
