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?\no arteries\no veins\no heart\no capillaries

Answer

Brief Explanations:

Capillaries are small and thin - walled vessels where gas exchange occurs. Oxygen diffuses from oxygen - rich blood in capillaries into tissues. Arteries carry blood away from the heart and are thicker - walled. Veins carry blood back to the heart. The heart is a muscular organ that pumps blood, not a vessel for oxygen movement into tissues.

Answer:

D. capillaries
