Question

Blood moves through blood vessels in which of the following sequences,starting from the heart?
A) arteries arterioles venules capillaries veins
B) arterioles arteries capillaries vein s venules
C) arteries arterioles capillaries venules veins
D) arteries capillaries veins arterioles venules

Accepted Answer

The correct sequence is arteries arterioles capillaries venules veins. Blood is pumped from the heart into the arteries, which branch into smaller arterioles. The arterioles lead to capillaries, where exchange of nutrients and gases occurs between blood and surrounding tissues. The venules then collect the blood from capillaries and lead to larger veins, which ultimately return the blood to the heart. This sequence is important in maintaining blood flow and pressure throughout the body.
