Explanation
## Step 1:The question pertains to the human circulatory system, specifically the components that facilitate the transport of blood from the body back to the heart. ## Step 2:Arterioles are small branches of arteries that lead to capillaries, which are the smallest blood vessels in the body. They are not responsible for transporting blood back to the heart.## Step 3:Capillaries are the smallest blood vessels and they connect arterioles to venules. They facilitate the exchange of oxygen, carbon dioxide, and other substances between blood and body tissues. However, they do not transport blood back to the heart.## Step 4:Arteries are blood vessels that carry oxygenated blood away from the heart to the body's tissues. They do not transport blood back to the heart.## Step 5:Veins are blood vessels that carry deoxygenated blood from the body back to the heart. This is the primary function of veins in the circulatory system, with the exception of the pulmonary and umbilical veins, which carry oxygenated blood.
