The heart and capillaries are both integral components of the circulatory system, as described in [1], [2], and [3]. The heart acts as the pump that drives blood through a network of vessels, including arteries that lead to capillaries for nutrient exchange, and veins that return blood from capillaries back to the heart, as detailed in [4], [5], and [6].

claimVenules leave capillaries and increase in size to become veins, which return blood to the heart.
claimIn the human circulatory system, venules leave capillaries and gradually increase in lumen size to become veins on the way back to the heart.
claimBlood leaves the heart via arteries, which progressively reduce in size to become smaller arterial vessels called arterioles, which then end in a web of even smaller vessels called capillaries.
claimBlood leaves the heart via arteries, which reduce in size to become arterioles, which then end in a web of capillaries where the exchange of gases and nutrients occurs.
claimSmall veins, called venules, originate from capillaries and gradually increase their lumen size as they travel toward the heart to end as veins.
claimVenules are small veins that leave capillaries and increase in lumen size to become veins as they return to the heart.

procedureSystemic circulation involves the left side of the heart pumping oxygen-rich blood through the aorta, which branches into smaller arteries and capillaries to exchange oxygen and nutrients with cells, before deoxygenated blood returns to the heart via veins.
quoteYour circulatory system, or cardiovascular system, supplies oxygen and nutrients to your whole body and removes waste through your blood. Your heart pumps blood that flows through your arteries, veins and capillaries. These blood vessels and your heart form your circulatory system. They work together to ensure your cells have what they need.
