The heart acts as the central pump for the circulatory system, responsible for circulating blood throughout the body as described in [1], [2], and [3]. Blood enters and exits the heart through specific chambers and valves to facilitate systemic and pulmonary circulation, as detailed in [4], [5], [6], and [7].

claimBlood enters the heart through the upper chambers of the left and right atria and exits via the left and right ventricles.
claimVenules leave capillaries and increase in size to become veins, which return blood to the heart.
claimThe main functional difference between arteries and veins is the direction in which they conduct blood: arteries convey blood from the heart to the periphery, while veins convey blood from the periphery 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 enters the heart through the left and right atria and exits via the left and right ventricles.
claimThe circulatory system consists of three separate circuits: the pulmonary circulation (between heart and lungs), the coronary circulation (supplying blood to the heart muscle), and the systemic circulation (carrying blood to the rest of the body).
claimHeart valves function to prevent the backflow of blood within the heart.
claimIn the human heart, blood enters through the left and right atria and exits via the left and right ventricles, with heart valves preventing the backflow of blood.
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.
claimArteries convey blood from the heart to the periphery, while veins convey blood from the periphery 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.
procedurePulmonary circulation involves the right side of the heart pumping oxygen-depleted blood to the lungs via the pulmonary artery, where the blood releases carbon dioxide and picks up oxygen before returning to the left side of the heart through the pulmonary veins.
claimThe left ventricle of the heart has a thicker muscular wall than the other chambers, which facilitates its role in pumping blood throughout the body.
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.

claimAn organ is a group of tissues that constitutes a distinct structural and functional unit, such as the heart, which is composed of all four tissue types and functions to pump blood.
claimThe circulatory system is composed of the heart, blood, and blood vessels; it circulates transport fluid to provide cells with oxygen and nutrients while removing waste products like carbon dioxide and toxic nitrogen compounds.

claimThe cardiovascular system, also known as the circulatory system, is responsible for transporting blood and essential substances throughout the body and consists of the heart, blood vessels, and blood.
claimCardiac muscles are specific to the heart and contract to pump blood throughout the body, ensuring organs receive oxygen and nutrients.

referenceThe circulatory system circulates blood to transport nutrients, waste, hormones, oxygen, and carbon dioxide, and aids in maintaining pH and temperature, utilizing blood, the heart, arteries, veins, and capillaries.
