After the blood has supplied cells throughout the body with oxygen and nutrients, it returns deoxygenated blood to the right atrium of the heart. The deoxygenated blood flows down from the right atrium to the right ventricle. The heart then pumps it out of the right ventricle and into the pulmonary arteries to begin pulmonary circulation.

Rotate the 3D model to see how the heart's valves control blood flow between heart chambers and blood flow out of the heart. The heart is a hollow, muscular organ that pumps oxygenated blood throughout the body and deoxygenated blood to the lungs. This key circulatory system structure is comprised of four chambers.

Blood cells are examined in a separate chapter. The heart is a pump that contracts rhythmically sending blood through the cardiovascular system. The contractile wall of the heart, the myocardium, is composed of cardiac muscle cells. The heart consists of four chambers: two atria and two ventricles.

Blood is carried from your heart to the rest of your body through a complex network of arteries, arterioles, and capillaries. Blood is returned to your heart through venules and veins.

Each day, your heart beats around 100,000 times. This continuously pumps about 5 litres (8 pints) of blood around your body through a network of blood vessels (called arteries and veins) in your circulatory system. This blood delivers oxygen and nutrients to all parts of your body to help your organs and muscles work properly.

2023年11月8日 · After delivering oxygen and nutrients to all your organs and tissues, your blood enters your heart and flows to your lungs to gain oxygen and get rid of waste. It then flows back to your heart, which pumps the refreshed blood out through your aorta to nourish your body again.
