     • The short answer is that deoxygenated blood from the body enters the right atrium of the heart and the right ventricle pumps it to the lungs. The oxygenated blood returns to the heart, entering the left atrium, while the left ventricle pumps it to the body.

   As the atrial muscles contract from the superior portion of the atria toward the atrioventricular septum, pressure rises within the atria and blood is pumped into the ventricles through the open atrioventricular (tricuspid, and mitral or bicuspid) valves.

   Blood pumped by the heart flows through a series of vessels known as arteries, arterioles, capillaries, venules, and veins before returning to the heart. Arteries transport blood away from the heart and branch into smaller vessels, forming arterioles.

   The blood that is returned to the right atrium is deoxygenated, then passed into the right ventricle to be pumped through the pulmonary artery to the lungs for reoxygenation and removal of carbon dioxide. The left atrium receives newly-oxygenated blood from the lungs through the pulmonary veins.

   How does the atria pump blood into the ventricles?

   • As blood flows into the atria, the pressure will rise, so the blood will initially move passively from the atria into the ventricles. When the action potential triggers the muscles in the atria to contract (atrial systole), the pressure within the atria rises further, pumping blood into the ventricles.

   Which heart valve ejects blood into the aorta?

   • The left ventricle is the major pumping chamber for the systemic circuit; it ejects blood into the aorta through the aortic semilunar valve. A transverse section through the heart slightly above the level of the atrioventricular septum reveals all four heart valves along the same plane (Figure 19.11).

   What is a cardiac atrium?

   • Much like the wide, open architectural atrium that functions as receiving sites for incoming guests, the cardiac atrium is a pair of chambers situated at the upper part of the heart that receives systemic and pulmonary blood. The right atrium receives deoxygenated blood from the systemic circulation via the superior and inferior vena cava.

   How does the left atrium circulate blood?

   • The left atrium receives newly oxygenated blood from the lungs through the pulmonary veins, which is passed into the strong left ventricle to be pumped through the aorta to the different organs of the body. The Heart: Circulation of blood through the chambers of the heart.

   What is the function of the atria?

   • Both atria carry out three distinct functions in an ordered sequence. While the ventricles are contracting and the atrioventricular valves are closed, blood still continuously flows from the venae cavae on the right, and the pulmonary veins on the left, to fill the atria. During this phase, the atria act as reservoirs that store blood temporarily.

   Apr 19, 2023 · The left ventricle receives oxygenated blood from the left atrium, and pumps it through the aortic orifice (guarded by the aortic valve) into the aorta. In the anatomical position, the left ventricle forms the apex of the heart, as well as the left and diaphragmatic borders.
