Why must the heart contract very strongly to pump blood from the left ventricle into the aorta? What is the order in which the heart pumps blood? Right Atrium, right ventricle, lungs, left atrium, left ventricle, then it goes all over the body, comes back to the heart and repeats the process.     For the heart t…o function properly, the four chambers must beat in an organized manner. The four heart chambers fill with and pump blood.

When the heart muscle contracts or beats (called systole), it pumps blood out of the heart. The heart contracts in two stages. In the first stage, the right and left atria contract at the same time, pumping blood to the right and left ventricles. Then the ventricles contract together to propel blood out of the heart. Then the heart muscle relaxes (called diastole) before the next heartbeat. This allows blood to fill up the heart again. The right and left sides of the heart have separate functions.

contracts, systemic. (Mammalian Heart) 4. The oxygen-rich blood flows into the left ventricle, as the ventricle opens and the atrium ---. The left ventricle pumps the oxygen-rich blood out to body tissues and through the --- circuit.

The ventricles, on the other hand, have a very thick myocardium to pump blood to the lungs or throughout the entire body. The right side of the heart has less myocardium in its walls than the left side because the left side has to pump blood through the entire body while the right side only has to pump to the lungs. Chambers of the Heart. The heart contains 4 chambers: the right atrium, left atrium, right ventricle, and left ventricle. The atria are smaller than the ventricles and have thinner, less muscular walls than the ventricles. The atria act as receiving chambers for blood, so they are connected to the veins that carry blood to the heart.

These arteries carry blood to the lungs to be oxygenated.   Oxygenated blood is returned to the heart by pulmonary veins. This oxygenated blood enters the left atrium. Blood from the left atrium flows across an open mitral valve to enter the left ventricle. As the left ventricle starts to contract the mitral valve closes and the aortic valve opens as blood is pumped across it into the aorta.The aorta and arteries that branch from it carry blood to the entire body. The left ventricle is the largest and most forcefully contracting chamber of the heart.

Blood returns to the heart from the lungs via the pulmonary veins. The blood goes into the left atrium. When the left atrium contracts, blood travels through a valve into the left ventricle. The left ventricle is a very important chamber because it pumps blood through a valve and into the aorta. The aorta - the main artery of the body - receives all the blood that the heart pumps out and sends it to the rest of the body. The left ventricle has a thicker muscle than any other heart chamber.

When the right atrium contracts, blood flows through a valve into the heart's right ventricle. When the right ventricle contracts, blood is pumped through a valve into the pulmonary artery and into the lungs where it picks up oxygen. It works this way for an important reason.

The right side of the heart maintains pulmonary circulation to the nearby lungs while the left side of the heart pumps blood all the way to the extremities of the body in the systemic circulatory loop. The heart functions by pumping blood both to the lungs and to the systems of the body.
