What are the four chambers of the heart made of? The heart is comprised of the left and right atria and the left and right ventricles. The atria pump blood to the lungs, where it is oxygenated. The oxygenated blood then retu…rns to the heart, where the ventricles pump it to the rest of the body.

The heart’s four chambers are: 1  Right atrium: This chamber receives oxygen-depleted blood that has already circulated around the body and pumps it into the right ventricle.  Right ventricle: The right ventricle pumps blood from the right atrium to the pulmonary artery.

Chambers and the valves of the heart. A normal heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of your heart. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings.

The heart has four valves that separate each chamber so that, under normal conditions, blood cannot flow backwards. These valves can sometimes be replaced if they become damaged. The heart’s valves are: Tricuspid (right AV) valve: This valve opens to allow blood to flow from the right atrium to the right ventricle.

1 Right ventricle: The right ventricle pumps blood from the right atrium to the pulmonary artery. The pulmonary artery sends the deoxygenated blood to the lungs, where it picks up oxygen.  Left atrium: This chamber receives oxygenated blood from the lungs and pumps it to the left ventricle.

The four chambers of the heart are as follows:    Left atrium  Right atrium  Left ventricle  Right ventricle    The blood travels from the body into the right a…trium and is pumped  through the right ventricle to the lungs. Here it exchanges gases  and returns to the heart.

The heart’s four chambers function as a double-sided pump. The right side of the heart takes in oxygen-depleted blood from the organs. This blood is delivered to the heart through the veins. The chambers on the left side pump oxygen-rich blood out to the body through arteries.

The right atrium and ventricle transport blood to the lungs. This blood is oxygen-poor and needs to be replenished. The blood returns to the heart into the left atrium and ven…tricle. This blood is oxygen-rich, and the heart transports it to the rest of the body.

1 Left atrium: This chamber receives oxygenated blood from the lungs and pumps it to the left ventricle.  Left ventricle: The thickest of all the chambers, the left ventricle is the hardest working part of the heart as it pumps blood throughout the whole body.

The heart consist of 4 chambers-2 atria and 2 ventricle. The atria is about 1/3 the size of the ventricle. The left ventricle is the largest chamber of the heart. The left ventricle has about three time the mucsle than the right ventricle. The chambers of the heart provide a multiple step pathway for blood to be first sent to the lungs for respiration and then dispensed to the body's cells to keep us alive.
