The atria
The Left Ventricle has the thickest walls! The left ventricular myocardium is much thicker then the right ventricular myocardium because the left ventricle pumps blood into the aorta which takes blood to the rest of the body. (larger pressure gradient)
The ventricles of the heart function to pump blood to the entire body. Right ventricle: receives blood from the right atrium and pumps it to the pulmonary artery (to lungs). Left ventricle: receives blood from left atrium and pumps to aorta (to rest of body).
The left ventricle pumps blood into the aorta and that takes it out to the body
Blood enters the heart through the inferior or superior vena cava, then goes through the right atrium, into the right ventricle, and into the pulmonary artery, which takes the blood to the lungs for oxygen.
After the blood is oxygenated in the pulmonary vessels it is then taken to the left atrium and then flows throught the valve in the heart and sent to the left ventricle where the heart then beats or pumps the oxygenated blood to the body
After taking oxygen from the lungs the blood travels to the left atrium of the heart. From here the blood is pumped to the left ventricle. The left ventricle then pumps the oxygenated blood into the aorta through which it flows to the rest of the body.
The left ventricle. Blood from the body comes into the right atrium goes into the right ventricle and is then pumped to the lung comes back to the left atrium and then left ventricle to the aorta to the body.
The left side of the heart is bigger because it has to pump harder to get the oxygenated blood all the way around your body. The right side merely receives de-oxygenated (venous) blood.
The heart is split into four parts so as to be able to function properly. They four chambers are left and right atrium and left and right ventricles. Oxygen-poor blood is received by right atrium which pumps it to the right ventricle that takes it to the lungs. When blood is oxygenated, it is received by the left atrium which pumps it to the left ventricle to be circulated to the body.
The receiving chambers of the heart are the two chambers on the top, the atria. The right atrium takes venous blood from the body, and the left atrium collects blood coming from the lungs where it has been oxygenated. The serious pumping happens in the ventricles, the two chambers below the atria. The right ventricle pumps the blood to the lungs, and the left ventricle pumps the blood out into the body, both pumping at the same time.
The left ventricle. Blood flows from your body back to the right atrium through the right ventricle then to the lungs to get oxygen. It then goes to the left atrium to the left ventricle, which is the largest, most muscular part of the heart because it pumps the oxygenated blood back to the body.
Right atrium then right ventricle.
