This would include the left and right atrium and the left and right ventricle. Both of the left and right ventricles have a particular difference when it comes to their functions. The ventricles are the two lower chambers of the heart. These ventricles are divided into two parts: the left ventricle and the right ventricle. The left ventricle and the right ventricle pump out blood from the heart going to the arteries to supply blood to the different parts of the body.
The right ventricle pumps the deoxygenated blood (received from the right atrium) to the... pulmonary artery to the lungs = pulmonary circulation. Oxygenated blood from the lungs returns to the... left atrium via the pulmonary veins and is pumped into the left ventricle.
