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.
Chambers of the Heart. The heart has four chambers: two atria and two ventricles. 1  The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. 2  The right ventricle pumps the oxygen-poor blood to the lungs.  The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
