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 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.
