The cardiac ventricles are the two lower chambers of the heart's four chambers. They are larger and more narrowed than the atria. They function by collecting the blood that flows into them from the atria and then contract in order to expel blood into the peripheral tissues, using major vessels to carry it to the extremities and lungs.

Hearts four chambers?

The heart has four chambers. The two ventricles (right and left) are muscular chambers that propel the blood out of the heart (the right ventricle to the lungs, and the left ventricle to all other organs). The two atria (right and left) hold the blood returning to the heart, and at just the right moment empty into the right and left ventricles...
