Detailed explanation-1: -The lower chambers-the right and left ventricles-pump blood out of your heart. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings (for the tricuspid and mitral valves) and exits (for the pulmonary and aortic valves).

Detailed explanation-2: -ventricles (VEN-trih-kuhls): The two chambers at the bottom of the heart are called the ventricles. The heart has a left ventricle and a right ventricle. Their job is to pump the blood to the body and lungs.

Detailed explanation-3: -The heart has four chambers. The upper two chambers are the atria, and the lower two are the ventricles (Figure A). The chambers are separated by a wall of tissue called the septum. Blood is pumped through the chambers, aided by four heart valves.

Detailed explanation-4: -Your lower chambers are called your right ventricle and left ventricle. Your chambers work together to manage your heartbeat. They also send blood into your lungs to gain oxygen before recirculating throughout your body.

Detailed explanation-5: -ventricle, muscular chamber that pumps blood out of the heart and into the circulatory system.
