The heart is divided into four chambers, the left and right atria (the top chambers) and the left and right ventricles (the bottom chambers). A thick wall called the septum separates the left side of the heart from the right. Four valves that act as one-way doors within the heart carefully regulate blood flow through the heart’s chambers keeping blood on a “one-way street” through the heart and out to the body.

What does the heart consist of?
Is it okay to interview my potential surgeon?
Debra Fulghum Bruce PhD, Healthcare, answeredMedicine is changing dramatically. In years past we relied on our doctors to provide medical care and keep us well. However, the traditional, autocratic role of doctors is now challenged by millions of people as they seek to make informed choices regarding their bodies and necessary health care. While you may feel uncomfortable interviewing a surgeon and asking pertinent, even personal questions regarding his or her knowledge and experience, you must do it to find that professional with whom you can trust your life.

How does the heart pump blood?
Mehmet Oz, MD, Cardiology, answeredThe heart pumps blood through a coordinated series of contractions that send blood through the four chambers of the heart and on to the rest of the body. It’s an efficient system that begins with oxygen-depleted blood entering the right atrium. When it is full of blood, the atrium contracts, sending the blood into the right ventricle. During all of this, the four valves of the heart open and shut quickly to keep blood flowing in one direction only. From there, the blood is pumped through the pulmonary veins into the lungs.
At the same time, oxygen-rich blood is returning from the lungs to the heart and flows into the left atrium. The left atrium contracts, sending that blood into the left ventricle. From there, blood is pumped to the aorta, the main artery that carries blood, and it can now be distributed to the rest of the body’s organs and tissues.Helpful? 3 people found this helpful.
