MICROANATOMY

Detailed explanation-1: -The bottom 2 chambers are called the right and left ventricles. Each of these chambers has a valve that keeps blood flowing in 1 direction. The valves in this picture appear in gray. When the heart is working normally, blood comes in from the body through the right atrium and into the right ventricle.

Detailed explanation-2: -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-3: -The heart has four chambers: two atria and two ventricles. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. 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.

Detailed explanation-4: -A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart.

Detailed explanation-5: -The upper chambers of the heart are called atria which always receive blood. The lower two chambers are called ventricles which pump the blood out of the heart to various parts of the body.
