PATHOLOGY

Detailed explanation-1: -The right atrium and ventricle are often referred to together as the right heart, and the left atrium and ventricle as the left heart. As the atria do not have valves at their inlets a venous pulsation is normal, and can be detected in the jugular vein as the jugular venous pressure.

Detailed explanation-2: -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-3: -If you look at a diagram of a heart, these chambers divide into upper and lower chambers and left and right chambers. Atria are your two upper heart chambers. You have a left atrium and a right atrium. Ventricles are your two lower heart chambers.

Detailed explanation-4: -Your heart is slightly on the left side of your body. It sits between your right and left lungs. The left lung is slightly smaller to make room for the heart in your left chest.
