PATHOLOGY

Detailed explanation-1: -The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.

Detailed explanation-2: -The right atrium receives blood from the body. This blood is low in oxygen. This is the blood from the veins. The right ventricle pumps the blood from the right atrium into the lungs to pick up oxygen and remove carbon dioxide.

Detailed explanation-3: -Oxygen-poor blood from the body enters your heart through two large veins called the superior and inferior vena cava. The blood enters the heart’s right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs.

Detailed explanation-4: -The right side of the heart collects oxygen-depleted blood and pumps it to the lungs, through the pulmonary arteries, so that the lungs can refresh the blood with a fresh supply of oxygen.
