ANATOMY

Detailed explanation-1: -These bring blood from the body to the right atrium. Next is the pulmonary artery that carries blood from the right ventricle to the lungs. The aorta is the body’s largest artery. It carries oxygen-rich blood from the left ventricle to the rest of the body.

Detailed explanation-2: -The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.

Detailed explanation-3: -The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where the blood 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-4: -Electrical pulses make your heart muscles squeeze and release. That action pushes blood through the two chambers on the right side of your heart and out to the lungs where it gathers oxygen. A vein then carries that oxygen-rich blood into the left side of the heart.

Detailed explanation-5: -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.
