MICROANATOMY

Detailed explanation-1: -The heart is made up of four chambers. The upper chambers are the called atria and act as the receiving chambers. The lower chambers are called ventricles; these are the pumping chambers. There are four valves within the heart, which help control the direction of blood flow.

Detailed explanation-2: -The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. 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.

Detailed explanation-3: -The heart functions as a double ventricle. Blood moves from the body into the right atrium, and then into the right ventricle where it gets pumped into the lungs. Blood gets oxygenated in the lungs, moves into the left atrium, and into the left ventricle where it gets pumped into the body again.

Detailed explanation-4: -The two upper chambers of your heart are called atrium, and the two lower chambers are called ventricles. Blood flows from the body and lungs to the atria and from the atria to the ventricles. The ventricles pump blood out of the heart to the lungs and other parts of the body.

Detailed explanation-5: -Right atrium. Right ventricle. Left atrium. Left ventricle.
