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 lower chambers-the right and left ventricles-pump blood out of your heart. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings (for the tricuspid and mitral valves) and exits (for the pulmonary and aortic valves).

Detailed explanation-3: -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. The left ventricle pumps the oxygen-rich blood to the body.

Detailed explanation-4: -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.

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