IMMUNOLOGY

Detailed explanation-1: -The four heart chambers and four valves work together to separate the oxygen-rich blood from the oxygen-poor blood. When healthy, the structure of your chambers and valves allows blood to flow in the right direction. The normal cycle of blood flow moves like this: body-heart-lungs-heart-body.

Detailed explanation-2: -The four-chambered heart provides an efficient solution by keeping oxygenated and non-oxygenated blood separate. The supply of oxygen to the body can also be improved by increasing how often the heart contracts.

Detailed explanation-3: -Your heart has four separate chambers that pump blood. The chambers are called the right atrium, right ventricle, left atrium, and left ventricle. The right and left sides of the heart are separated by a muscular wall that prevents blood without oxygen from mixing with blood that has oxygen.
