The four main functions of the heart are: Pumping oxygenated blood to the other body parts. ... Receiving deoxygenated blood and carrying metabolic waste products from the body and pumping it to the lungs for oxygenation. Maintaining blood pressure.
Answer:
The right ventricle gets blood from the right atrium and pumps it to the lungs to load it with oxygen.
The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.
The left ventricle is the strongest chamber of the heart. It pumps oxygen-rich blood to the rest of the body.
The flow of blood into the heart, within the heart chambers and from the heart is guarded by the four valves present in the heart. The heart gets its nutrients and oxygen via the coronary arteries that run along the surface of the heart. It is also richly supplied by a web of nerve tissue that facilitates the rhythmic heartbeat. The heart is enclosed within a fluid-filled sac called the pericardium. The pericardium is a protective covering that produces fluid, which lubricates the heart and prevents friction between the heart and the surrounding organs.
