GROSS ANATOMY

Detailed explanation-1: -The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart. The heart then sends the blood to the lungs to pick up more oxygen.

Detailed explanation-2: -Your heart pumps blood around the body all the time-about five litres (eight pints) of it-and this is called circulation. Your heart, blood and blood vessels together make up your cardiovascular system (or heart and circulatory system).

Detailed explanation-3: -The heart’s primary function is to pump blood throughout the body. It supplies oxygen and nutrients to the tissues and removes carbon dioxide and waste from the blood. It also helps to maintain adequate blood pressure throughout the body.

Detailed explanation-4: -The heart is an organ which beats continuously to act as a pump for the transport of blood, which carries other substances with it. The heart pumps the deoxygenated blood to the lungs for oxygenation and receives oxygenated blood from lungs. It pumps the oxygenated blood to different parts of the body.

Detailed explanation-5: -The circulatory system delivers oxygen and nutrients to cells and takes away wastes. The heart pumps oxygenated and deoxygenated blood on different sides. The types of blood vessels include arteries, capillaries and veins.
