To pump blood throughout the body. The heart carries deoxygenated blood and it also carries oxygenated blood throughout the body.
The main functions of the heart can be summarised as follows: The right-hand side of the heart receives de-oxygenated blood from the body tissues (from the upper-and lower-body via the superior vena cava and the inferior vena cava, respectively) into the right atrium. The function of the heart is to pump blood throughout the body. The heart carries deoxygenated blood and it also carries oxygenated This de-oxygenated blood passes through the tricuspid valve into the right ventricle. This blood is then pumped under higher pressure from the right ventricle to the lungs via the pulmonary artery. The left-hand side of the heart receives oxygenated blood from the lungs (via the pulmonary veins) into the left atrium. This oxygenated blood then passes through the bicuspid valve into the left ventricle. It is then pumped to the aorta under greater pressure (as explained below). The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes. Your heart is a muscular organ that pumps blood to your body. Your heart is at the center of your circulatory system. This system consists of a network of blood vessels, such as arteries, veins, and capillaries. These blood vessels carry blood to and from all areas of Functions of the Heart, Lungs, and Blood Vessels. FUNCTIONS OF THE HEART. Arterial blood (red, oxygen-rich blood) flows from the heart to each part of the body to provide oxygen and nutrients. The venous blood (blue, oxygen-poor blood) returns from the body to the heart. The heart's main function is to pump blood, making it the  functional core of the circulatory system. Incoming,  deoxygenated blood is pumped through the right side of the h … eart  and to the lungs, where the carbon dioxide is replaced with fresh  oxygen.
