The heart is a muscular pump that provides the force necessary to distribute the blood to all the tissues in the body. Its function is essential since, to survive, the tissues require a constant supply of oxygen and nutrients, and metabolic waste items have to be eliminated. Deprived of these necessities, cells soon undergo irreversible changes that lead to fatality. While blood is the transportation tool, the heart is the organ that keeps the blood moving via the vessels. The normal adult heart pumps about 5 liters of blood every minute throughout life. The individual's life is jeopardized if it loses its pumping performance for even a few minutes. Both top chambers of your heart are called room, and both lower chambers are called ventricles. Blood moves from the body and lungs to the room and from the room to the ventricles. The ventricles pump blood out of the heart to the lungs and other components of the body. An inner wall of tissue separates the right and left sides of your heart. The heart is made of three layers of tissue. Some problems can influence the heart's tissue. The blood pumped by your heart provides your body with the oxygen and nutrients it needs to function. Your heart pumps the blood from the right side of your heart to your lungs so it can receive more oxygen. High blood pressure refers to the amount of pressure the pumping blood puts in on arterial wall surfaces. The shutoff on the right side of the heart is called the tricuspid shutoff, while the valve on the left side is called the mitral shutoff.
