HEALTHY HEART

The human heart is a muscular organ which pumps blood through the blood vessels of the circulatory system. The heart is divided into four chambers, upper left and right artier, and lower left and right ventricles.

The main function of the heart is the circulation of blood. This it does through two part ways; the pulmonary circuit and the systemic circuit.

In the first pathway which is the pulmonary circuit, de-oxygenated blood leaves the right ventricle of the heart via the pulmonary artery and travels to the lungs, then return as oxygenated blood to the left atrium. However in the second pathway – the systemic circuit – oxygenated blood leaves the heart through the left ventricle to the aorta and circulates to the arteries and capillaries where the body tissues are supplied with oxygen. De-oxygenated blood however returns to the heart via veins to the venae cavae, re-entering the right atrium.
