Aorta is the largest artery present in the body. It originates from the left ventricle and extends down to the abdomen. The aorta distributes oxygenated blood to all parts of the body.

The human heart allows the complete separation of the deoxygenated and oxygenated blood. It has four chambers, the upper two atria and the lower two ventricles. The right side chambers (right atrium and right ventricle) are concerned with the deoxygenated blood. The right atrium receives the deoxygenated blood from the body and the right ventricle pumps it to the lungs. This is the pulmonary circulation. It completes when the left side chamber of the left atrium receives it. So, the left side chambers are concerned with oxygenated blood. The left ventricle then transports it to the rest of the body in the systemic circulation. So, the pulmonary and the systemic circulation maintained by the human heart constitute the double circulation of the blood.

Vaso means vessels and constriction means narrowing, therefore, narrowing of blood vessels results in vasoconstriction. Normally, it is done due to the shrinking of smooth muscles of vessels to react according to the environment by raising blood pressure for stabilization, prevent loss of heat, control blood flow in body, transfer nutrients and prevent from blood and fluid loss but in some cases it can also be a severe health problem leading to hypertension or high bp.

The Human circulatory system consists of a muscular four-chambered heart, a network of closed branching blood vessels and blood, the fluid which is circulated. The heart is a  4 chambered muscular organ present in the thoracic cavity in between the lungs. it does not have any bones. The chambers(spaces) of blood are filled with blood.T he muscular action of heart walls pump blood throughout the body through blood vessels. Hence the pumping
