Introduction

The circulatory system comprises of heart and blood vessels. The blood which is devoid of oxygen and carries carbon dioxide is the impure or deoxygenated blood. This blood reaches the heart where is transferred to the lungs through the pulmonary artery. The oxygen-rich blood is transferred to the heart from the lungs via the pulmonary vein and the heart pumps out the oxygenated blood to all parts of the body.
