The four pulmonary veins enter the right atrium of the heart. Introduction: The circulatory system is a double system that means there are two individual systems of blood flow; pulmonary circulation and systemic circulation. The human heart is composed of two separated pumps, the right, and left atrium and the ventricle. The right side helps in pumping deoxygenated blood into the pulmonary circulation, whereas the left side helps in pumping oxygenated blood into the systemic circulation. The great vessels are the crucial vessel that carries oxygenated and deoxygenated blood from the heart to other parts of the body.
