The robust pump of the heart and the blood vessels are used in this process(Nader et al., 2019). The four-chambered heart in the chest comprises the right and left atria and ventricles. Therefore, the two primary circuits are the pulmonary and systemic blood circulation circuits. Pulmonary Circulation Through the superior and inferior vena cava, carbon dioxide-rich blood deoxygenated to the heart from the body reaches the right atrium. During cardiac contractions, the tricuspid valve allows deoxygenated blood to enter the right ventricle. As the proper ventricle contracts, blood that has lost its oxygen is pushed into the pulmonary artery. The pulmonary artery divides into smaller blood arteries called arterioles that go to the lungs(Nader et al., 2019). Blood circulates via a network of tiny capillaries that surround the air sacs called alveoli. While carbon dioxide diffuses out of the blood and into the alveoli, where it may be evacuated, oxygen from the air we breathe diffuses over the flimsy alveolar walls and into the blood in the al
