Heart and Lungs - Essay Example lung is a respiratory organ that carries oxygen into the bloodstream from the atmosphere and frees carbon dioxide from the bloodstream into the atmosphere. It is a vital organ that most breathing animals posses. Each of the lungs is situated in either side of the heart close to the spinal column. This is the case among animals with complex life forms such as mammals. The heart and lungs should operate efficiently to ensure enough oxygen reaches the organs. This forms the vascular and the respiratory systems. The lungs hold the air that is taken from the environment before releasing it into the blood. Thereafter, the heart circulates the blood into the entire body. The oxygenated blood flows to the body from the lungs as the deoxygenated blood flows from the body into the lungs (Scharf, Pinsky, & Madger, 2011). The whole process commences at the heart that has the two atria and ventricles. The veins in the right atrium and ventricle receive blood. Concurrently, the deoxygenated blood flows into the heart through the right atrium. The relaxation of the heart muscle then causes the release of blood into the right ventricle from the atrium. Consequently, right ventricle pushes the blood into the Pulmonary Artery via the Pulmonary Valve (Batzel, Kappel, Schneditz, & Tran, 2007). The pulmonary artery then delivers the blood to the lungs where it undergoes purification. After the purification, the oxygenated blood rescinds to the heart through the Left Atrium (Batzel, Kappel, Schneditz, & Tran, 2007). The heart muscles relax again causing the left atrium to send the blood in to the left ventricle. In the end, the heart pushes the blood out delivering it to the entire body. The lungs are the sites of respiratory gas exchange. These gases are oxygen and carbon dioxide. The bronchioles and alveoli deliver blood into the lungs. The bronchioles split from the trachea extending to the lobes of the lungs. It is fundamental to notice that the alveoli are tiny sacs surrounded
