Heart and Lungs - undertake Examplelung is a respiratory organ that carries oxygen into the declivitystream 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 tenderness close to the spinal column. This is the case among animals with complex life forms such as mammals.The center field and lungs should operate expeditiously 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 beforehand 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 solely 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).

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(a) 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 atomic number 18 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 t he lungs. It is implicit in(p) to notice that the alveoli are tiny sacs surrounded
