Pulmonary System

One can listen to the sounds coming from the pulmonary system with the aid of a stethoscope. The pulmonary system is an important part of the circulatory system. It comprises of the part of the circulatory system that supplies blood from the heart to the lungs and then carries oxygenated blood from the lungs to the heart.

Blood containing toxins and waste coming from various tissues and organs in the body is carried by the veins to the heart. These veins enter the heart from the right atrium through the vena cava. Thus the right atrium in the heart mainly comprises of blood that contains toxins, this blood is then pumped into the pulmonary system through the right ventricle. The heart muscles produces contracting motions that regulate the flow of blood pressure.

In the pulmonary system the carbon dioxide rich blood is converted into oxygenated blood .This oxygenated blood coming from the pulmonary system is then transported to the heart. The blood enters the heart through the left atrium and the aorta circulates the oxygenated blood in the entire body. There are one way valves that prevents the backward flow of blood into the heart. Therefore any changes the various parts of the circulatory system can lead to serious complications.
