Lungs are vital paired organs located in the chest, which perform respiration. Respiration is needed for cell metabolism, balancing blood ph, and maintaining body temperature. It is important to illustrate what lungs are and how they function, so that the Diseases and Disorders talked about in the future are more understandable.
The main function of the lungs is to bring oxygen into the blood stream by inhaling breaths of air. A person can inhale air through the nose or the mouth. Everyday the average person takes in 23,000 breaths of air. This turns out to be about a pint of air a minute. The air we breathe contains oxygen, which humans need to survive. Once the oxygen is in the blood it distributes it to all of the cells throughout the body. Without oxygen the body’s cells could not continue to exist. After oxidization takes place the lungs exhale the gas Carbon Dioxide. Carbon Dioxide is an unnecessary, waste gas that body cells discharge.
Above is an illustration of the structure of the Lungs. The basic structure consists of the Trachea, which is the windpipe, and the lungs. The Trachea takes the air from the mouth and nose and brings it into the lungs. There are two branches of the Trachea the Left and Right Bronchus. At the end of these branches are tiny air sacs that inflate and deflate during respiration. These tiny sacs are called Alveoli.
So that is just a small overview of the lungs and how they function.
