The lungs are part of the respiratory system which is made up of a variety of tissues and organs that work together to bring oxygen into your body. Every cell in your body requires oxygen to survive. Without enough oxygen, the cells begin to die.
As you breathe in oxygen and other gases in the air, the lungs separate the oxygen and send it off to the blood stream. The blood carries the oxygen to all of the cells in the body. The cells then exchange the oxygen for carbon dioxide, which is carried back to the lungs as waste gas. It is then exhaled from your lungs and your body in the breathing process.The lungs are made up of two sections. The right lung has three lobes or sections, while the left only has two, which leaves room in the body for the heart. These lobes work together to bring oxygen to the cells and then getting rid of the waste gas at the end of the breath cycle.The respiratory system is an intricate system that works hard to make your body function at its optimal level. Unfortunately, the lungs are vulnerable to anything that gets through its filtering system, which includes the nostrils, mouth, throat, and bronchial tubes. When this happens, the lungs are more susceptible to sickness, include the common cold, bronchitis, and pneumonia.
