Lung Anatomy

What is breathing? Although it appears to very simple question, the answer to this question is not that simple. Understanding the lung anatomy will be useful in answering this question in detail. It is a well known fact that breathing is important for your body. The oxygen that is inhaled by the process of breathing is converted into energy that is essential not just for regular functions.

According to the lung anatomy, the oxygen that is breathed in with the air is pulled in through the trachea. A normal individual will have two lungs of slightly varying sizes that is evident if you see an image of the lung anatomy. The image will also reveal bronchi that are airway passages that facilitate the movement of air from the trachea into the lungs.

There is a complex pattern of bronchioles that can be seen with air sacs in a normal lung anatomy and these bronchioles end into alveoli. The wall of these alveoli is so thin that oxygen from the air easily passes through the membrane of the alveoli and is circulated in the entire body by the blood stream. Similarly when you breathe out, the carbon dioxide from the blood is exhaled through the alveoli into the lungs and exhaled from the body. The functioning of the lungs is affected by various conditions like bronchitis and emphysema.
