Your lungs give oxygen to all the organs and tissues in your body. Oxygen is used throughout the body in chemical reactions to produce energy. The chemical reactions create carbon dioxide as a waste product. Carbon dioxide must then be removed from the body. This is called “gas exchange” (exchanging oxygen for carbon dioxide). The lungs perform both sides of this vital gas exchange for the entire body, both taking in oxygen and removing carbon dioxide.
Your two lungs are located in the chest under the ribs. The lungs are protected and supported by the 12 pairs of ribs, the muscles which lie between the ribs, and the neck muscles. A healthy pair of lungs is soft and spongy. They are made up of elastic tissue that allows them to stretch.
The right lung is divided into three lobes, the upper, the middle and the lower lobes. The left lung is divided into two lobes, the upper and the lower lobes. The trachea (windpipe) delivers inhaled air into the lungs. The lungs themselves are made up of air passageways called bronchi. The airway branches look similar to those on a tree. Each branch becomes smaller and more numerous at each branching. The smallest of these branches end in the tiny gas exchange sacs called alveoli.
