Lungs: Information and Facts

the lungs

The lungs are located in the chest and are surrounded and protected by the ribs. They are two large spongy organs that get bigger as we breathe in and smaller as we breathe out. The lungs take out the oxygen from the air we breathe in and get rid of carbon dioxide with the air we breathe out. Without lungs, we could not live.

The Larynx
The larynx is the top of the trachea, or windpipe. It forms the bulge in the neck that is called the “Adam’s apple” and contains two vocal cords that vi¬brate and that open and close as we speak or sing.

The Thyroid Gland
The thyroid is a gland located in the front of the neck on both sides of the trachea, or windpipe. It manufactures the hormone that controls how well we break down food into substances that are used for energy and for rebuilding worn-out structures.

The Trachea
The trachea is the windpipe, which extends from the larynx in the neck down to the bronchial tubes in the chest. It carries the air we breathe into and out of the lungs.

The Parathyroid Glands
The parathyroids are four pea-sized glands located in the neck behind the thyroid gland. They make a hormone that controls the way calcium and phosphorus behave in the body. These minerals are important because they help keep bones and muscles in good condition.

The Esophagus
The esophagus is the foodpipe. It extends from the throat down through the chest, and it carries the food and fluids we swallow into the stomach.
