The intercostal muscles are a group of 22 pairs of tiny muscles found between the ribs. These muscles play a vital role in the movement of the chest during breathing. They also help to solidify the thoracic region and protect the lungs.
The lungs are designed to absorb oxygen from the air and transfer it into the bloodstream. The lungs are found inside the chest and are protected by the rib cage. Between the ribs are muscles that are essential for breathing. The most important muscle of breathing is called the diaphragm. It is dome shaped and lies below the lungs separating them from the abdomen. Two thin layers of tissue called the pleura cover each lung and the inside of the rib cage. These layers or membranes, slide back and forth over each other as we breathe.
