Human anatomy > Respiratory System > Lungs. The lungs are a pair of organs located in the chest that performs respiration. Humans have two lungs; the left lung is divided into two lobes and the right lung is divided into three. The lungs are located in the chest cavity inside the rib cage. They are made of elastic, spongy tissue as they stretch out and constricts while you breathe.
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.
