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 main organ of the respiratory system is the lungs. The diaphragm is a muscle located underneath the heart and lungs that contracts to pull air into the lungs and relaxes to force air out of the lungs. When the air enters the lungs, it travels through the bronchi to tiny air sacs called alveoli.he main organ of the respiratory system is the lungs.
