The respiratory system is the body system responsible for breathing and gas exchange. It supplies oxygen to the body and removes carbon dioxide produced by cellular activities. The respiratory system consists of the nose, pharynx, larynx, trachea, bronchi, bronchioles, lungs, and alveoli. Air enters through the nose and travels through these structures to reach the lungs, where gas exchange takes place. The diaphragm assists the lungs during breathing.
