Human respiratory system, illustration. The trachea (windpipe) leads from the larynx (voice box, in neck) to the lungs (pink) where it splits into the two main bronchi. The bronchi further divide within the lungs, terminating in alveoli (air sacs, lower left). Alveoli are the site of gaseous exchange, where carbon dioxide is removed from the blood and oxygen added. | |
