WebThe lung is a respiratory organ responsible for gaseous exchange between air and blood. The lung contains many branching airways, or bronchioles, which end in small cup shaped structures called alveoli, where gaseous exchange occurs. These many branching airways give the lung a massive surface area over which gaseous exchange can take place. WebYour bronchi work with your respiratory system to help you breathe. When you breathe: Air passes from your mouth to your trachea. Your trachea divides into your left and right bronchi. The bronchi carry air into your lungs. At the end of the bronchi, the bronchioles carry air to small sacs in your lungs called alveoli.
