Lung, in air-breathing vertebrates, either of the two large organs of respiration located in the chest cavity and responsible for adding oxygen to and removing carbon dioxide from the blood. The most important function of the lungs is to take and transfer oxygen from the environment to the bloodstream. In the lungs, air is diverted into smaller and smaller microscopic branches called respiratory bronchioles, which connect to the alveolar ducts. According to the American Lung Association, our lungs breathe in 8,000 to 9,000 liters of air of air daily in order to meet the demand of 8,0000 to 10,000 liters of blood that is pumped in through the heart. © 2005-2021 Healthline Media a Red Ventures Company. Your heart sends deoxygenated blood to the lungs. See a doctor regularly to get health checkups.
