The pulmonary capillary plexus is a network of tiny blood vessels located in the lungs, primarily surrounding the alveoli (air sacs) where gas exchange occurs. Its main function is to facilitate the transfer of oxygen from the inhaled air into the bloodstream while allowing carbon dioxide to be expelled from the blood into the alveoli for exhalation. This efficient exchange is crucial for maintaining proper oxygenation of the body and removing metabolic waste gases. The plexus also helps regulate blood flow and pressure within the pulmonary circulation.
