About 30 alveoli open out of each alveolar duct, which leads from a respiratory 'bronchiole. The alveolar walls, which separate alveoli, contain capillaries. The alveoli are lined by a single layer of 'pneumocytes. which thus form a very thin layer between air and blood so that exchange of oxygen and carbon dioxide is normally rapid and complete. Children are born with about 20million alveoli. The adult number of about 300 million is reached around the age of eight.A thin-walled air sac that is found in clusters in the lungs and that is the site of gas exchange.A tiny hollow or compartment. This term typically describes a socket in the bone where a tooth is anchored or an air-filled space within the lung.
