What is respiration and gas exchange? - BBC Bitesize

WebApr 7, 2024 · The alveoli are surrounded by a network of blood capillaries. Alveoli transport oxygen from the respiratory system to the bloodstream and remove carbon dioxide from the bloodstream to the respiratory system, allowing the body to exhale. Diffusion allows gaseous exchange through the one-cell-thick alveolar membrane. A pulmonary alveolus (plural: alveoli, from Latin alveolus, "little cavity"), also known as an air sac or air space, is one of millions of hollow, distensible cup-shaped cavities in the lungs where pulmonary gas exchange takes place. Oxygen is exchanged for carbon dioxide at the blood–air barrier between the alveolar air and the pulmonary capillary. Alveoli make up the functional tissue of the mammalian lungs known as the lung parenchyma, which takes up 90 percent of the total lu… richmond london to gatwick airport
