WebThe exchange of gases occurs between the alveoli and blood in the capillaries. that supply the lungs. The alveoli are adapted to provide a very large surface area for gaseous … Webmillions of these sacs. • The small round alveoli allow for an amazingly large surface area for this gas exchange to take place. Remember, the blood capillaries must be in contact with the respiratory surface for gas exchange to take place. Therefore, the greater the surface area, the more gas exchange can occur.

WebJul 30, 2024 · Gas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up. External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs. WebGas exchange is possible in respiratory bronchioles and alveolar ducts, but mainly occurs in the alveoli. The alveolar ducts have a few elastic and collagen fibers to support them. Tiny smooth muscle bundles in respiratory bronchioles and alveolar ducts can control air movement in acini. chip maker for self driving cars
