WebPulmonary surfactant is a surface-active complex of phospholipids and proteins formed by type II alveolar cells. The proteins and lipids that make up the surfactant have both hydrophilic and hydrophobic regions. By adsorbing to the air-water interface of alveoli, with hydrophilic head groups in the water and the hydrophobic tails facing towards the air, the … WebThey increase the surface area of the intestines to allow digested food to be efficiently absorbed into the bloodstream and delivered to cells around the body. Villi are filled with blood... how does vector presence cause infectionWebReinflation of the alveoli following exhalation is made easier by the surfactant, which reduces surface tension in the thin fluid lining of the alveoli. The fluid coating is produced by the body in order to facilitate the transfer of gases between blood and alveolar air, and the type II cells are typically found at the blood–air barrier.

Each lung contains millions of these sacs. The small round alveoli allow for an amazingly large surface area for this gas exchange to take place. Therefore, the greater the surface area, the more gas exchange can occur.

WebBecause there are so many alveoli (~300 million per lung) within each alveolar sac and so many sacs at the end of each alveolar duct, the lungs have a sponge-like consistency. This organization produces a very large surface area that is available for gas exchange. The surface area of alveoli in the lungs is approximately 75 m 2. This large ...
