WebAlveoli and Surfactant. Surfactant is made from amphipathic lipoproteins that have one hydrophilic phospholipid, or ‘water-loving” end, and one hydrophobic protein, or “water … WebIt is also the major component of lung elastic recoil, which acts to decrease the size of the alveoli during expiration. 3. The presence of surfactant, a phospholipid produced by the type II alveolar (septal) cells in the alveolar walls, allows alteration of the surface tension of the alveoli and prevents their collapse following expiration. 4.
Type I cells are the larger of the two cell types; they are thin, flat epithelial lining cells (membranous pneumocytes), that form the structure of the alveoli. They are squamous (giving more surface area to each cell) and have long cytoplasmic extensions that cover more than 95% of the alveolar surface. Type I cells are involved in the process of gas exchange between the alveoli and blood. These ce… WebA. inflate the lungs, which forces oxygen molecules into the bloodstream B. deliver oxygen to cells, where it takes part in the reactions of cellular respiration that liberates energy from nutrient molecules and gets rid of carbon dioxide, which maintains the pH of …

WebPneumonia can develop when your immune system attacks an infection in the small sacs of your lung (alveoli). This causes your lungs to swell and leak fluids. Many bacteria, viruses and fungi can cause the infections that lead to pneumonia. Bacteria are the most common cause in adults and viruses are the most common cause in school-aged children. high bridge house hoursWebThe alveoli are the tiny air sacs in the lungs where gas exchange happens.
