WebThe alveoli are sites where air is exchanged in the lungs. Simple squamous epithelial cells in the alveoli allow oxygen from the air to enter the blood in the capillaries of the lung. Carbon dioxide, a waste product, passes across the epithelium of the alveoli to be removed from the body. Simple squamous epithelium lines the air sacs, or ... WebGas exchange occurs at the alveoli in the lungs and takes place by diffusion. The alveoli are surrounded by capillaries so oxygen and carbon dioxide diffuse between the air in the …

WebApr 4, 2024 · Smoking destroys the tiny air sacs, or alveoli, in the lungs that allow oxygen exchange. When you smoke, you are damaging some of those air sacs. Alveoli don’t grow back, so when you destroy them, you have permanently destroyed part of your lungs. When enough alveoli are destroyed, the disease emphysema develops. http://histologyguide.com/EM-view/RD-182-alveoli/17-photo-1.html

WebTo determine the function of CLDN18 in the alveolar epithelium, CLDN18 knockout (KO) mice were generated and studied by histological, biochemical, and physiological approaches, in addition to whole-genome microarray. Alveolar epithelial barrier function was assessed after knockdown of CLDN18 in isolated lung cells. WebGas exchange occurs in the alveoli which are found in the lungs.
