00:01 So, let's wrap up this video series. 00:02 The alveoli are the only place in the lungs where oxygen and carbon dioxide are exchanged. 00:09 The walls of the alveoli and the capillaries are one-cell thick, and that's to allow for diffusion of oxygen into the capillaries and carbon dioxide into the alveoli to be exhaled. 00:21 Now, there's three types of cells in the alveoli, Type I, Type II, and macrophages. 00:27 Surfactant is produced by the Type II cells and reduces surface tension which helps prevent the alveoli from collapsing. 00:35 Now, the walls of the alveoli are destroyed in respiratory diagnoses like emphysema. 00:42 They're penetrated with inflammatory substances and filled with fluid in ARDS, and they collapse due to lack of surfactant in premature infants. 00:52 Thanks for watching our video today.
