The alveoli are also lined with a thin film of moisture. Gases dissolve in this water, making the diffusion path even smaller.
The human gas exchange system - Structure and alveoli
WebWith this in mind, you can see how the alveoli are well adapted for fast diffusion/gas exchange: There are many many alveoli (around 500 million!)- meaning there is a large surface area for diffusion to occur. The alveoli walls (or alveoli epithelium) are one cell thick - therefore there is a short diffusion pathway (short distance). WebThere is an exchange of gases between the alveoli and their surrounding capillary blood vessels. Oxygen diffuses from the alveoli into the blood. Carbon dioxide diffuses from the blood into... how to remove pyrevit
Gas Exchange Flashcards Quizlet
WebGas exchange is the process of swapping one gas for another. It occurs in the alveoli of the lungs. Oxygen diffuses into the capillaries from the air in the alveoli and carbon dioxide diffuses out of the capillaries and into the air in the alveoli. Cell respiration releases energy in the form of ATP so that this energy can be used inside the cell. Web1. small alveoli give larger surface area 2. for diffusion QP Q1a) In the lungs, the alveoli are the site of gas exchange A larger number of small alveoli is more efficient in gas exchange than a smaller number of larger alveoli.
