What are the conditions that facilitate diffusion between alveoli and blood capillaries?
Answers
Answer:
The partial pressure of carbon dioxide in the capillaries is much higher than that in the alveoli. This means that net diffusion occurs into the alveoli from capillaries. The carbon dioxide can then be exhaled as the partial pressure in the alveoli is also higher than the partial pressure in the external environment.
Answer:
It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli. The walls of the alveoli actually share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream.
The main factors include:
Membrane thickness - the thinner the membrane, the faster the rate of diffusion. ...
Membrane surface area - the larger the surface area, the faster the rate of diffusion. ...
Pressure difference across the membrane.
Diffusion coefficient of the gas.
