Question

in a healthy lung how long does it take oxygen to diffuse from the alveoli to the capillary? ​

Answer 1

Answer:

Capillary transit time:

Transit time of blood in the alveolar capillaries is normally ~0.75-1.0 seconds. A minimum of 0.25 seconds is theoretically enough to fully oxygenate capillary blood. In healthy adults, the minimum capilary transit time is probably about 0.45 seconds.
