The above image shows the difference in normal alveoli vs. pneumonia. How does the fluid in the lungs affect a variable in Fisk\'s Law? The fluid increases the difference between Po2 in the lungs and in the Po2 in the blood. The fluid increases the surface area within the lungs for diffusion to take place. The fluid causes a thicker distance for oxygen to diffuse from the air to blood. The hemoglobin binds to the fluid in the lungs rather than to oxygen.

Solution

Answer:

the fluid causes a thicker distance for oxygen to diffuse from the air to blood

Explanation:

because in both the lungs the capillaries present on the surface of the alveoli having the same partial pressure of oxygen and carbon dioxide. So partial pressure has no rule. In addition to that, the surface area for exchange of gasses already decreased and thickness of alveoli is same in both lungs. Also, the oxygen is having same atmospheric pressure for both cases.

So the only reason is; the distance is increased between the atmospheric oxygen and capillary blood. So a barrier is created between them, for which oxygen can\'t diffuse easily.

Hope this help!!!
