Nephritis refers to the inflammation of the kidneys, commonly involving the glomeruli.

As a part of the inflammatory response, the blood vessels dilate and their vascular permeability increases.

This increased permeability allows fluid to leak out from the blood capillaries and move into the surrounding interstitial spaces.

The accumulation of fluid in these interstitial spaces results in edema (swelling) of the kidney tissues, which is a primary characteristic of the inflammation.

Answer: movement of fluid from blood into interstitial spaces.
