The pathophysiology instructor will emphasize that the cells of the proximal tubule have a fine, villous structure that increases surface area, allowing for which physiologic function to occur with fluids? Select all that apply.

Complete Question:

The pathophysiology instructor will emphasize that the cells of the proximal tubule have a fine, villous structure that increases surface area, allowing for which physiologic function to occur with fluids? Select all that apply.

A) Aids in reabsorption

B) Location for high-pressure capillary filtration

C) Rich in mitochondria

D) Plays a role in the medullary collecting tubule

E) Supports active transport processes

Correct Option:

The pathophysiology instructor will emphasize that the cells of the proximal tubule have a fine, villous structure that increases surface area, allowing for "aids in reabsorption, richness in mitochondria and supports active transport processes" kind of physiologic function to occur with fluids.

Options: A, C and E

Explanation:

Under 4 segments nephron tubule has been divided out of which proximal convoluted tubule perform a more influential function than distal counterparts. It is the highly coiled segment, which is involved in the renal pelvis in order to become the descending limb of the Henle loop. Whole connection is composed of single layer of epithelial cells resting on a basement membrane.

But the structure of cell varies according to the function of tubule like proximal tubule carry villous structure which allow increment in area of surface and supporting active transport, reabsorption, mitochondria richness. Roughly 65 per cent of filtered load is liable for reabsorbing proximal tubules. Through reabsorbing roughly 80 per cent of processed bicarbonate, it plays a key role in controlling acid-base equilibrium.
