The cells of the proximal convoluted tubule are specialized for tubular reabsorption because they have:
A)a greater blood supply nearby
B)microvilli to increase their surface area
C)more glomerular capillaries surrounding them
D)cilia to sweep useful materials in

Question

Quizplus · Accepted Answer

The presence of microvilli increases the surface area of the proximal convoluted tubule, which allows for more efficient reabsorption of materials such as glucose, amino acids, and ions from the filtrate back into the bloodstream. A greater blood supply nearby (A) and more glomerular capillaries surrounding them (C) may be important for filtration but are not specific to reabsorption. Cilia (D) are not present in the proximal convoluted tubule.
