Question
Brush border surface can be taken as a characteristic feature of _______ and this part has a massive amount of _____.
Options:
A .  Proximal convoluted tubule and Mitochondria
B .  Distal convoluted tubule and Thiazide
C .  Henle's loop and Mitochondria
D .  Bowman's capsule and Podocytes
Answer: Option A
:
A
The first part of the tubule, just after the Bowman's capsule, is the proximal convoluted tubule. Brush border cells with multiple microvilli and a massive amount of mitochondria line this tube. This portion of the tubule is one of the largest contributors to electrolyte and water reabsorption. Around 65% of the sodium and water and a little less chloride that were filtered out of the plasmais reabsorbed into the vasa recta in this section.
