Question

Which of the following is considered the first segment of the renal tubules?

1) Bowman's capsule
2) Proximal convoluted tubule
3) Loop of Henle
4) Distal convoluted tubule

Answer 1

The proximal convoluted tubule (PCT) is the first segment of the renal tubules that receives filtered fluid from Bowman's capsule. It is followed by the loop of Henle and then the distal convoluted tubule (DCT).option 2 is correct.

Step-by-step explanation:

The first segment of the renal tubules in the human kidney is the proximal convoluted tubule (PCT). The filtered fluid collected by Bowman's capsule enters into the PCT, which is known for its tortuous path and the presence of a brush border of microvilli that maximize the absorption and secretion of various solutes.

After the PCT, the fluid then moves into the loop of Henle, which descends into the renal medulla before ascending back up and finally transitioning into the distal convoluted tubule (DCT). The DCT collects the refined filtrate and directs it towards the collecting ducts, which ultimately lead to the formation of urine.The proximal convoluted tubule (PCT) is the first segment of the renal tubules that receives filtered fluid from Bowman's capsule. It is followed by the loop of Henle and then the distal convoluted tubule (DCT).
