Question

All of the following statements are true, except: Question 24 options: 1) Renin is a hormone produced by JG cells 2) JG cells are present in the vasa recta 3) Macula densa cells are present in the ascendinng limb of henle's loop and distal convoluted tubule 4) The JG apparatus play a role in BP regulation

Answer 1

Answer:

2) JG cells are present in the vasa recta.

Explanation:

The vasa recta is a web of the blood capillary which supply blood to the medulla region of a kidney due to its high permeability of solutes and water. It runs parallel to the loop of Henle. It does not composed of the  juxtaglomerular cells (JG cells). The juxtaglomerular cells (JG cells) present in kidney which synthesise and stores enzyme renin. Thus, option 2) JG cells are present in the vasa recta is not a true statement.
