Text Solution

Verified by Experts
The correct answer is:
C

The Juxta Glomerular Apparatus (JGA) is formed by the close contact of:

• The Distal Convoluted Tubule (DCT) cells (specifically the macula densa).

• The Afferent renal arteriole cells (specifically the juxtaglomerular cells).

This region acts as a sensor for blood pressure and sodium levels to regulate the Glomerular Filtration Rate (GFR).
