Read the following statements regarding the regulation of kidney function: (A) The Juxta Glomerular Apparatus (JGA) is formed by cellular modifications in the proximal convoluted tubule and the efferent arteriole. (B) A fall in glomerular filtration rate (GFR) can activate the JG cells to release renin. (C) Juxtaglomerular (JG) cells are modified cells of the afferent arteriole. (D) Renin converts angiotensin I to an

Step-by-step solution

Statement (A) is incorrect because the Juxta Glomerular Apparatus (JGA) is formed by cellular modifications in the distal convoluted tubule (DCT) and the afferent arteriole at the location of their contact, not the proximal convoluted tubule (PCT) and efferent arteriole. Statement (B) is correct as a fall in GFR activates the JG cells to release renin. Statement (C) is correct because JG cells are indeed modified cells of the afferent arteriole. Statement (D) is incorrect because renin converts angiotensinogen in t
