Default renal artery clipping

B
Because low pressur will stimulate contraction of artery myogenic autoregulation and angiotensin will also cause contractin of afferent arteriole

Correct answer is B) Modified smooth muscle cells of the afferent arteriole. Juxtaglomerular apparatus is composed of juxtaglomerular cells, which are modified smooth muscle cells located in the walls of the afferent and efferent arterioles and macula densa cells, which are tall, narrow cells in the distal tubules.
