Sympathetic stimulation and low blood pressure lead to the release of renin by the juxtaglomerular complex (jgc).
Each nephron has a tubular portion that helps with urine absorption, secretion, and concentration as well as a filtration portion.
The vascular end of the nephron is home to the juxtaglomerular apparatus (JGA). It has populations of three different cell types: granular cells, mesangial cells, and dense macula.
The macular densa and afferent and efferent arterioles make up the juxtaglomerular apparatus, which is located in the glomerular hilum. Its job is to sense the sodium chloride concentration in the filtrate and activate tubuloglomerular feedback, which modifies GFR to control the concentration of tubular sodium and chloride.
