what part of the juxtaglomerular apparatus senses sodium levels in the urine
macula densa (A in diagram)
They sense low sodium levels in the urine of the DCT and secrets prostaglandin in response. This prostaglandins trigger the release of renin. How does low sodium levels equate low blood pressure? That’s because filtration at the renal corpuscle level is directly related to the blood pressure inside the glomeruli. Low blood pressure=> low filtration => low solutes (like Na+) in the filtrate/urine.
what part of the juxtaglomerular apparatus senses synthesizes and releases renin
extra glomerular cells (B in diagram)
(aka granular cells)
