The Juxtaglomerular Complex Adjusts Glomerular Filtration Rates by Secretion of Which

Question

The juxtaglomerular complex adjusts glomerular filtration rates by secretion of which hormones?
A) vasopressin and erythropoietin
B) oxytocin and vasopressin
C) renin and erythropoietin
D) gastrin and insulin
E) glucagon and renin

Accepted Answer

The juxtaglomerular complex secretes renin, which plays a crucial role in regulating glomerular filtration rates. Renin acts on the renin-angiotensin-aldosterone system to increase blood pressure and stimulate the reabsorption of sodium and water in the kidneys. Erythropoietin is also secreted by the juxtaglomerular complex, but it primarily regulates red blood cell production, not glomerular filtration rates. Vasopressin is produced by the hypothalamus and regulates water balance, while oxytocin is involved in uterine contractions and lactation. Gastrin and insulin are produced by the stomach and pancreas, respectively, and are not involved in kidney function.
