The juxtaglomerular complex:
a. secretes erythropoietin
b. consists, in part, of specialized anteriolar-muscle cells
c. secretes renin
d. consists, in part, of specialized tubular cells of the distal convulated tubule
e. secretes aldosterone
The juxtaglomerular complex works not only under the modality of an endocrine organ that secretes renin but also as a sensor of blood volume and the composition of tubular fluid. Dense macula cells verify the concentration of sodium in the tubular fluid and regulate the glomerular filtration rate as the release of renin by juxtaglomerular cells. Renin catalyzes the hydrolysis of angiotensinogen to produce angiotensin I
