Verified
The juxtaglomerular apparatus is composed of
A) juxtaglomerular cells and the macula densa.
B) podocytes and juxtaglomerular cells.
C) the macula densa and the filtration membrane.
D) juxtaglomerular cells and the filtration membrane.
E) glomerulus and Bowman capsule.
Juxtaglomerular Apparatus
The juxtaglomerular apparatus is a specialized structure in the kidney that plays a key role in regulating blood pressure and filtrate formation by managing the release of renin.
Juxtaglomerular Cells
Specialized cells in the kidneys that help regulate blood pressure by secreting renin in response to blood pressure changes.
Macula Densa
Cells of the distal convoluted tubule located at the renal corpuscle and forming part of the juxtaglomerular apparatus.
- Elucidate on the architecture and operative unit of the kidney, with a focus on the juxtaglomerular complex.

Final Answer :
A
Explanation :
The juxtaglomerular apparatus is composed of juxtaglomerular cells, which are specialized smooth muscle cells in the walls of the afferent arteriole, and the macula densa, which is a group of specialized cells in the distal convoluted tubule. These components work together to regulate blood pressure and the filtration rate of the kidneys.
