Multiple Choice

Which of the following does NOT describe the juxtaglomerular complex?

It consists of the macula densa and juxtaglomerular cells.

It is primarily involved in the production of digestive enzymes.

It helps regulate blood pressure in the kidneys.

It plays a role in the regulation of filtrate formation.

Verified step by step guidance

Step 1: Begin by understanding the juxtaglomerular complex (JGC). The JGC is a specialized structure in the kidney that consists of the macula densa (a group of cells in the distal tubule) and juxtaglomerular cells (specialized smooth muscle cells in the afferent arteriole). Its primary function is to regulate blood pressure and filtrate formation in the kidneys.

Step 2: Analyze the functions of the JGC. The JGC plays a role in the renin-angiotensin-aldosterone system (RAAS), which helps regulate blood pressure. It also monitors sodium concentration in the filtrate and adjusts kidney function accordingly.

Step 3: Evaluate the options provided in the question. The first option correctly describes the components of the JGC. The third and fourth options align with the known functions of the JGC, such as regulating blood pressure and filtrate formation.

Step 4: Identify the incorrect statement. The second option, 'It is primarily involved in the production of digestive enzymes,' does not describe the JGC. Digestive enzymes are produced by organs like the pancreas and stomach, not the kidney.

Step 5: Conclude that the correct answer is the statement that does NOT describe the JGC, which is 'It is primarily involved in the production of digestive enzymes.'
