Multiple Choice

Which of the following does NOT describe the juxtaglomerular complex?

It is located in the renal cortex near the glomerulus.

It helps regulate blood pressure and filtrate formation.

It secretes insulin to regulate blood glucose levels.

It contains macula densa and granular cells.

Verified step by step guidance

Understand the role of the juxtaglomerular complex (JGC): The JGC is a specialized structure in the kidney that plays a critical role in regulating blood pressure and filtrate formation. It is located in the renal cortex near the glomerulus and contains macula densa cells and granular cells.

Review the components of the JGC: The macula densa cells monitor sodium concentration in the filtrate, while granular cells secrete renin, an enzyme that helps regulate blood pressure through the renin-angiotensin-aldosterone system.

Identify the incorrect statement: The JGC does not secrete insulin. Insulin is secreted by the beta cells of the pancreas to regulate blood glucose levels, which is unrelated to the functions of the JGC.

Compare the correct functions of the JGC with the provided options: The JGC is involved in blood pressure regulation and filtrate formation, and it contains macula densa and granular cells. These functions align with the correct descriptions provided in the options.

Conclude that the statement 'It secretes insulin to regulate blood glucose levels' is incorrect because it describes a function of the pancreas, not the juxtaglomerular complex.
