Urinary System Multiple Choice Questions Questions
Question 1 of 5
Fibrous connective tissue that surrounds each kidney is the:
Correct Answer: D
Rationale: Renal capsule (fibrous) encases kidney not cortex, hilum (entry), medulla, or pyramids (inner). This identifies protective layer, vital for structure, contrasting with regions.
Question 2 of 5
The functional unit of the kidney is called ________.
Correct Answer: C
Rationale: Nephron is the functional unit not hilus (entry), corpuscle (part), or capsule (subset). This defines renal physiology, critical for function, contrasting with structural parts.
Question 3 of 5
Renin is released in response to ________.
Correct Answer: B
Rationale: Decreased BP triggers renin not increased BP, ACE (downstream), or diuretics (effect). This initiates RAAS, key for pressure regulation, contrasting with high-pressure states.
Question 4 of 5
The primary function of the ascending loop of Henle in the kidney is?
