Questions On The Urinary System Questions
Question 1 of 5
The right kidney is slightly lower because ________.
Correct Answer: A
Rationale: Liver displaces right kidney lower not heart (left), size, or ribs (protection irrelevant). This explains asymmetry, key for anatomy, contrasting with other causes.
Question 2 of 5
Juxtaglomerular cells combine with _______ cells to form the juxtaglomerular apparatus in the kidney.
Correct Answer: A
Rationale: JG cells and macula densa form the JGA not pelvis, nephron (whole), or sinus. This specifies RAAS structure, critical for pressure, contrasting with broader terms.
Question 3 of 5
The primary function of the descending loop of Henle in the kidney is?
Correct Answer: B
Rationale: Descending loop reabsorbs water osmotically not Na+, H+, or K+ (ascending/DCT). This specifies concentrating role, critical for gradient, contrasting with ion processes.
Question 4 of 5
Which of the following is not considered a loop diuretic?
Correct Answer: C
Rationale: Chlorthiazide is a thiazide not loop diuretic (others are). This distinguishes diuretic class, critical for pharmacology, contrasting with loop agents.
Question 5 of 5
Capillary hydrostatic pressure during filtration is built in the glomerulus as
Correct Answer: D
Rationale: Efferent arteriole's narrowness raises glomerular pressure not Bowman's size/shape or afferent narrowness. This explains filtration pressure, key for GFR, contrasting with structural myths.
