Questions On The Urinary System Questions
Question 1 of 5
The kidneys are:
Correct Answer: D
Rationale: Kidneys regulate blood volume (water balance), pressure (RAAS), and pH (H+ excretion) all apply. This encompasses renal functions, vital for homeostasis, contrasting with single roles.
Question 2 of 5
Diabetes insipidus or diabetes mellitus would most likely be indicated by ________.
Correct Answer: B
Rationale: Polyuria (excess urine) marks diabetes insipidus (ADH lack) and mellitus (glucose diuresis) not anuria (none), oliguria (low), or none. This links conditions to output, key for diagnosis, contrasting with reduced flow.
Question 3 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 4 of 5
What signal causes the heart to secrete atrial natriuretic hormone?
Correct Answer: A
Rationale: Increased BP triggers ANP release not decreased BP or Na+ changes alone. This links pressure to natriuresis, critical for volume control, contrasting with low-pressure signals.
Question 5 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.
