Urinary System Exam Questions Questions
Question 1 of 5
Metabolic contribution of urinary system is:
Correct Answer: D
Rationale: Kidneys synthesize calcitriol, secrete erythropoietin, and perform gluconeogenesis all apply. This encompasses metabolic roles, vital for homeostasis, contrasting with single contributions.
Question 2 of 5
In glomerulus afferent blood vessel is 'arteriole' while efferent is:
Correct Answer: B
Rationale: Efferent vessel is an arteriole, not venule, capillaries, or artery. This specifies glomerular vasculature, key for pressure, contrasting with venous or capillary terms.
Question 3 of 5
Glomerular filteration occurs because of;
Correct Answer: A
Rationale: Hydrostatic pressure drives glomerular filtration, not colloidal (opposes), osmotic (retains), or none. This identifies filtration force, key for GFR, contrasting with opposing pressures.
Question 4 of 5
What portion of the nephron extends into the medulla?
Correct Answer: A
Rationale: Nephron loop (loop of Henle) extends into medulla, not PCT, DCT (cortex), or papillary duct (collecting). This locates medullary segment, critical for concentration, contrasting with cortical parts.
Question 5 of 5
Fibrous connective tissue that surrounds each kidney is the:
