Worked practice questions

A patient with end-stage renal failure typically requires

  1. regular blood transfusions
  2. dialysis or kidney transplant
  3. removal of one kidney
  4. respiratory therapy
Show answer and solution

Correct answer: B. dialysis or kidney transplant

Dialysis (artificial filtering) or kidney transplant. Without filtering, urea, creatinine and fluid build up to toxic levels.

Birds, reptiles, and insects are classified as URICOTELIC because they primarily excrete:

  1. Ammonia (highly toxic, common in fish)
  2. Uric acid (low toxicity, very little water)
  3. Urea (moderately toxic, common in mammals)
  4. Creatinine (a muscle breakdown product)
Show answer and solution

Correct answer: B. Uric acid (low toxicity, very little water)

Uricotelic animals excrete URIC ACID (insoluble paste, low toxicity, requires minimal water). Suits flying birds + desert-dwelling reptiles. Aquatic = ammonotelic; mammals = ureotelic.

The functional unit of the human kidney is called the:

  1. Glomerulus (just the capillary tuft)
  2. Bowman's capsule (just the cup)
  3. Nephron (whole filtering unit)
  4. Loop of Henle (just one segment)
Show answer and solution

Correct answer: C. Nephron (whole filtering unit)

NEPHRON is the functional unit of the kidney. Each kidney has ~1 million nephrons. **Components:** Bowman's capsule (with glomerulus), PCT, Loop of Henle, DCT, collecting duct. ~1 million per kidney.
