Worked practice questions

Which yellow pigment, made from the breakdown of heme, gives urine its normal colour?

  1. Urochrome
  2. Melanin
  3. Carotene
  4. Biliverdin
Show answer and solution

Correct answer: A. Urochrome

1. Urine colour comes mostly from the breakdown products of red blood cell destruction. 2. The liver converts heme into water-soluble forms excreted into bile and indirectly into urine. 3. That yellow pigment is urochrome; the other pigments listed colour skin, plants, or bile instead. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 25 "The Urinary System", section Urethra_

Unusually large quantities of urine may point toward which conditions?

  1. Kidney stones or cystitis
  2. Diabetes mellitus or insipidus
  3. Gout or severe dehydration
  4. Anaemia or low blood pressure
Show answer and solution

Correct answer: B. Diabetes mellitus or insipidus

1. Urinalysis often provides clues to renal and systemic disease. 2. Unusually large urine volumes may point to diabetes mellitus, or to hypothalamic tumours causing diabetes insipidus. 3. Stones and cystitis change urine's appearance more than its volume. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 25 "The Urinary System", section Urethra_

A dark tea or cola hue in urine most suggests disease of which organ or its drainage?

  1. The spleen
  2. The pancreas
  3. The liver
  4. The heart
Show answer and solution

Correct answer: C. The liver

1. Liver disease or obstructed bile drainage sends bile pigments into the urine. 2. These impart a dark tea or cola hue. 3. Bright red urine points instead to bleeding from a stone or cancer, a different clue. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 25 "The Urinary System", section Urethra_
