The excretory system of human beings consists of the following parts:

  1. A pair of kidneys – filter waste (urea) from blood and produce urine.
  2. A pair of ureters – carry urine from kidneys to the urinary bladder.
  3. Urinary bladder – stores urine until it is released.
  4. Urethra – passes urine out of the body.

Explanation

The question asks you to list parts — so a labelled list with a brief function for each part is ideal for 2 marks. Examiners expect all four components to be named; missing even one can cost half a mark. Mentioning the basic function of each part (filtration, transport, storage, expulsion) adds precision and shows understanding, which is rewarded in board marking.
