Q: In human beings, excretory products in the form of soluble nitrogen compounds are removed by the _______ in the kidneys.
  • A. Mitochondria
  • B. Nutrition
  • C. Nephrons
  • D. Nucleus
Correct Answer: Option C - In human beings, excretory products in the form of soluble nitrogen compounds are removed by the nephrons in the kidneys. Each of our kidney is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus and a renal tubule. The nephrons work through a two-step process : the glomerulus filters blood, and the tubule returns needed substances to our blood and removes wastes.
