What to Focus On

  • Nitrogenous wastes include ammonia, urea, and uric acid.
  • Ammonia is most toxic; uric acid is least toxic.
  • Ammonotelism, ureotelism, and uricotelism are based on the main nitrogenous waste excreted.

  • Kidneys are located near the dorsal inner wall of the abdominal cavity.
  • Each kidney has nearly one million nephrons.
  • Nephron is the structural and functional unit of kidney.

  • Filtration, reabsorption, and secretion are the three steps of urine formation.
  • GFR is the amount of filtrate formed by kidneys per minute.
  • Almost all plasma constituents except proteins pass during ultrafiltration.

Common Mistakes to Avoid

Glomerular filtration is the same as urine formation.

The glomerulus alone is the renal corpuscle.

The filtrate contains proteins in normal filtration.
