 Urine is formed based on three steps that will be discussed : -Filtration -Re-absorption -Secretion - wastes are filtered from the blood by the kidneys.

Osmoregulation and Excretion Water Balance and Waste Disposal Excretory Systems.
EXTERNAL ENVIRONMENT Mouth Food CO 2 O2O2 ANIMAL Digestive system Respiratory system Circulatory system Urinary system Heart Interstitial fluid Body cells.
7.5.  Filtration: movement of fluids from blood into the Bowman’s Capsule  Reabsorption: transfer of essential solutes and water from nephron back into.
