THE PROCESS OF HOW KIDNEYS CARRY OUT THEIR FUNCTION-
- 1. Glomular filtration-
- High BP in glomerulus forces out water, ions, small molecules. Absorbed by cells of Bowman's capsule.
- 2. Tubular reabsorption-
- Substances pass from tubule back into blood, involves active and passive processes.
- 3. Tubular secretion- substances pass from blood into tubule, involves mainly active processes.
