Basic Renal Processes
| Question | Answer |
|---|---|
| What is a Nephron? | microscopic Filtration unit |
| What are the Vascular Components of the Nephron? | Afferent Arterioles, Glomerulus, Efferent Arterioles, Peritubular Capillaries, Venules |
| What are the Tubular Components of the Nephron? | Glomerular Capsule, Proximal Convoluted Tubule, Loop, Distal Convoluted Tubule, Collecting Ducts |
| What 3 processes dictate the composition & volume of urine? | 1. Glomerular Filtration; 2. Tubular Reabsorption; 3. Tubular Secretion |
| What is Glomerular Filtration? | Fluid passage into Glomerulus Capsule |
| What typr of filtration does Glomerular Filtration provide? | selectively filtered based upon SIZE |
| What is Tubular Reabsorption? | molecules SELECTIVELY removed from Tubules --> Peritubular Capillaries |
| What is the significance of Tubular Reabsorption? | conservation of important molecules |
| What is Tubular Secretion? | molecules transferrred from Peritubular Capillaries --> Tubules of the Nephron = blood --> urine |
| What is the significance of Tubular Secretion? | Selectively places wastes into the urine |
