| Question | Answer |
|---|---|
| __ is the basic filtering unit of a kidney | nephron |
| Nephron is comprised of a ___ and a vascular supply | renal tubule |
| 85% of all nephron types are ___ | cortical nephron |
| 15% of all nephron types are__ | juxtamedullary nephron |
| kidneys recieve ___% total stroke volume of heart | 20-25% |
| a process by which solutes and fluid are forced through the filtration membrane of a renal corpuscle vias bolld hydrostatic pressure | glomerular filtration |
| components found in the filtrate are due to __ and __ of filtration channels | size and charge |
| entire volume of plasma is filtered every __ minutes or __ times/day | 40 min or 60 times/day |
| Effective filtration pressure is dependent on | glomerular blood hydrostatic pressure |
| blood pressure in the glomerulus is called | glomerular blood hydrostatic pressure |
| __ develops when the filtrate pushes through the walls of the glomerular capsule | capsular hydrostatic pressure |
| walls of glomerular capsule cause __ | resistance |
| fluid already in the renal tubule causes | resistance |
| pressure exerted due to movement of water towards a higher solute concentration | blood colloid osmotic pressure |
