Nephron Flashcards

1. What structure in the nephron filters blood plasma?

2. What surrounds the glomerulus and collects filtrate?

3. What vessel brings blood into the glomerulus?

4. What vessel drains blood away from the glomerulus?

5. What structure connects Bowman's capsule to the loop of Henle?

6. What is the main function of the proximal convoluted tubule?

7. What structure creates a concentration gradient in the medulla?

8. What is the function of the descending limb of the loop of Henle?

9. What is the function of the ascending limb of the loop of Henle?

10. What structure connects the loop of Henle to the collecting duct?

11. What hormone acts on the distal tubule to increase sodium reabsorption?

12. What hormone increases water reabsorption at the collecting duct?

13. What is the specialized structure regulating blood pressure in the nephron?

14. What hormone is secreted by the juxtaglomerular apparatus?

15. What capillary network surrounds the proximal and distal tubules?

16. What capillaries surround the loop of Henle in the medulla?

17. What is the primary driving force for glomerular filtration?

18. What is the average glomerular filtration rate in healthy adults?

19. What type of pressure opposes glomerular filtration?

20. What ion is heavily reabsorbed in the thick ascending limb?

21. What part of the nephron is impermeable to water?

22. What happens to glucose filtered at the glomerulus in a healthy nephron?

23. What happens when blood glucose exceeds the reabsorptive capacity?

24. What process moves substances from blood into nephron tubules?

25. What process moves substances from nephron tubules back into blood?

26. What part of the nephron adjusts final urine concentration?

27. What is the filtrate called when it enters the proximal tubule?
