Inferior vena cava
14. What are the two main parts of the nephron? Renal corpuscle
Renal tubule
15. This part of the nephron filters fluid from the blood. Renal corpuscle
16. This part of the nephron alters the concentration of Renal tubule
the filtrate using reabsorption and secretion.
17. What are the two parts of the renal corpuscle? Glomerulus
Glomerular capsule

22. What are the three regions of the renal tubule? 1. Proximal convoluted
tubule (proximal, closest
to renal corpuscle)
2. Nephron loop
3. Distal convoluted tubule
(distal, farthest from renal
corpuscle)
23. -Consists of cuboidal cells with dense microvilli that The proximal convoluted
form brush border. tubule
-Functions in reabsorption and secretion
-Confined to cortex

25. What are the two limbs of the nephron loop? 1. Descending limb--thin
limb
2. Ascending limb--thick
limb
26. Distal convoluted tubule
