location of kidneys
- between the abdominal wall and peritoneum
- between T12 and L3
-
retroperitoneal
behind the peritoneum
-
Which kidney is lower? Why?
right; right liver lobe is larger
-
locate:

renal capsule
renal column
renal pyramid
5, 9, 17, 1
-
locate:
renal papillae
major calyx
minor calyx
renal pelvis
ureter
16, 15, 14, 6, 7
-
locate:
renal medulla
renal cortex
renal sinus
-
proximal/distal convoluted tubules, descending/ascending loops of Henle, collecting duct, Bowman's capsule, glomerulus, afferent/efferent arterioles
-
What type of cells line the parietal layer of the glomerular capsule?
simple squamous
-
podocytes
- modified simple squamous;
- have pedicels (foot processes) that wrap around glomerular capillaries;
- found in visceral layer of Bowman's capsule
-
7 components of a nephron:

- 2) proximal convoluted tubule
- 3) distal convoluted tubule
- 4) descending loop of Henle
- 5) ascending loop of Henle
- 6) collecting duct
- 7) papillary duct
-
5 components of a renal corpuscle:
- 1) Bowman's capsule
- 2) glomerulus
- 3) afferent arteriole
- 4) efferent arteriole
