Flashcards in Histology And Blood Vessels Deck (11):
1
What are renal corpuscles?
Bowman's capsule and glomerulus
2
Name the poles of the renal corpuscle
Vascular
Urinary
3
Name the 4 parts of the loop of Henle
Pars recta
Thin descending limb
Thin ascending limb
Thick ascending limb
4
Describe the thin limbs of the loop of Henle
Simple squamous
No active transport
Looks like a capillary with no RBCs
No brush border
5
Describe the thick ascending limb
Best seen in the medulla
Simple cuboidal epithelium
No brush border
Active transport occurs
6
Describe the DCT
Found in the cortex near to 'parent' glomerulus
Contains numerous mitochondria
No brush border
Large lumen than the PCT
7
What does the juxtaglomerular apparatus consist of?
Macula densa (of DCT)
Juxtaglomerular cells
Extraglomerular mesangial cells
8
Describe the ureter
Muscular tube
2 layers of smooth muscle in upper 2/3
Lower 1/3 of ureter has 3 layers of smooth muscle
Transitional epithelium
9
Describe the blood flow from the aorta to the glomerulus
Aorta > renal artery > segmental artery > interlobar artery > arcuate artery > cortical radiate artery > afferent arteriole > glomerulus
10
Describe the blood flow from efferent arteriole to the IVC
Efferent arteriole > peritubular capillaries (+ vasa recta) > cortical radiate vein > arcuate vein > interlobar vein > renal vein > IVC
