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

11

Describe Wilm's tumour

Nephroblastoma
Commonly occurs in children
25% associated with developmental abnormalities
Highly responsive to treatment
Large abdomen, loss appetite, abdominal pain, fever, nausea
