1

What is located on top of the kidneys?

The two adrenal glands

2

Where are our adrenal glands located?

On top of the kidneys

3

Where are kidneys located?

- Retroperitoneum
- L12 - T3

4

What is calcitriol?

Active form of vitamin D produced in kidney

5

Where is active form of vitamin D produced?

"calcitriol"
In the kidney

6

Hormones secreted by kidney?

EPO
Renin

7

3 developmental stages of kidney?

1. Pronephros - immature
2. Mesonephros
3. Metanephros - adult kidey

8

What is pronephros?

Most immature form of kidney

9

What is metanephros?

Adult form of kidney

10

Layers of kidney from out to in?

1. Capsule
2. Cortex
3. Medulla
4. Hilum

11

What is at tip of medulla?

Papilla that opens into calyx to reach pelvis then become ureter

12

Progress of renal artery?

1. Renal artery
2. Anterior and posterior renal
3. Interlobar arteries: run on side of medullary pyramid
4. Arcuate arteries: come off interlobar arteries
5. InterLOBULAR arteries
6. Afferent arterioles: Feeds glomerulus
7. Efferent arterioles

13

What does the afferent arteriole come off of in kidney?

Interlobular arteries

14

Difference between efferent arterioles in cortex and medulla?

Cortex: form peritubular plexus
Medulla: head to deep medulla form vasa recta to supply loop of henle

15

What is special about juxta medullary glomeruli?

- Efferent arterioles leading from here form vasa recta

16

Does more blood go to cortex or medulla?

Cortex 90%
- Medulla is very susceptible to ischemia

17

What arises from the interlobular artery?

Afferent arteriole

18

Does papillae come before or after calyx?

Before

19

What happens in acute occlusion of interlobular artery?

- Wedge shaped infarct
