Flashcards in Renal - Anatomy Deck (21):
1

Why is the left kidney rather than the right one harvested for transplantation?

Because the left kidney has a longer renal vein

2

Ureters pass _____ (over/under) the uterine artery and the ductus deferens.

Under (remember: "water [ureters] under the bridge [artery and ductus deferens]")

3

Renal sinus contains

hilum, vessels, perirenal fat, space encapsualted as renal fascia

4

Renal papilla has…

the papillary duct = distal portion of collecting duct

5

As blood goes through the glomerulus ...

its filtered into filtrate, filtrate moves through nephron, at the end of the nephron is the collecting duct -once filtrate gets into papillary duct at renal papilla-- point of no return between filtrate and urine

6

Where are cortical arteries found in the kidney?

The greatest density is in the cortex, but they also can be found in the columns

7

Cortical radiate arteries give rise to:

afferent arterioles, carrying blood into glomerulus

8

Describe renal vein entrapment syndrome

The left renal vein is trapped between the superior mesenteric artery and the aorta, compressing the left renal vein and preventing the return of blood. (The left renal vein gets blood from inferior phrenic, suprarenal, and gonada. Symptoms: hematuria, left flank pain, left testicle pain

9

Blood supply to kidneys is controlled by:

Sympathetic nerves

10

Describe Ureters

tripartite= abdominal, pelvic, intramural

The ureter crosses into the pelvis at the division between internal and external iliac artery, and it passes under uterine artery

11

Lympahtics

common iliac nodes-- lumbar nodes-- cisterna chyli and thoracic duct -from bladder up: bladder drained by external and common iliac nodes and ureter by lumbar nodes and up into thoracic duct and CC

12

What do the ureters pass under?

The uterine artery, or ductus deferens ("water under the bridge")

13

What procedure must be careful in not damaging the ureter and causing a ureteral obstruction or leak?

ligation of uterine vessels traveling in the cardinal ligament

14

What is the 60-40-20 rule?

60% of total body water, 40% ICF, 20% ECF

15

How is blood plasma volume measured?

by radiolabeled albumin

16

How is extracellular blood volume measured?

by inulin

17

The fenestrated capillary endothelium is responsible for what, in the glomerular filtration barrier?

size

18

The fused basement membrane with heparan sulfate is responsible for what, in the glomerular filtration barrier?

negative charge barrier

19

reabsorption = ?

filtered - excreted

20

secretion =

excreted - filtered

21

At what glucose concentration are all transporters in PCT fully saturated? (Tm)

375 mg/dL
