Flashcards in Renal - Anatomy Deck (21):
Why is the left kidney rather than the right one harvested for transplantation?
Because the left kidney has a longer renal vein
Ureters pass _____ (over/under) the uterine artery and the ductus deferens.
Under (remember: "water [ureters] under the bridge [artery and ductus deferens]")
Renal sinus contains
hilum, vessels, perirenal fat, space encapsualted as renal fascia
Renal papilla has…
the papillary duct = distal portion of collecting duct
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
Where are cortical arteries found in the kidney?
The greatest density is in the cortex, but they also can be found in the columns
Cortical radiate arteries give rise to:
afferent arterioles, carrying blood into glomerulus
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
Blood supply to kidneys is controlled by:
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
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
What do the ureters pass under?
The uterine artery, or ductus deferens ("water under the bridge")
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
What is the 60-40-20 rule?
60% of total body water, 40% ICF, 20% ECF
How is blood plasma volume measured?
by radiolabeled albumin
How is extracellular blood volume measured?
The fenestrated capillary endothelium is responsible for what, in the glomerular filtration barrier?
The fused basement membrane with heparan sulfate is responsible for what, in the glomerular filtration barrier?
negative charge barrier
reabsorption = ?
filtered - excreted
excreted - filtered
