1: Anatomy of Renal System - Khan Flashcards
_____ kidney is usually 1.5-2 cm lower
right kidney
transpyloric plane passes through upper part of l. kidney
where are the kidneys located?
retroperitoneal, either side of vertebral column between T12-L3
occupied by renal pelvis and calyces
renal sinus
location of ureters
retroperitoneal, about 25 cm long, descend vertically anterior to transverse processes of L2-L5
three main sources of blood to ureters
renal a.
superior vesical a.
common illiac or aorta
blood supply to bladder
superior and inferior vesical a.
vesical venous plexus drains into internal iliac
3 parts of male urethra
prostatic urethra
membranous urethra
penile urethra
15-20 cm long compared to 2-6 cm long in female
lies between neck of bladder and urogenital diaphragm
prostate gland
blood supply to prostate
internal pudendal
inferior vesical
middle rectal
prostatic venous plexus drains into internal iliac vv.
perirenal v. pararenal fat
perirenal is between renal fascia and fibrous capsule of kidney
pararenal fat is around the renal fascia
3 areas where ureter constricted
- at renal pelvis
- crossing the iliac aa.
- at entering bladder
blood supply to suprarenal glands
superior suprarenal from inf. phrenic
middle suprarenal from aorta
ifneriro suprarenal from renal a.
area where mucous membrane firmly attached to muscle in bladder
urinary trigone
place where infections often start in bladder
describe opening of ureter into bladder
oblique entry, acts as sphincter that prevent retro movement of urine
lobe that increases in size with BPH
median lobe - pushes on urethra as it passes through prostate
