Kidney Flashcards

1
Q

Function of kidney

A
  • filtrate
  • retroperitoneal organ (behind the peritoneum but attached to the abdominal wall)
  • located T12- L3 (left kidney is higher b/c there’s a liver on the right side of the kidney) (top part of the kidneys are protected by the ribs)
  • muscles: psoas major m., quadriaous lambarum

16
Q

Visceral layer

A
  • podocytes (modified, branching epithelial layer)

- involved in filtration process

17
Q

Filteration membrane

A
  • basement membrane
  • podocytes (foot process)
  • filtration slits (opening between the foot process) on the basement membrane
  • fendestrated endothelium of glomerular capillary
18
Q

Renal corpuscle

A
  • glomerulus AND glomerular capsule

- in the cortex

19
Q

Renal Tubules

A
  • PCT (cortex)
  • Loop of Henle (pyramids)
  • DCT (cortext)
20
Q

Collecting Tubule

A

NOT part of nephron

21
Q

Juxamedullary

A

close to medullary/pyramids

22
Q

Cortical

A

close to cortex

23
Q

Ureter

A
  • passes over the pelvic brim

- next to the bifrication of the common iliac arteries

24
Q

Ureter blood supply:

A
  • major (renal artery)
  • Gonadal artery (testicular/ovarian artery)
  • Abdominal aorta
25
Q

urinary bladder

A
  • pelvic organ

- rugae throughout the bladder except the trigone

26
Q

Urinary bladder Tissue

A

Transitional epithelium (stratified) b/c it is able to change shape depending on whether it’s full (cells flatten) or empty (dome shaped)

27
Q

Urinary bladder muscle:

A

Detrusor muscle

28
Q

Adult vs Children

A
  • adult: pelvic organ
  • children: intraabdominal organ b/c pelvis isn’t grown –> very be careful b/c they’re more prone to get it ruptured-think of seatbelts! –> starts moving down at age 6 and continuous until puberty
29
Q

Trigone

A
  • posterior wall, smooth
  • 3 openings (ureter x2 and urethra
  • where infxn happens!
30
Q

Urethra: male vs female

A
  • males have significantly longer urthera (less prone to UTI compared to females)
  • males: urthera needs to get through the prostate gland
  • females: uterus is in front of bladder and urethra
31
Q

Hroseshoe kidney

A
  • kidney starts as pelvic organ (unlike bladder) and makes it’s way up
  • inferior poles of the kidneys fuse together and gets stuck around L3-L5
32
Q

Renal Calculus

A
  • obstruction of urine outflow

- referred pain

33
Q

Referred pain

A

visceral pain as somatic sensation d/t pathway of the information going to the CNS so they c/o low back pain for kidneys

34
Q

PKCD

A
  • genetic disorder

- adult onset
