urinary and reproductive systems Flashcards
(43 cards)
anatomy of the kidney
capped with
adrenal glands
kidneys are located lateral to the vertebral column between the last ______
thoracic and third lumbar vertebrae on each side
three layers of connective tissue layers encapsulate the kidneys
-renal fascia
-perinephric/perirneal fat capsule
-renal capsule
connective tissue around kidneys
renal fascia
Most superficial layer
Dense connective tissue
Surrounds both kidneys and adrenal glands
connective tissue around kidneys
perinephric/ perirenal fat capsule
layer of adipose tissue
connective tissue around kidneys
renal capsule
directly covers the outer surface of the kidney
renal arteries enter at the hilum, renal veins and utters exit at the
hilum
renal cortex
outer regions (granular, reddish-brown)
renal medulla
inner regions (composed of renal pyramids with striped appearance)
renal columns
separate renal pyramids
major and minor calyces
collect urine from renal lobes (a pyramid and surrounding cortical tissue)
right renal vein drains right in
IVC
right gonadal and right suprarenal veins drain right in
IVC
left gonadal and left suprarenal veins drain in ______
left renal vein
urerters
function
Carry urine out of the kidneys to the bladder
layers of connective tissue outside the kidney from outside to inside
renal fascia
perirenal fat capsule
renal capsule
ureters
capable of
peristalsis
ureters
connect to the bladder at an angle that
prevents back flow of urine
ureters exit the kidney at the
hilum
ureters
enter posterior/inferior side of bladder at the ____- in the trigone area
ureteral openings
the -_______ is sensitive to expansion (stretch); when it gets full, signals to empty bladder
trigone
trigone is formed by the _____ and internal urethral orifice
2 ureteric orifices
urinary bladder
_______ help maintain the position of the bladder
peritoneal folds
urinary bladder
detrusor muscle: smooth muscle layer of the bladder
function
involuntary (brain and SC control mechanism of voiding – can be trained)
Bladder expands to fill and contracts to empty – need compliance
Can be very sensitive to bladder irritants and muscular tension
