final lecture renal Flashcards
detrusor muscle?
muscularis muscle of bladder. contracts to help empty bladder.
where does filtration occur in renal system?
glomerular filtration barrier
3 parts of glomerular filtration barrier?
fenestrated capillary endothelium, basal laminae, filtration slit pores
juxtaglomerular cells?
modified smooth muscle cells in tunica media of afferent arteriole that contains renin
function of renin?
control blood pressure by raising BP
macula densa
portion of DCT as it approaches afferent arterioles (vascular pole) of nephron. cells monitor the sodium concentration of the tubular fluid
what happens to cells in distal tubule?
simple cuboidal become narrower, taller, and more densely packed and nuceli appeared crowded
macula densa is apart of what?
juxtaglomerular apparatus
what are podocytes?
epithelial cells that line visceral layer of bowmans capsule
pedicels
foot processes that are in direct contact with basement membrane of capillary endothelial cells. primary processes give rise to!
what is inbetween spaces of pedicles?
filtration slits pores
ureter mucosa?
urothelium
muscularis of ureter?
2 layers of smooth muscle
nephron?
consists of renal corpuscle and a tubule system. fundamental and structural unit of kidney
renal corpuscle to urinary pole?
PCT to PT to loop of henle to DT to DCT to CT to CD
