Histology Flashcards
podocytes
cells in the Bowman’s capsule in the kidneys that wrap around capillaries of the glomerulus and assist with blood filtration
macula densa
specialized cells lining the wall of the distal tubule that detect changes in NaCl concentrations
vasodilate the renal afferent arteriole
secrete renin
PCT vs DCT
PCT is longer, more eosinophilic and cells have brush border
proximal convoluted tubule fx
reabsorb water, ions and organic nutrient
secrete ccreatinine
exchanging hydrogen ions in the interstitium for bicarbonate ions in the filtrate
distal convoluted tubule fx
regulation of potassium, sodium, calcium, and pH
secreting K+ and absorbing Na
reabsorbing Ca2+ in response to PTH
cortical vs juxtamedullary nephrons
cortical have short loop of henle
reduced vasa recta
low GFR
perform excretory regulations of a kidney while JM concentrates or dilutes urea
Ascending loop of henle fx
reabsorb water
descending loop of henle fx
reabsorb Na and Cl ions
vascular pole of renal corpuscle
receives the afferent and efferent arterioles
The urinary pole renal corpuscle
location of the proximal tubule
juxtaglomerular cells/granular cells
specialized smooth muscle cells in the kidney that synthesize, store, and secrete the enzyme renin. They are mainly in the walls of the afferent arterioles
juxtaglomerular apparatus comprises of
macula densa
extraglomerular mesangium
juxtaglomerular cells
the beginning portions of the efferent arteriole
Umbrella cells/facet cells/superficial cells
a single layer of highly differentiated and polarized cells that have distinct apical and basolateral membrane domains demarcated by tight junctions
how do prostatic glands differ from the pancreas and parotid
the alveoli is not densely arranged
a lot of connective tissue and smooth muscle fibers are found between the alveoli
the alveoli are larger and contain large lumens
the walls of the alveoli display folds
which male structure mucosa has longitudinal folds
vas deferens
efferent ducts
