a&p lab exam three Flashcards
waste collected from collecting duct into ____
minor calyx
major calyx drain into ___ which drains into ___
renal pelvis, ureter
difference btwn lung lobes and renal lobes
no physical demarcation between renal lobes
renal columns are found in between ____
renal pyramids
T/F: the collecting duct is part of the nephron
FALSE
the three layers of the kidney (out to in)
renal capsule
cortex
medulla
renal corpusle
glomerulus and Bowman’s capsule
need to know 5 capillaries
peritubular capillaries
-proximal and distal tubules
vasa recta
glomerulus
afferent arteriole
efferent arteriole
nephron loop aka
loop of henle
65% of total filtration reabsorbed in the proximal tubule
juxtaglomerular apparatus
macula densa
granular cells
extraglomerular mesangial cells
granular cell functions
secretes renin, sense increase in pressure
macula dense functions
mod’ed epithelial cells in distal conv tubule, adj to afferent before it enters glomerulus
extraglomerular mesangial cell functions
renal autoregulation, senses blood pressure and increases in salt
cells slides might ask about (renal)
distal tubules
glomerulus
bowman’s space
proximal tubules
The functional units of the kidney are the ___. They’re called ___ if they’re mainly in the cortex. They’re called ___ if they’re in the cortex and medulla, and these have very long Loops of Henle.
nephrons
cortical
juxtamedullary
Blood enters the kidney through the ___ artery. The artery branches into smaller and smaller arteries and arterioles.
renal
Complete the sequence below of blood entering the kidneys:
___ arteriole -> ___ capillaries -> ___ arteriole -> ___ capillaries and vasa recta
afferent -> glomerular -> efferent -> paratubular
Complete the sequence below showing all parts of the nephron:
Glomerular (Bowman’s) capsule -> ___ convoluted tubule -> ___ (both descending and ascending limb) -> ___ convoluted tubule -> ___ duct
proximal -> nephron loop -> distal -> collecting
The renal corpuscle consists of two parts: ___ capillaries and the ___. A portion of the plasma is filtered into the capsular space due to the hydrostatic pressure of the blood.
glomerular
Bowman space
The filtration membrane consists of the following 3 parts: ___, ___membrane, and the ___ (which contain filtration slits.) This filtration membrane filters (selects) by ___ and ___ of a molecule.
glomerular endothelium
basement
podocytes
size
charge
The thin descending limb of the loop of Henle is highly permeable to ___ but not to ___. The thick ascending limb of the loop of Henle is highly permeable to ___ but not to ___.
water
salt
salt
water
Thick section of nephron loop diffuses
Sodium, potassium, chloride
what is the function of seminiferous tubules
produces sperm
