cortical nephrons - Correct Answers -85% of nephrons; almost entirely in cortex
juxtamedullary nephrons - Correct Answers -nephrons with well-developed loops of
Henle that extend deeply into the renal medulla
, urine concentration
filtration - Correct Answers -non-selective process
PRESSURE
reabsorption - Correct Answers -process whereby renal tubules return materials
necessary to the body back into the bloodstream
semi selective transporters
reabsoptions takes place in - Correct Answers -Proximal CT, loop of henle, distal CT,
and CD
secretion - Correct Answers -blood to lumen
selective active transport
large filtration volume allows for - Correct Answers -speed
renal corpuscle - Correct Answers -glomerulus and bowman's capsule

afferent arteriole - blood in
efferent arteriole - blood out
Bowmans capsule - Correct Answers -lumen space
connected to PCT
bulk flow - Correct Answers -The movement of a fluid due to a difference in pressure
between two locations.
governed by blood hydrostatic pressure
