Advanced Physiology Final Exam
Afferent arteriole, glomerulus, efferent arteriole, peritubular capillaries - Answer-Renal blood flow goes
from _____________ to ________________ to ______________ to _______________.
Vasa recta - Answer-The ____________ capillaries dip into the medulla
Bowman's capsule - Answer-Fluid filters from the glomerulus into the __________________-
Proximal tubule, loop of henle, distal tubule, collecting duct - Answer-From the Bowman's capsule, fluid
filters though the __________________, ________________, ______________, and _____________.
Filtration - Answer-The movement of fluid from plasma into Bowman's capsule
Reabsorption - Answer-The movement of filtered materials from tubule to blood
Secretion - Answer-The movement of selected molecules from blood to tubule
Filtration fraction - Answer-1/5 of renal plasma flow filters into the tubule lumen. The percentage of
total plasma volume that filters is called the ____________________
Podocytes - Answer-Bowman's capsule epithelium has specialized cells called ______________ that
wrap around the glomerular capillaries and create filtration slits
, Mesangial cells - Answer-_________________ are associated with the glomerular capillaries. Between
the capillaries contract to alter blood flow
Basal lamina - Answer-Filtered solutes must pass first through glomerular capillary endothelium, then
through a ______________-, and finally through Bowman's capsule epithelium before reaching the
lumen of Bowman's capsule
Plasma proteins - Answer-Filtration allows most components of plasma to enter the tubule but excludes
blood cells and most ____________________
Glomerular filtration rate - Answer-Amount of fluid that filters into Bowman's capsule per unit time.
Average is 180 L/day
Hydrostatic pressure - Answer-__________________ in glomerular capillaries can be altered by
changing resistance in the afferent and efferent arterioles
Myogenic response - Answer-Autoregulation of glomerular filtration is accomplished by a
____________________ of vascular smooth muscle in response to pressure changes and by
tubuloglomerular feedback
Macula densa - Answer-When fluid flow through the distal tubule increases, the
_________________________ cells send a paracrine signal to the afferent arteriole, which constricts
Systemic signals - Answer-Reflex control of GFR is mediated through _____________________, such as
hormones, and through the autonomic nervous system
Proximal tubule - Answer-Most reabsorption takes place in the _______________
Finely regulated absorption - Answer-_______________________ takes place in the more distal
segments of the nephron
