1. kidneys..
can produce about 0.5 to 2 liters of urine per day, depending on
what you eat or drink.
maintain an interstitial fluid concentration gradient that is
higher in the renal cortex and lower in the renal medulla.
produce urine of constant composition in order to maintain
homeostasis.
filter 1.8 liters of blood plasma each day.
2. what is proper order in which blood passes through the
blood vessels associated with the nephron
vasa recta, glomerulus, afferent arteriole, efferent arteriole,
peritubular capillaries
efferent arteriole, glomerulus, afferent arteriole, peritubular
capillaries, vasa recta, peritubular capillaries
glomerulus, peritubular capillaries,afferent arteriole, efferent
arteriole, vasa recta, peritubular capillaries
afferent arteriole, glomerulus, efferent arteriole, peritubular
capillaries, vasa recta, peritubular capillaries
3. if the blood pressure fluctuates beyond the limits of
normal homeostatic range, glomerular filtration rate
(GFR)
will increase to compensate for decreases in blood pressure.
will increase to compensate for increases in blood pressure.
will remain constant due to autoregulation.
4, vasoconstriction of the afferent arteriole results in
increased GFR.
decreased GFR.
no change in GFR.
increased urine formation.
