Hydrostatic pressure is the primary driving force of plasma through the
filtration membrane into the capsular space. All but one of the following
statements reflects why hydrostatic pressure is so high in the glomerular
capillaries. Select the one statement that does NOT explain the high pressure
within the glomerular capillaries.
(a) The volume of plasma in the efferent arteriole is higher when compared to
the afferent arteriole
(b) The flow of blood is reduced as blood reaches the efferent arteriole
(c) The diameter of the efferent arteriole is smaller than the afferent arteriole
(d) The efferent arteriole has higher resistance to blood flow than the afferent
arteriole - ----ANS:a

be secreted by granular cells. Which of the following is NOT likely to occur?
(a) Blood plasma and extracellular fluids volume will increase
(b) Kidney perfusion will increase
(c) Net filtration pressure (NFP) will decrease

(vasoconstriction), which of the following is NOT likely to occur?
(a) Urine output will decrease
, (b) Net filtration pressure will decrease
