Final answer:
The false statement is that an increase in glomerular blood hydrostatic pressure results in a decrease in net filtration pressure. In fact, increased glomerular blood hydrostatic pressure enhances glomerular filtration by increasing the net filtration pressure.
Step-by-step explanation:
The false statement is: An increase in glomerular blood hydrostatic pressure causes a decrease in net filtration pressure.
Glomerular filtration is largely driven by the glomerular hydrostatic pressure which forces fluid and solutes through a semipermeable membrane within the kidneys. This filtration process is opposed by both the hydrostatic pressure in Bowman's capsule and the colloid osmotic pressure of the blood due to proteins that cannot pass through. When glomerular blood hydrostatic pressure increases, it generally increases the net filtration pressure as more fluid is pushed into the Bowman's space, enhancing urine formation.
The statements that glomerular capillaries have a higher blood pressure than other capillaries, that blood in the glomerular capillaries flows into arterioles, that vasa recta pass blood from the efferent arteriole toward venules, and that glomerular filtration is promoted by glomerular blood hydrostatic pressure and opposed by capsular hydrostatic pressure and blood colloid osmotic pressure are all true.
