Question

glomerular filtration rate (gfr) will increase when: question 1 options: a. the colloid osmotic pressure of plasma decreases. b. the hydrostatic pressure in bowman's capsule increases. c. the afferent arteriole vasoconstricts. d. (a) and (b) are correct; (c) is incorrect e. (a), (b), and (c) are all correct

Answer 1

The glomerular filtration rate (GFR) is influenced by several factors, including a) colloid osmotic pressure.

Step-by-step explanation:

GFR will increase when conditions favor filtration over reabsorption. In this case, a decrease in the colloid osmotic pressure of plasma (option A) would mean that there is less opposing pressure to fluid leaving the capillaries, thereby increasing GFR. Conversely, an increase in the hydrostatic pressure in Bowman's capsule (option B) would oppose filtration and thus decrease GFR.

Additionally, constriction of the afferent arteriole (option C) would reduce blood flow into the glomerulus and consequently decrease GFR. Therefore, the correct answer to the question is that GFR will increase when 'the colloid osmotic pressure of plasma decreases.' This means the correct answer is option A.

The correct answer is option A, where a decrease in colloid osmotic pressure of plasma will result in an increased GFR, because there is less opposing pressure to fluid leaving the capillaries.
