Answer:
The Glomerular filtration rate (GFR) should increase because of a large increase in the Glomerular capillary hydrostatic pressure (PGC). However, the effect of PGC will be cancelled because of simultaneous dilation of afferent arterioles and constriction of efferent arterioles.
Explanation:
The dilation of the afferent arteriole will decrease the filtration fraction which inturn will increase the diameter of glomerular capillaries. Therefore, the Glomerular capillary hydrostatic pressure (PGC) will increase. However, the constriction of efferent arterioles at the same time decreases the GFR and increases the PGC. Therefore, the person's GFR will remain constant and the filtration fraction will remain unchanged thus the effect of increased PGC will be cancelled.
Answer:
The GFR of this person will increase.
Explanation:
The glomerular filtration rate (GFR) will increase since the resistance in the afferent arteriole has decreased because of the arteriole dilatation. In other words, more blood will be filtrated through the glomerulus due to its bigger radius that allows an increase in the blood's flow.
