Question

Which arteriole radius adjustment was more effective at compensating for the effect of low blood pressure on the glomerular filtration rate? explain why you think this difference occurs?

Answer 1

Answer
Increasing the afferent arteriole radius.

Step-by-step explanation;
Increasing the afferent arteriole radius or decreasing the efferent arteriole would compensate for the effect of reduced blood on the glomerular rate. However, Increasing the afferent radius had a greater effect than decreasing the efferent radius because there was a greater increase in glomerular pressure.
