Question

if the diameter of afferent arteriole is decreased and that of efferent renal arteriole increased and becomes more than that of the afferent arteriole diameter, ultra filtration will be
a)be faster
b)be reversed in direction from capsular space to loop of henle
c)not take place
d)take place at the same speed
​

Answer 1

Answer:

If the diameter of afferent arteriole is decreased and that of efferent renal arteriole increased and becomes more than that of the afferent arteriole diameter, ultra filtration will be

Not takes place.

Explanation:

It is necessary to have less diameter in efferent arteriole,because blood has to be retained some time for ultrafiltration,

Which is done due to less diameter of efferent arteriole than afferent arteriole.
