The filtrate flows from the Bowman’s capsule into the renal tubule called the proximal convoluted tubule then into the loop of Henle‚ and finally into the distal convoluted tubule: a. Proximal Convoluted Tubule b. Loop of Henle c. Distal Convoluted Tubule 4. When the radius of the afferent arteriole was decreased‚ the pressure and the filtration rate both decreased. 5.
