Answer:
The process is known as secretion
Step-by-step explanation:
When we talk about how Contents in the peritubular capillaries are actively transported into proximal and distal convoluted tubules in a process known as secretion, then we need to mention the kidney as the chief organ that made this possible. Secretion which has waste substance such as hydgoen ions, excess water removed from the blood is part of the process involved in the excretion of urine. Peritubular capillaries are important in the reabsorption and secretion process of urine formation and removal to the bladder. From the question, when they drain their contents into proximal and distal convoluted tubules then the process is called secretion.
