Question

Urinary tuble is long, coiled and surrounded by a rich network of capillaries....​

Answer 1

Answer:

The ions that need to be excreted as waste are secreted from the capillaries into the nephron to be sent towards the bladder and out of the body. Essentially, the peritubular capillaries reabsorb useful substances such as glucose and amino acids and secrete certain mineral ions and excess water into the tubule.
