Question

Match the terms to these definitions:

(Excretion, micturition, hemodialysis, ureotelic, uricotelic, transport maximum, glomerular filtration rate, osmoregulation, renal threshold, nephron, countercurrent system, ultrafiltration)

.......... is the control of electrolyte and organic solute concentrations in the body fluids, and maintenance of water balance and fluid volume.

Answer 1

Osmoregulation refers to the control of electrolyte and organic solute concentrations in the body fluids, and maintenance of water balance and fluid volume.

Osmoregulation is usually achieved by excretory organs that serve also for the disposal of metabolic wastes. Thus, urination is a mechanism of both waste excretion and osmoregulation.
