Summary Introduction

To describe: Osmoregulatory organs in invertebrates.

Introduction: Osmosis refers to the process of diffusion of water molecules across a semipermeable membrane. This movement of water molecules typically occurs to a less dilute solute from a more dilute solute. The osmotic pressure denotes the measure of the solution’s tendency to gain water molecules through osmosis. Based on the osmotic regulation, organisms are broadly classified into two types, namely osmoconformers and osmoregulators. Osmoregulators maintain a comparatively stable blood osmolarity despite the occurrence of different concentrations in their environment.
