In this post, we have discussed the difference between Excretion and Osmoregulation.
The difference between Excretion has been given in the table below.
| Excretion | Osmoregulation |
| Function. It removes byproducts of metabolism called waste products, | It maintains osmotic pressure of body fluids. |
| Protection. It protects the body from toxicity of waste products. | It protects the body from adverse conditions present in external environment. |
| Elimination. It always involves elimination of waste products. | Elimination of water and salts depends upon the internal conditions. There is elimination in case of excess water and salts. The same are retained in case of deficiency. |
