Human anatomy

Can any one help me with this question?

Describe the process of osmoregulation and its importance in maintaing cellular activity

[MORELLO]

This is physiology, not anatomy? Osmoregulation is simply the movement of water across a semi-permeable membrane in & out of the cell as needed to allow the components of that cell to work/behave effectively.

what level of study are you at hannah?

Sorry to be picky Morello, but that's osmosis.  Osmoregulation is the control of the amount of water in the body, by hormones such as anti-diuretic hormone (ADH) that stops you peeing much when you're short of water.  When you have more water than you need, ADH secretion stops and your kidneys will get rid of water until the blood levels indicate that water needs to be conserved, when ADH is released again.  Negative feedback loop.
