Urea causing haemolysis

[Stroodle]

Hi,

I'm new to this forum. I'm just starting a biomedicine degree, so I guess I'll be here often - asking questions, and contributing.

I'm running through some textbook questions, and want to know the answer to the following:

Urea is a normal component of our body fluids. Why does it not cause haemolysis in the body?

Is the reason because it's lipid soluble, and hence the osmotic pressure caused by it is the same both in and outside of the cell?

Thanks for your help

Have you thought about concentrations and how they are regulated?

You're in Unimelb doing your lab #2 right? haha I just searched the internet looking for the answer to that too...

because it's lipid soluble

are you sure?
