Hey guys,

 

I'm currently in a Physiology class and we were asked to critically think about why our body has a convoluted system for creating urine. The fluid goes through multiple stages to concentrate and unconcentrate before it becomes urine. Why is it that our body doesn't have a direct system from A to B? Does it have to do something with the ions or energy conservation?

 

Appreciate your help.

Thanks

I'd go the comparative physiology route. I have a book here somewhere on it but googling should work. I know that for mammals we have an ever changing environment and there is what would appear to be quite a dicey method to keep all minerals, sugar,water etc. in balance. But it would be interesting if other animals can stand greater variations and so don't need such sophistication.

The reason is pretty straightforward. Energy conservation is usually meant in a very specific context, and is mostly used in a cellular context (i.e. ATP conservation).

 

The easiest way is to list the different stages and the processes during each stage and what the consequences are if you bypass them. Ions do play a role, for instance.

A direct path would nnot favor some of the processes involved. take for example the vasa recta and the counter current mechanism, a direct system wouldn't be able to provide such functions
