Is the renal medulla lighter in color?

Postby johntdlemon » Sun Nov 25, 2012 3:33 am

I read on my textbook and here that: http://www.courseweb.uottawa.ca/medicine-histology/english/Renal/Default.htm
The outer part, called the cortex, is a dark reddish brown color. The inner part, called the medulla, is lighter-colored.


But then there are websites that says: http://www.wisegeek.org/what-is-the-renal-cortex.htm
...the medulla is darker in color...the cortex can be identified by its paler color...


I think the cortex should be darker in color since the majority of the capillaries is in the cortex(or is it?), but I can't be sure... :?

Please help! Thanks! :)
