BT_PO 1.76 Regulation of osmolarity

I visited Canberra towards the end of last year to watch one of my children run. In my (large) amount of free time, I visited the National Portrait Gallery, where I happened upon this portrait of Derek Denton, the Australian scientist who discovered the mechanism of thirst.
