IB Biology Topic 11.3 (HL): The kidney & osmoregulation - Part 2

This video delves into the detailed processes of osmoregulation by the kidneys. It moves in a sequential order from solute absorption in the proximal convoluted tubule to water absorption in the loop of Henlé and fine-tuning of both by the distal convoluted tubule and collecting duct, respectively. It then moves on to discuss dehydration and over hydration, and ends on by covering the diagnosis and treatment of kidney failure.
