Osmoregulation
Paul Andersen explains how organisms regulate their internal osmolarity or not. He starts with a brief description of osmosis and why it is important for animal cells to be surrounded by an isotonic solution. He then explains how freshwater and saltwater fish osmoregulate. He finally discusses the nephron within the kidney as an osmoregulatory organ.
