INDEX of notes on homeostasis - kidneys and osmoregulation water content control - ion and glucose concentrations - kidney function - associated liver function - kidney failure - dialysis Doc Brown's biology exam revision study notes See also homeostasis - blood sugar control - diabetes homeostasis - thermoregulation - temperature control Sub-index for section on kidney function and osmoregulation (parts overlap each other) (1) What is osmoregulation and why is it needed? (2) Three functions of the kidneys (plus mention of associated liver function) (3) Some details on how the kidney works in conjunction with the urinary and blood systems (4) More on controlling water balance/content - input/output sources - sweating/dehydration (7) Dialysis - an artificial means of purifying the blood (8) Kidney transplants and problems - transplant or dialysis? 'Pros and Cons' Practical work to help develop your skills and understanding may have included the following:
