- The Kidneys
- Acts as filters to clean the blood
- Removal of urea from blood
- Produced as waste product of liver
- Urea is poisonous - released into blood stream by liver
- Kidneys filter it out of blood
- Temporarily stored in bladder in urine and excreted out
- Adjustment of ion content in blood
- ions e.g, Na taken into body in food then absorbed into blood
- If ion content wrong-upset balance between ions and water meaning too much/little water drawn into cells by osmosis
- Excess ions removed by kidneys
- Some ions lost in sweat
- Adjustment of water content of blood
- Water lost throughurine, sweat, air breathe out
- Water balance between liquids consumed, amount sweated out, amount excreted by kidneys in urine
- Cool day - more urine: pale/dilute, no sweat
- Hot day: less urine dark coloured/concentrated, sweat
