- The kidney's & Homeostatis
- The job of the kidney's
- Removal of urea
- Protein's can't be stored in the body
- So they're converted to carbohydrates and fats
- This process occurs in the liver
- The waste product of this reaction is urea
- So they're converted to carbohydrates and fats
- Urea is poisonous
- Urea is released into the bloodstream by the liver
- Kidney's then filter it out of the blood
- Urea is released into the bloodstream by the liver
- temporarily stored in in the bladder and urine is excreted from the body
- Protein's can't be stored in the body
- Adjustment of Ion content
- ion is taken into the blood through food
- If there is too much ion compared to water (or vice versa) the balance is wrong
- This effects the effectiveness of osmosis
- Damages cells
- Stops them working
- Damages cells
- This effects the effectiveness of osmosis
- Excess ions are removed by the kidney's
- e.g sodium/salt
- Some ions are lost in sweat
- Adjustment of water content
- Water is taken into the body as food and drink
- It's then lost by: Urine, Sweat and in the air we breathe out
- The body has to balance the amount of water we take in to the amount we get rid of.
- The balance is between: Liquids consumed- Amount sweated out- amount lost as urine
- On a cold day
- You dont sweat
- You'll produce more urine
- Pale and dilute
- On a warm day
- You'll sweat lots
- Produce less urine
- Dark in colour and concentrated
- Water is taken into the body as food and drink
- Removal of urea
- Sports Drinks
- filled with water, sugar and ions
- replace minerals lost in sweat during sport
- Replaces sugar used up by muscles during excercise
- Not all are scientifically proven
- filled with water, sugar and ions
- The job of the kidney's
