Biology 3 Revision- Keeping internal conditions constant
- For the body to work properly the conditions surrounding your cells must stay constant.
- As you move you produce energy which warms up the body
- As you respire you produce waste
- When you digest food you take millions of molecules into your body
- HOMEOSTASIS- helping to keep the internal environment constant.
- Cells of the body contantly produce waste products, the products of chemical reactions which take place in cells.
- The more extreme conditions, the more waste products the cells make
- Two main poisonous waste products Urea and Carbon Dioxode.
How to remove Carbon Dioxide:
- C02 is produced during respiration (food molecules break down and release energy to cells)
- Every cell respires, so every cell produces Carbon Dioxide
- Dissolved Carbon Dioxide produces an acidic solution which can affect the working enzymes in cells.
- CO2 moves out of cells into the…
