level: homeostasis
Questions and Answers List
level questions: homeostasis
| Question | Answer |
|---|---|
| Describes all the mechanisms by which a constant internal environment is maintained | homeostasis |
| True or False: The external environment affects homeostasis? | False |
| Tissue fluids must: | 1. be within a small range of pH (acidity) 2. contain enough glucose for respiration and activity 3. contain enough oxygen for respiration 4. be specific for body cells to function normally 5. be within small temperature range 6. not contain high levels of carbon dioxide and nitrogenous waste |
| Examples of homeostasis | excretion and osmoregulation |
| Waste products that can damage and kill cells: | Carbon Dioxide, Nitrogenous Waste, low temperature, high temperature, too much water |
| Effect of Carbon dioxide build up | pH of blood and tissue fluid lowers which affects the rate at which chemical reaction occur within the cell |
| Effect of nitrogenous waste build up | toxic to cells |
| Effect of Low temperature | chemical reaction are too slow |
| Effect of high temperature | denatures proteins and enzymes |
| Effect of too much water | body cells malfunction |
| Why is homeostasis important? | because cells need a constant environment to function efficiently |
