  • Homeostasis
    • Homeostasis= maintaining a steady state of the internal body (i.e. 37°C) when external environment changes
    • Examples of Normal Values (for human internal environment)
      • pH of blood: 7.4 (± 0.1)
      • Blood sugar: 0.1%
      • Body temperature: 37°c (± 1°c)
    • Negative Feedback Control
      • Thermoregulation of body
        • High temperature in body
        • Low temperature of body
    • 2 types of Animals
      • Terrestrial Animals- animals that live on land
        • Gain water from food & drink
        • Lose water via urinating, defecating & evaporation
      • Aquatic Animals- animals that live in water
        • Osmoconformer
