Homeostasis <ul><li>According to Dictionary.com homeostasis is defined as: a state of psychological equilibrium obtained when tension or a drive has been reduced or eliminated </li></ul><ul><li>In order to maintain homeostasis in the deep oceans you need to adapt to the water temperature by dressing properly. </li></ul>
  3. 3. Extreme Conditions/Adaptations <ul><li>*Water temperature: </li></ul><ul><li>Hypothermia: 98.6°F to 89.6°F, the body begins to shiver, blood vessels contract, and hormones generate heat. </li></ul><ul><li>In cold water, core temperature can drop to dangerous levels in a matter of minutes. </li></ul><ul><li>*Water Pressure- </li></ul><ul><li>The deeper you go into the deep oceans the water pressure begins to increase. It can become uncomfortable swimming deep down into the oceans because of the great pressure. </li></ul>

  7. 7. Circulatory System <ul><li>High water pressure causes the capillaries especially at the legs, to contract. </li></ul><ul><li>This results in over cooling of the limbs. </li></ul>
