Questions and Answers

What is the role of the hypothalamus in thermoregulation?

  • It controls the production of red blood cells
  • It regulates blood pressure
  • It acts as the thermostat for the body temperature (correct)
  • It secretes digestive enzymes

    • What happens beyond a body temperature of 42°C?

  • The body enters a state of hibernation
  • The body becomes more resistant to infections
  • Cytotoxicity occurs with protein denaturation and impaired DNA synthesis (correct)
  • The immune system becomes more effective

    • What are the potential consequences of severe hypothermia?

  • Improved cognitive function
  • Neuromuscular, cardiovascular, hematological, and respiratory changes with fatal outcomes (correct)
