Thermoregulation

• What is the primary function of thermoregulation?

  To maintain body temperature
• What role does the hypothalamus play in thermoregulation?

  It processes signals from temperature receptors
• What type of receptors are involved in detecting temperature changes?

  Thermoreceptors
• How does the skin contribute to thermoregulation?

  It contains receptors that detect temperature changes
• What is the epidermis?

  It is the outer layer of skin
• What happens to arterioles when the body is cold?

  They undergo vasoconstriction
• What is the effect of vasoconstriction on blood vessels?

  It reduces blood flow to the skin
• How does shivering help in thermoregulation?

  It generates heat through muscle contractions
• What is the process of sweating?

  Evaporation of sweat cools the body
• What happens to the body when temperature rises above $37^\circ C$?


  Arterioles widen through vasodilation
• What is the result of vasodilation in thermoregulation?

  Increased blood flow to the skin
• How does the body lose heat to the surroundings?

  Through increased blood flow to the skin
