Final answer:

The skin helps regulate body temperature by sweating, increasing blood flow, and through heat receptors.


Explanation:

The skin plays a crucial role in maintaining body temperature through various mechanisms:

  1. One way is through sweating, where sweat evaporates from the skin surface, absorbing heat and cooling the body.
  2. Another is by increasing blood flow to the skin, allowing heat to be released to the environment, aiding in cooling the body.
  3. Furthermore, the skin contains heat receptors that trigger responses like sweating or shivering to regulate body temperature effectively.
