You are cold, VERY cold! Your body responds by:
~Shivering - Muscles contract and relax repeatedly, generating heat by friction and from metabolic reactions.
~Glands secrete adrenaline and thyroxine, which increases the metabolic rate in different tissues.
~Muscles contract, raising skin hairs and trapping an insulating layer of still, warm air next to the skin.
Review the prompt to draw conclusions regarding the primary body systems that cooperate to maintain your internal body temperature.

Explanation:
- The nervous system is involved because the hypothalamus in the brain acts as the control center for temperature regulation, initiating the responses to cold.
- The muscular system participates in shivering to generate heat.
- The integumentary system (skin and associated structures) is involved when muscles contract to raise skin hairs, trapping insulating air.
- The endocrine system is engaged when glands secrete hormones like adrenaline and thyroxine, which help increase the body's metabolic rate to produce heat.
