The circulatory system constricts blood vessels near the skin to reduce heat loss and redirects blood to vital organs. The endocrine system may release hormones like thyroxine to increase metabolic rate and produce more heat.

Answer:

The nervous system detects cold and signals the muscular system to shiver for heat production. The circulatory system constricts blood vessels near the skin to minimize heat loss and redirects blood to vital organs. The endocrine system may secrete hormones to boost metabolic rate and generate more heat.
