Question

Homeostasis is how your body stays in balance. What happens inside your body when you get too cold? Explain how different cells work to warm you up In 1 or 2 sentences.

Answer 1

When you get too cold, the hypothalamus senses the drop and activates the sympathetic nervous system and motor pathways to raise heat production. Smooth muscle cells in arterioles constrict to reduce heat loss, skeletal muscle cells contract rapidly (shivering) to generate heat, and brown fat adipocytes burn fuel via UCP1-driven thermogenesis for additional warming.
