The document discusses how the human body adapts to cold temperatures through its circulatory, cardiovascular, muscular, skeletal, and integumentary systems. The circulatory system reduces blood flow to the extremities and sends more blood to the core to prevent hypothermia. The cardiovascular system pumps blood slower. The muscular system causes shivering to produce heat. People also group together and add extra layers of clothing to retain body heat and use space heaters, blankets, and pillows to block heat loss.

2. Circulatory System Blood is pumped to the body’s core to prevent hypothermia Blood vessels shrink by reducing blood flow from the core to the periphery to keep the body warm

3. Cardiovascular System Blood pumps slower Blood is pumped to the body’s core to eliminate hypothermia

4. Muscular System The body shivers which produces heat to keep warm Muscles contract to contain energy

5. Skeletal and Integumentary Systems Humans group together and get their bodies close to retain heat People add more layers of clothes to keep heat in their body

6. Special equipment to stay warm Layers of clothes Space heater (if possible) Pillows and blankets to block heat from leaving through doors and windows. Alcohol warms the body
