Q: Like a house, your body has what kind of mechanism that responds to changes in temperature? Read this paragraph and choose the correct option from the provided answers: For example, your body has an internal thermostat. During a winter day, in your house a thermostat senses the temperature in a room and responds by turning on or off the heater. Your body acts in much the same way. When body temperature rises, receptors in the skin and the brain sense the temperature change. The temperature change triggers a command from the brain. This command can cause several responses. If you are too hot, the skin makes sweat and blood vessels near the skin surface dilate. This response helps decrease body temperature. Choices: - external thermostat - mechanical thermostat - sensitive thermostat - internal thermostat A:
**Answer**
internal thermostat
