Answer:
Explanation:
1. This heating system maintains room temperature at or near a particular value, known as the set point.
A temperature setpoint is the level at which the body attempts to maintain its temperature. When the setpoint is raised, the result is a fever.
2. You open the window, and a blast of icy air enters the room. The temperature drops to 17 degrees Celsius, which acts as a STIMULUS to the heating system.
3. The thermostat is a SENSOR that detects the stimulus and triggers a response.
Thermostat is use to turn off or on a switch, when the temperature is high or low
4. The heater turns on, and the temperature in the room INCREASE until it returns to the original setting.
This is the work of the thermostat above, when the temperature of the room is below a certain temperature the thermostat triggered the switch and keep increasing the temperature of the room until normal setting.
5. The response of the heating system reduces the stimulus. This is an example of NEGATIVE feedback.
Body temperature is regulated by negative feedback. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body.
6. The way this heating system maintains a stable room temperature is similar to the way an animal's body controls many aspects of its internal environment. The maintenance of a relatively constant internal environment is known as HOMEOSTASIS.
Humans rely on homeostasis to keep their core temperature hovering around 98.6 degrees Fahrenheit, so that their bodies can maintain proper function. Homeostasis is the ability to maintain a relatively stable internal state that persists despite changes in the world outside.
