Homeostasis
Control of the Body temperature through Homeostasis
| Question | Answer |
|---|---|
| What is Homeostasis | The process if keeping a system in a constant state. Such as the process of keeping body temperature through a series of negative feedback processes. |
| Negative Feedback: | A change in a variable effects a change in the system to reduce the original change. |
| What are the receptors in the skin and the brain that are sensitive to heat called? | Thermoreceptors. |
| What is the core body temperature? | 37 Degrees C |
| What is the section of the brain called that regulates temperature? | The Hypothalamus |
| What changes in the body does the Hypothalamus effect to lower body temperature? | The Erector Pili muscles of hair relax causing hair to lie flat, any shivering stops, metabolic rate may lower to prevent heat production, sweating occurs from sweat glands on the skin, Vasodilation occurs to allow blood to flow closer to skin. |
| What changes in the body does the Hypothalamus effect to increase body temperature? | Shivering by rapid muscle contraction occurs, sweating stops, erector phili muscles contract causing hairs to stand up and trap more air, metabolic rate can increase to produce heat, Vasoconstriction to make blood flow more in the core away from skin. |
| Why are negative feedback responses important in a system such as the human body: | They help to keep conditions constant within a specific range. |
