Study Notes
Homeostasis
- The body maintains a stable internal environment.
- Homeostasis is the process of keeping the internal environment within a narrow range.
Homeostasis Components
- Sensors collect data about the internal environment
- Control centers receive the data from sensors and send messages to targets.
- Targets respond to the messages from the control center to change the internal environment.
- Communication systems deliver the messages from the control center to targets.
- Examples of targets include: sweat glands, hair follicles, and muscles.
Feedback Loops
- Negative feedback loops stop changes in the internal environment.
- Negative feedback compares the current state of the internal environment to the set range.
- Mechanisms that increase heat production: increased sensation of hunger and appetite, and increased catecholamine and thyroxine.
- Excess sweating can lead to dehydration and loss of electrolytes, which can cause miner's cramps, especially in hot and humid conditions.
