Study Notes
Homeostasis and Negative Feedback
- Homeostasis refers to the body's ability to maintain a constant internal environment.
Components of Negative Feedback
- The receptor senses changes in the internal environment and sends information to the control center.
- The control center analyzes information and determines an appropriate response.
- The effector carries out the response to restore balance.
Role of Negative Feedback
- The primary purpose of negative feedback is to maintain homeostasis.
- Negative feedback helps to counteract changes in the internal environment.
- When an imbalance is sensed, the receptor sends information to the control center, which analyzes the data and sends a signal to the effector to restore balance.
Physiological Needs for Homeostasis
- Basic physiological needs necessary to maintain homeostasis include water, oxygen, nutrients, and waste removal.
- Sleep is NOT a basic physiological need necessary to maintain homeostasis.
Control Center
- The control center is responsible for analyzing information and determining an appropriate response.
Effector
- The effector carries out the response to restore balance in the internal environment.
Test your knowledge on homeostasis and its importance in maintaining a stable internal environment. Learn about the physiological needs and regulation involved, as well as the role of negative feedback mechanisms.
