Study Notes
Human Systems and Homeostasis
- Human systems work together to maintain optimal cellular function.
- Composition of extracellular fluid (ECF) remains consistent throughout the body due to constant mixing of interstitial fluid and blood.
- Blood circulation contributes to the uniformity of ECF composition.
Components of Homeostatic Systems
- Sensor: Detects changes in environmental variables or stimuli, such as temperature fluctuations.
- Control Center: Receives and interprets messages from the sensor; located in the nervous system, specifically the brain or spinal cord.
- Effector: Initiates changes based on the control center's commands to restore balance.
Positive Feedback Mechanisms
- Positive feedback does not always result in instability; it can have necessary roles in certain physiological processes.
