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.
