FEEDBACK MECHANISM

Feedback Mechanism

Processes that regulate physiological activities to maintain homeostasis.

Negative Feedback

Mechanism where the response inhibits the initial stimulus to maintain stability.

Positive Feedback

Mechanism where the response amplifies the initial stimulus.

Homeostasis

The ability to maintain a stable internal environment despite external changes.

Body Temperature Regulation

Processes like sweating, vasodilation, vasoconstriction, and shivering to maintain optimal body temperature.

Glucose Level Regulation

Control of blood glucose levels through insulin and glucagon release by the pancreas.

Tissue Fluid and Blood

Blood system maintaining stable tissue fluid composition for cellular function.

Pancreas

Organ containing cells that produce insulin and glucagon for glucose regulation.

Hypothalamus

Brain region with sensors monitoring body temperature for temperature regulation.

Gastrointestinal Tract

Controls glucose absorption rate and stimulates insulin secretion for glucose homeostasis.
