Homeostasis_and_Control.csv

What is homeostasis?

Maintenance of a stable internal environment

What is a control system?

A system that monitors and adjusts physiological variables

What are the components of a control system? (R, CC, E)

Receptor, control center, effector

What does a receptor do?

Detects changes in the environment

What does the control center do?

Processes information determines response and issues commands

What does an effector do?

Produces a response to restore balance

What is negative feedback?

Response that reverses a deviation from the set point

What is positive feedback?

Response that amplifies a change

Example of negative feedback?

Body temperature regulation

Example of positive feedback?

Blood clotting or childbirth contractions

What is a set point?

Desired value maintained by homeostasis

What is thermoregulation?

Maintaining body temperature within normal range

What role does the hypothalamus play in homeostasis?

Integrates neural and endocrine control of body systems

What is fluid balance regulation?

Control of water and electrolyte levels

What hormones regulate fluid balance?

ADH aldosterone and ANP

What is blood glucose regulation?

Maintaining glucose within normal limits through insulin and glucagon

What is osmoregulation?

Regulating solute concentration and water balance

What is the role of effectors in homeostasis?

Carry out responses that restore equilibrium

What happens if homeostasis fails?

Illness dysfunction or death

What is feedforward control?

Anticipation of changes before they occur
