Components of a control system

Cards (37)

  • How does a control system in physiology function?
    It keeps the body's internal environment stable
  • What are the components of a control system in physiology?
    • Receptor: Detects changes in body conditions
    • Control center: Compares information to set points
    • Effector: Responds to restore balance
  • What are the three key parts of a control system?
    Receptor, control center, effector
  • What happens when you get cold in terms of the control system?
    Shivering is triggered to raise temperature
  • What role does the control center play in a control system?
    It processes information and decides how to respond
  • How does a receptor function in a control system?
    It detects variations like temperature or blood pressure
  • What does the receptor communicate with after sensing changes?
    The control center
  • How does the function of effectors contribute to homeostasis?
    Effectors restore balance in the body
  • How does the control center compare current conditions?
    It compares them to the set points
  • What is the primary function of negative feedback mechanisms?
    To keep the body stable
  • What do sweat glands do when the body gets hot?
    They produce sweat to cool you down
  • What happens after the baby is born in positive feedback?
    It stops amplifying contractions
  • What is the relationship between the receptor, control center, and effector in the body?
    • Receptor senses changes in the environment
    • Control center processes this information
    • Effector carries out the response
  • What are the two types of feedback mechanisms in the body?
    Negative and positive feedback
  • What are the key differences between negative and positive feedback mechanisms?
    • Negative Feedback:
    • Purpose: Stabilize body
    • Response: Counteracts change
    • Example: Maintaining temperature

    • Positive Feedback:
    • Purpose: Amplify change
    • Response: Enhances change
    • Example: Blood clotting
  • What is the term for the stable internal environment maintained by a control system?
    Homeostasis
  • Why is a control system compared to a thermostat?
    Both maintain stability in their environments
  • What is a control system in physiology?
    A system that maintains homeostasis
  • How does the control center function in a physiological control system?
    It compares detected changes to set points
  • What does the effector do in a control system?
    It takes action to restore balance
  • What is a receptor?
    A specialized cell or tissue
  • What is the role of the control center in the body?
    Processes information and decides how to respond
  • How does the control center interact with the effector?
    The control center directs the effector to act
  • How does negative feedback work in the body?
    It counteracts changes to maintain stability
  • How does negative feedback function in the body?
    It maintains balance by opposing changes
  • What is the primary function of a receptor?
    To sense changes in the body's environment
  • What is the primary function of positive feedback mechanisms?
    To amplify changes
  • What is the main goal of negative feedback mechanisms?
    To keep conditions just right
  • What happens when your body gets too hot?
    Your body cools you down
  • How does positive feedback work in the body?
    It enhances changes to complete processes quickly
  • How does positive feedback work in the body?
    It amplifies changes until a significant event occurs
  • What analogy is used to describe the function of a receptor?
    Like a thermometer in a thermostat
  • What role does the control center play after receiving information from the receptor?
    It initiates the necessary response
  • What does your body do when it gets too cold?
    Your body warms you up
  • How does a thermostat function as a control system?
    • Thermometer acts as the receptor
    • Thermostat is the control center
    • Heater or air conditioner is the effector
    • Receptor alerts control center to turn on heater when cold
  • What are the key differences between negative and positive feedback mechanisms?
    • Negative Feedback:
    • Opposes changes
    • Maintains balance
    • Examples: temperature regulation
    • Positive Feedback:
    • Amplifies changes
    • Leads to significant events
    • Examples: childbirth
  • What is the function of the receptor in a control system?
    It senses changes in your body
