homeostasis

Cards (34)

  • What is homeostasis?
    Maintaining a stable internal environment
  • Why is it important to maintain stable conditions inside the body?
    Cells need the right conditions to function
  • What must be regulated for enzyme action in homeostasis?
    The right conditions for enzyme action
  • What does homeostasis regulate?
    Conditions inside your body
  • How does the body respond to changes in internal and external conditions?
    By maintaining stable internal conditions
  • What systems in the body help regulate homeostasis?
    Automatic control systems
  • What do automatic control systems regulate in the body?
    Internal environmental stability
  • What do control systems maintain in the body?
    Body temperature, blood glucose level & water content
  • What is the role of negative feedback in homeostasis?
    To counteract changes and restore normalcy
  • How does the body respond when water levels are too high?
    By using negative feedback to lower levels
  • What detects stimuli in the body?
    Receptors
  • What do receptors do in the context of homeostasis?
    Detect stimuli and send signals
  • How do receptors and effectors work together in homeostasis?
    Receptors detect changes, effectors respond
  • What are the three main components of automatic control systems?
    Receptors, coordination centers, effectors
  • What is the function of coordination centers in homeostasis?
    Process information and coordinate responses
  • What happens when the level of a substance gets too high?
    Negative feedback brings it back to normal
  • How does the body maintain temperature homeostasis?
    By regulating heat production and loss
  • What is the relationship between homeostasis and health?
    Homeostasis is crucial for overall health
  • What is the mechanism called that uses negative feedback in stable environments?
    Negative feedback
  • What happens when the level of something gets too high or too low?
    Negative feedback brings it back to normal
  • What are the steps involved in negative feedback mechanisms?
    1. Stimulus detected by receptors
    2. Coordination center processes information
    3. Effectors produce responses
    4. Responses counteract changes to restore normal levels
  • What do receptors detect in a negative feedback mechanism?
    Stimulus levels
  • What role does the coordination center play in negative feedback?
    Processes information received from receptors
  • What do effectors do in a negative feedback mechanism?
    Produce responses to counteract changes
  • How do effectors respond to changes in levels?
    By counteracting the changes to restore balance
  • What might happen if the level change is too much in a negative feedback system?
    It could lead to the opposite problem
  • What does a receptor detect if the level becomes too high?
    Stimulus level is too high
  • What happens if the level becomes too low in a negative feedback system?
    Receptors detect low levels and respond
  • What is the outcome if the receptors detect a difference in levels?
    Negative feedback starts again
  • How does negative feedback maintain homeostasis in the body?
    By regulating internal conditions through responses
  • What is the significance of negative feedback in biological systems?
    • Maintains homeostasis
    • Regulates internal environment
    • Prevents extreme fluctuations
    • Ensures stability in physiological processes
  • What is the final outcome of a successful negative feedback mechanism?
    Restoration of normal levels
  • What might cause the receptors to detect a change in levels?
    Environmental changes or internal imbalances
  • What could be a consequence of ineffective negative feedback?
    It could lead to health problems
