homeostasis

• What is homeostasis?

  Maintaining a stable internal environment
• Why is homeostasis important for cells?

  Cells need stable conditions for proper function
• What does homeostasis regulate in the body?

  Conditions inside the body and cells
• What are the two types of communication systems involved in homeostasis?

  Nervous and hormonal communication systems
• What are some examples of control systems in the body?

  Blood temperature, glucose level, water balance
• What are the three main components of automatic control systems?

  Receptors, coordination centres, effectors
• How does negative feedback work in homeostasis?

  It counteracts changes to restore normal levels
• What happens when a level is too high in the body?

  Receptor detects stimulus, coordination centre responds
• What occurs when a level is too low in the body?

  Coordination centre organizes a response to increase level
• What happens if effectors are continuously stimulated?

  They may cause the level to change too much
• How does the receptor contribute to negative feedback?

  It detects if the level becomes too different
• Is the process of homeostasis conscious or automatic?

  It is automatic
