Fight or Flight Response

• What happens to our hearts during a stressful situation?

  They beat faster
• What is the term for the body's reaction to stress?

  Fight or flight response

  
• What does the fight or flight response prepare the body for?

  Defending/attacking or running away

  
• What changes occur in the body during the fight or flight response?

  Nervous system changes and hormone secretion

  
• Why did the fight or flight response evolve?

  As a survival mechanism

  
• What is the role of the amygdala in the fight or flight response?

  It processes threats and triggers the response

  
• Which hormone is primarily associated with the fight or flight response?

  Adrenaline

  
• What are the potential negative consequences of the fight or flight response?

  Increased blood pressure and heart disease

  
• How does the fight or flight response differ in modern life compared to its evolutionary purpose?

  Modern stressors rarely require physical activity
• What is the fight or flight response?

  The body's reaction to a threatening or stressful situation

  
• What are the physiological changes that occur during the fight or flight response?

  Faster heartbeat, rapid breathing, and tense muscles

  
• What is the purpose of the fight or flight response?

  To prepare the body for defending/attacking or running away

  
• How does the fight or flight response work?

  It involves changes in the nervous system and hormone secretion

  
• What is the evolutionary purpose of the fight or flight response?

  To enable a quick reaction to life-threatening situations

  
• What are the key terms associated with the fight or flight response?

  Amygdala, hypothalamus, sympathetic nervous system, adrenaline, parasympathetic nervous system, adrenal medulla

  
• Why can the fight or flight response be problematic in modern life?

  The stressors of modern life rarely require physical activity
• What are the negative consequences of the repeated activation of the sympathetic nervous system?

  Increased blood pressure can lead to physical damage and heart disease
• What are the key components of the fight or flight response and how do they work together?

  • Amygdala: Detects threat and triggers the response
  • Hypothalamus: Activates the sympathetic nervous system
  • Sympathetic nervous system: Increases heart rate, breathing, and muscle tension
  • Adrenal medulla: Releases adrenaline to sustain the arousal
  • Parasympathetic nervous system: Helps the body return to normal after the threat passes
