Year 6. Unit 3: Sensitivity II. The nervous system

How do people react in dangerous situations?

• When you are in danger or you are scared, your body reacts with a ‘fight-or-flight’ response. This type of response is automatic, and it gets your body ready for quick action or escape.
• During a ‘fight-or-flight’ response, your heart rate increases, so your heart pumps blood with nutrients and oxygen to your muscles at a faster rate than normal.
• Your breathing becomes quicker to supply more oxygen to your body. The pupils in your eyes dilate so you can see more clearly. Your digestion slows down to save energy. Now you are ready to face the situation!

• Are fight-or-flight responses voluntary or involuntary? 
• They are involuntary, automatic.
• What happens to your breathing during a fight-or-flight response? 
• Your breathing becomes quicker to supply more oxygen to your body.
• Is your digestion affected? Why? 
• Yes, it slows down to save energy. 

•
