Answer 1

Two Responses that Prepare the Human Body to Deal with a Scary Situation:

During a frightening or emergency situation, the adrenal glands release the hormone adrenaline. This hormone prepares the body for quick action (fight or flight response).

1. Increase in Heartbeat and Blood Pressure:
– The heart beats faster.
– Blood pressure increases.
– More blood is supplied to muscles and brain.
– This provides extra oxygen and energy for immediate action.

2. Increase in Breathing Rate:
– Breathing becomes faster and deeper.
– More oxygen enters the lungs.
– Oxygen supply to body cells increases.
– This helps muscles work efficiently during emergency.

Conclusion:
An increase in heartbeat and breathing rate are two important responses that make the human body ready to deal with a scary or emergency situation.
