How does our body respond when adrenaline is secreted into the blood?

When adrenaline is secreted, the body prepares for fight or flight.

Adrenaline is released by adrenal glands in stress. It makes the heart beat faster, increases blood pressure, dilates pupils, and supplies more oxygen to muscles. It also increases blood sugar by breaking down glycogen. This makes the body stronger, faster, and more alert for emergencies.

Effects of Adrenaline:

• Faster heartbeat
• Rapid breathing
• Dilated pupils
• More glucose in blood
• Muscles get extra oxygen
