Adrenaline is often referred to as the “emergency hormone” because it is released in response to stress or danger. It prepares the body for a “fight-or-flight” response by:
- Increasing heart rate ❤️: This increases blood flow to the muscles and brain.
- Dilating blood vessels: This lowers blood pressure and increases blood flow to the muscles.
- Increasing blood sugar levels: This provides energy for the muscles.
- Increasing breathing rate: This increases oxygen intake.
✅ Adrenaline is produced by the adrenal glands, which are located on top of the kidneys. It is released into the bloodstream in response to signals from the nervous system
