Adrenaline Response (рдПрдбреНрд░реЗрдирд╛рд▓рд┐рди рдкреНрд░рддрд┐рдХреНрд░рд┐рдпрд╛): When adrenaline is secreted into the blood, it triggers the ‘fight or flight’ response, which includes increased heart rate, elevated blood pressure, expanded air passages in the lungs, and a surge in energy levels. This prepares the body to deal with immediate threats or stressful situations.
- Increased heart rate and blood pressure:┬аSupplies more oxygen to the muscles
- Faster breathing:┬аDilates air passages to provide more oxygen to the muscles
- Increased blood sugar levels:┬аProvides energy to the body
