The adrenalin flow rises. Your nerves make your heart beat go faster. Anxiety is also the cause.

This is a defense mechanism in your body to help you get through the situation. Adrenalin is released and this results in the faster heart rate which helps provide more oxygen to your tissue so you can deal with the situation. It is known as the fight of flight response and the extra oxygen prepares you to deal in either way, depending on your circumstances and what you may have to do to keep yourself safe.

---

Your heart starts beating really fast because your body is preparing for an emergency situation. If the situation were to worsen or become more dangerous your body would send the blood to the muscles and organs essential for life. That way your muscles could work harder and help you run from the danger. At the same time your non essential organs would take a break and get lett blood flow. It's just your body's natural way to be prepared to save your life.
