Why does your heart suddenly start pounding when you're scared? 😳❤️

It's not random.

When your brain detects a threat, your sympathetic nervous system can activate the body's fight-or-flight response. Signals travel through the nervous system, adrenaline is released, and your heart begins beating faster and more forcefully to help prepare your body for action.

In this 3D medical animation, Body Spectra takes you inside the brain, nervous system, adrenal glands, bloodstream, and heart to visualize what happens during a sudden fear response.
