Question

Tina's heart began to beat much faster when it came to the scary scene in the movie. Which portion of the nervous system causes the heart to beat faster when afraid

Answer 1

Sympathetic

Step-by-step explanation:

Your autonomic system then leads into sympathetic or parasympathetic. Parasympathetic relaxes you while sympathetic causes the "fight or flight" response to perceived dangers, which is what is making Tina's heart rate go up while watching the scary part of the movie.
