Which of the following is NOT an example of a reflex action? A. quickly withdrawing your hand after touching a hot pan B. passing food through your digestive tract C. blinking your eye when a splinter gets into it

"B. passing food through your digestive tract.

The movement of food through the digestive tract is caused not by a reflex but by peristalsis. Peristalsis is the process by which a series of radially symmetrical contractions and relaxations occur anteriorly along the digestive tract, called peristaltic waves."
