What is the role of the nervous system in digestion?

Question

a. to provide passage of nutrients throughout the body
b. to provide enzymes
c. to provide oxygen
d. to provide electrical signals to initiate peristalsis

Answer 1

The correct answer is: d. to provide electrical signals to initiate peristalsis.

The nervous system plays a crucial role in digestion by coordinating the contractions of the smooth muscles in the gastrointestinal tract through electrical signals, which initiate peristalsis—the wave-like movements that propel food through the digestive system.
