Answer 2

Answer:

Correct option: B

Explanation:

The movement of food through the gastrointestinal (GI) tract involves various muscles and nerve impulses.

• When the food is swallowed, it enters the GI tract.
• The gastrointestinal tract is like a long, hollow muscular pipe.
• Once, the food enters, these smooth muscles of the tract start contracting behind the food, which causes the food to move further down the digestive tract and reach the stomach.
• This process of involuntary contraction of the muscle is called peristalsis.
