Question

1.How does food move in opposite direction during vomiting?​

Answer 1

Answer:

When we vomit, an anti-peristaltic movement pushes food in the opposite direction to the peristaltic waves that normally move food down through the digestive tract. A reflex closes the glottis to prevent vomit from going into the trachea and the lungs.

Answer 2

Explanation:

The intestine pressure formed in the stomach

when the food is not accepted by the stomach.

The content in the stomach is then pushed back.

This returned content is expelled our from the mouth in the form of vomiting
