How food moves in the opposite direction during vomitting Related:  Digestion in Human Beings?

Answer

How food moves in the opposite direction during vomiting

Reverse Peristalsis: When we eat food, it travels down the esophagus to the stomach through a series of muscle contractions known as peristalsis. During vomiting, the muscles in the digestive tract contract in the opposite direction, pushing the food back up towards the mouth.
Opening of the Lower Esophageal Sphincter: The lower esophageal sphincter is a ring of muscle at the bottom of the esophagus that normally prevents food from flowing back up. During vomiting, this sphincter relaxes, allowing food to move in the opposite direction.
Forceful Contractions: The muscles in the stomach and diaphragm contract forcefully during vomiting, creating pressure that pushes the food upwards.

Digestion in Human Beings

Ingestion: The process begins with the ingestion of food through the mouth.
Mouth: Food is chewed and mixed with saliva, which contains enzymes that start breaking down carbohydrates.
Esophagus: The food is then swallowed and moves down the esophagus to the stomach through peristalsis.
Stomach: In the stomach, food mixes with gastric juices that contain enzymes and hydrochloric acid to break down proteins.
Small Intestine: The partially digested food moves to the small intestine, where enzymes from the pancreas and bile from the liver further break down nutrients.
Absorption: The nutrients are absorbed through the walls of the small intestine into the bloodstream.
Large Intestine: Any undigested food moves to the large intestine, where water is absorbed, and waste is formed into feces.
Elimination: Feces are eliminated through the rectum and anus as waste.

Answer

When the peristaltic movement is reversed by any reason, instead of food going inside our mouth it comes out as vomiting.
