Describe how the action of the action of the mouth,aesphogus and stomach contribute to the digestion of food
AURORKA [14]

Answer:

Mouth: The process of food breakdown first begins in the mouth. The tooth, tongue and jaw apply this process with a mechanical activity. While teeth provide mechanical digestion of food, saliva chemically digests food.

YUtta and esophagus): The tongue pushes the food towards the esophagus. Meanwhile, the trachea is covered with a laryngeal lid. When swallowed food reaches the esophagus, the esophagus contracts peristaltic movements, allowing the food to move towards the stomach.

Stomach: The stomach is an organ that stores food, breaks it down mechanically and secretes enzymes to digest proteins. The secretion of gastric juice is provided by the gastrin hormone. The stomach is an acidic environment. This acid kills bacteria in food and converts proteins into amino acids in enzymes in the stomach. Ultimately, a mixture of partially digested nutrients called chyme is obtained. This mixture is sprayed into the small intestine. Vitamin B12 is a vitamin that is released from the stomach.
