Question

Where does Digestion begin?

Answer 1

Human digestive system

1. To transfer energy from food to the body, a number of components make up the digestive system in humans.
2. The gastrointestinal tract and supporting organs including the liver, pancreas, and gallbladder make up the digestive system.
3. The mouth, stomach, esophagus, small intestine, and large intestine, which house the rectum and anus, are examples of hollow organs that make up the gastrointestinal system (GI tract).
4. Beginning of Digestion:

• The salivary glands create saliva, a digestive liquid that helps food flow more readily past the esophagus and into the stomach by moistening it.
• The digestive process begins in the mouth when a person chews.
• Additionally, saliva includes an enzyme that initiates the breakdown of food's carbohydrates.
• Saliva facilitates meal digestion and helps with the breakdown of carbohydrates.
• The meal is given in the form of a bolus, which is a little circular lump of slurry.
• The bolus travels by peristalsis from the mouth to the stomach.
• The stomach wall might be harmed by the pepsin and hydrochloric acid secretions.
