The Journey of Food Through the Digestive Tract
**Mouth:** It all begins here, where food is ingested and mechanically broken down
1.
by chewing. Saliva, containing the enzyme amylase, starts the chemical digestion of
carbohydrates.
**Esophagus:** A muscular tube that transports food from the mouth to the
2.
stomach via peristalsis (wave-like muscle contractions).
**Stomach:** This organ further mechanically churns food and mixes it with gastric
3.
juices containing hydrochloric acid and pepsin, initiating protein digestion.
**Small Intestine:** The primary site for digestion and absorption. Enzymes from the
4.
pancreas and bile from the liver aid in breaking down fats, carbohydrates, and
proteins. Nutrients are absorbed through the intestinal walls into the bloodstream.
**Large Intestine:** Absorbs water and minerals, forming solid waste.
5.
**Rectum & Anus:** Waste is stored and then expelled from the body.
