Mouth
Mouth
The start of mechanical and chemical digestion. Teeth break down food physically, while saliva breaks down food molecules.
Esophagus
Esophagus
Muscular tube connecting the mouth to the stomach; uses peristalsis to move food.

Study Notes
- Organs have specific roles in the digestive system, from initial breakdown to waste elimination.
Mouth
- Digestion begins in the mouth, using both mechanical and chemical processes.
- Mechanical digestion involves the physical breakdown of food by teeth, which increases surface area.
- Chemical digestion starts with saliva, which breaks down food molecules.
Esophagus
- The esophagus is a muscular tube connecting the mouth to the stomach.
- Peristalsis, the muscular contraction, moves food down the esophagus.
Stomach
- Mechanical digestion is prominent in the stomach
- Some chemical digestion occurs with digestive juices, including enzymes and acids, aiding the process.
Small Intestine
- Most chemical digestion occurs in the small intestine.
- Nutrients from digested food are absorbed into the bloodstream in the small intestine.
Large Intestine
- The large intestine absorbs water into the bloodstream, concentrating undigested material.
- Remaining undigested material is prepared for elimination from the body
Rectum
- The rectum compresses waste material into solid form, ready for elimination.
