Study Notes
Components of the Digestive System
- Mouth: consists of teeth, tongue, and salivary glands
- Esophagus: muscular tube that carries food to the stomach
- Stomach: muscular sac that secretes digestive enzymes and acids
- Small intestine: long, thin tube where most nutrient absorption occurs
- Liver: produces bile to break down fats
- Pancreas: produces digestive enzymes
- Gallbladder: stores bile from the liver
- Large intestine (colon): absorbs water and electrolytes
- Rectum: stores feces until eliminated through the anus
Processes of the Digestive System
- Ingestion: taking food into the mouth
- Mechanical digestion: breaking down food into smaller pieces (chewing, grinding)
- Chemical digestion: breaking down food into smaller molecules (enzymes, acids)
- Absorption: nutrients absorbed into bloodstream through intestinal walls
- Elimination: waste products eliminated from the body through the anus
