The alimentary system, or digestive system, processes food, absorbs nutrients, and eliminates waste. Key parts include:
- Mouth: Chews and mixes food with saliva.
- Esophagus: Moves food to the stomach.
- Stomach: Breaks down food with acid and enzymes.
- Small Intestine: Absorbs nutrients.
- Large Intestine: Absorbs water and forms waste.
- Rectum and Anus: Expels waste.
Accessory organs:
- Liver: Produces bile for fat digestion.
- Pancreas: Produces digestive enzymes and hormones.
- Gallbladder: Stores and releases bile.
