Oesophagus: Muscular tube transporting food to the stomach via peristalsis.
Stomach: Stores food, mixes with gastric juices, and initiates protein digestion.
Small Intestine: Primary site of nutrient absorption; further digestion occurs here.
Large Intestine: Absorbs water and electrolytes; forms and stores faeces.
Rectum: Stores faeces until elimination.
Anus: Exit point for faeces.
