Digestive System

Alimentary canal (~9 m, mouth to anus) plus accessory organs (liver, gallbladder, pancreas). Performs mechanical/chemical digestion, nutrient absorption, water reabsorption, and waste excretion. Enteric nervous system (~100M neurons) provides semi-autonomous regulation.

Also known as: gastrointestinal system, GI system, alimentary system
