11. Digestive System

The digestive system comprises various organs that work collectively to break down food into simpler components for nutrient absorption. The process involves ingestion, mechanical and chemical digestion, absorption of nutrients, and egestion of waste. Key organs include the mouth, stomach, small intestine, large intestine, liver, and pancreas, each contributing crucially to digestion and nutrient processing.
