Organs - Large intestine

System: Digestive

Location: Surrounding your small intestine

Physical description: 1.5 metre-long tube

Function: To convert food waste products into faeces

Making faeces

Your large intestine is the final part of your digestive tract. Undigested food enters your large intestine from your small intestine. It then reabsorbs water that is used in digestion and eliminates undigested food and fibre. This causes food waste products to harden and form faeces, which are then excreted.
