The intestines

The video explains the digestive process focusing on the intestines. It describes the small intestine's role in further digesting food and absorbing nutrients, aided by chemicals from the liver and pancreas. The large intestine processes undigested food, absorbs water, and expels waste. The small intestine is longer but narrower than the large intestine, and food takes about 3 hours to pass through it, while the large intestine takes about 30 hours to process waste.
