The Alimentary Canal Explained

The process of digestion is systematically explored, detailing how food transforms into waste. Initially, food is chewed and converted into a bolus before descending into the stomach, where it mixes with acidic juices to create a mushy substance. This mixture is then released into the small intestine, where the body absorbs most of its nutrients and proteins. The remaining material travels to the large intestine, where water is extracted, ultimately forming fecal matter from what is left behind.
