1) Ingestion - The intake of food. The mouth is responsible for this function, as it is the orifice through which all food enters the body.
2) Secretion - The secreting of fluids such as saliva, mucus, hydrochloric acid, enzymes, and bile.
3) Mixing and Movement - Composing of 3 processes: Swallowing, Peristalsis, and Segmentation
4) Digestion - process of turning large pieces of food into its component chemicals. Mechanical digestion is the physical breakdown of large pieces of food into smaller pieces. Chemical digestion begins in the mouth with salivary amylase in saliva splitting complex carbohydrates into simple carbohydrates.
5) Absorption - Once food has been reduced to its building blocks, it is ready for the body to absorb. Absorption begins in the stomach with simple molecules like water and alcohol being absorbed directly into the bloodstream.
6) Excretion - The final function of the digestive system is the excretion of waste in a process known as defecation. Defecation removes indigestible substances from the body so that they do not accumulate inside the gut.
