to physically see and touch the anatomy of the mammalian body rather seeing it solely in text form. This gives us a better idea of how the structures are intertwined to form the body as a whole.

that been absorbed by the human body is called digestion.Digestion is split into two different processes which are physical digestion (grounding of large molecules of food into smaller particles) and chemical digestion (enzymes released into the digestive tract use to break down large polymeric biomolecules into monomers or oligomers (dimers or trimers). Both ingestion and digestion occurs in the mouth or oral cavity(Campbell et al.‚ 2008). Physical digestion begins in the oral cavity. There are

The digestion process The digestion process begins in the mouth. First we take a bite of food. The presccence of food in the mouth stimulates the flow of saliva from the salivary glands.
