Physical and Chemical Changes during the Digestive process

• Ingestion: Is the process of taking food products beverages or medicines into your mouth and swallowing them.
• Chemical change: occurs when the enzymes from saliva chemically breaks down the carbohydrates in the food as you chew
• Deglutition: the action or process of swallowing
• Digestion: The process of breaking down large molecules into smaller molecules.
• Mechanical digestion: The process of breaking down food into smaller pieces using teeth and muscles.
• Chemical digestion: The breakdown of large molecules into smaller molecules by chemical reactions.
• Absorption: takes place within the small intestine.
• columnar epithelium: the outer covering of the villi, wraps around and protects the capillaries and lymphatic nerves
• The blood capillaries surround a lymphatic vessel called "lacteal" which absorbs fat molecules passing through the intestines
• Assimilation: is a chemical process that refers to the movement of digested food molecules and nutrients into the cells of the body
• Elimination or Egestion: Is the final step of the digestive process.
