Digestion: The mechanical and chemical breakdown of food in subunits so that nutrients can be absorbed. Ingestion: The act of taking food into the mouth. Digestive Tract: The central pathway of the digestive system; a long muscular tube the pushes food between the mouth ant the anus, Salivary Glands: Glands that secrete enzymes, including salivary amylase, which digests carbohydrates, into the mouth. Tongue: A muscular organ in the mouth that aids in swallowing Esophagus: The section of the digestive tract between the mouth and the stomach Peristalsis: Coordinate muscular contractions that force food down the digestive tract. Stomach: An expandable muscular organ that stores, mechanically breaks down, digests proteins in food. Pepsin: A protein-digesting enzyme that is active in the stomach Chyme: The acidic :soup"of partially digested food that leaves the stomach and enters the small intestine. Small Intestine: The organ in which the bulk of chemical digestion and absorption of food occurs. Duodenum: The first portion of the small intestine; the duodenum receives the chyme from the stomach and mixes it with digestive secretions from other organs Pancreas: An organ that helps digestion by producing enzymes (lipase) that act in the small intestine, secretes a juice that neutralizes acidic chyme. Liver: Aids digestion by producing bile salts and emulsifying fats. Bile salts: Chemicals produces by the liver an stored by the gallbladder that emulsify fats s they can be chemically digested by enzymes Emulsify: To break up large fat globules into small fat droplets that can be more efficiently chemically digested by enzymes. Gallbladder: Organ that stores bile salts and releases them as needed into the small intestine. Lipase: A fat-digesting enzyme active in the small intestine Epithelial cells: cells that line organs and body cavities; in the digestive tract to absorb nutrients. Absorption: The uptake of digested food molecules by the epithelial cells lining the small intestin Villi: Finger-like projections or folds in the lining of the small intestine that are responsible for nutrient absorption and water absorption Large intestine: Remaining water is absorbed and solid stool is formed. Colon: The first and longest portion of the large intestine, water absorption. Stool: Solid waste material eliminated form the digestive tract. herniawww.webmd.com A hernia occurs when an organ pushes through an opening in the muscle or tissue that holds it in place. For example, the intestines may break through a weakened area in the abdominal wall. Hernias are most common in the abdomen, but they can also appear in the upper thigh, belly button, and groin areas. body mechanicsulcer
