The Gastrointestinal System


            Glossary


            Amebiasis
                  An inflammation if the intestines caused by infestation with Entameba histolytica (a type of
                  ameba) and characterized by frequent loose stools flecked with blood and mucus


            Amylase
                  An enzyme produces in the pancreas and salivary glands that help in the digestions of starches.

            Bile
                  A bitter, alkaline, brownish-yellow or greenish-yellow fluid that is secreted by the liver, stored in
                  the gallbladder, and discharged into the duodenum and aids in the emulsification, digestion, and
                  absorption of fats. Also called gall.


            Biotin
                  Biotin is used in cell growth, the production of fatty acids, metabolism of fats, and amino acids. It
                  plays a role in the Krebs Cycle. Biotin is also helpful in maintaining a steady blood sugar level. It
                  is often recommended for strengthening hair and nails.

            B12
                  A vitamin important for the normal formation of red blood cells and the health of the nerve
                  tissues. Undetected and untreated B12 deficiency can lead to anemia and permanent nerve and
                  brain damage

            Candida Albicans
                  Found in animals and in man. Has been isolated from the skin and mucosa of man, but has also
                  been recovered from leaves, flowers, water, and soil. Reported to be allergenic. A common cause
                  of superficial infection, oral and vaginal infection, sepsis, and disseminated disease. Cells from
                  the organism are usually not airborne and are considered to be normal component of the flora of
                  the mouth and other mucous membranes on the body.

            Chemical digestion
                  Is a chemical breakdown of food when being in the mouth (oral cavity). Is the digestive
                  secretions of saliva that moistens food and introduces gastric juices and enzymes that are
                  produced in the stimulation to certain macronutrients, such as, carbohydrates. In this, the mouth
                  saliva carries an enzyme called amylase for breaking down carbohydrates.


            Cholecystokinin (CCK)
                  Cholecystokinin (also called pancreozymin), this is a hormone in the small intestinal cells
                  (intestinal mucosa) that is produced in response to food. This hormone regulates the release of
                  secretions of many organs that aid digestion, such as, bicarbonate from the pancreas to reduce the
                  acidity of digestive juices like the chyme that enters the small intestine form the stomach that
                  contains hydrochloric acid (HCL).


            Chylomicrons
                  The lipoproteins first formed after absorption of lipids form food.

            Chyme
                  The thick semi fluid mass of partly digested food that is passed from the stomach to the


                                                                                                Wikibooks | 239
