Digestive and Urinary System Lesson 1: The Digestive System Terms: q  Ã‚  Ã‚  Ã‚  Ã‚  Digestion: q  Ã‚  Ã‚  Ã‚  Ã‚  Absorption: q  Ã‚  Ã‚  Ã‚  Ã‚  Elimination:  Ã‚  Ã‚  Ã‚  Ã‚   q  Ã‚  Ã‚  Ã‚  Ã‚  Mastication: q  Ã‚  Ã‚  Ã‚  Ã‚  Peristalsis: q  Ã‚  Ã‚  Ã‚  Ã‚  Gastric Juices: q  Ã‚  Ã‚  Ã‚  Ã‚  Bile: Functions of the Digestive System: q  Ã‚  Ã‚  Ã‚  Ã‚  Digestion, Absorption, and Elimination. q  Ã‚  Ã‚  Ã‚  Ã‚  Digestion occurs in the digestive tract which includes: 1.  Ã‚  Ã‚  Ã‚  Ã‚  Mouth: Mastication occurs and enzymes produced by salivary glands starts digesting carbohydrates. 2.  Ã‚  Ã‚  Ã‚  Ã‚  Esophagus: 10 in. long and extends from the pharynx to the stomach. Food moves down the esophagus by the peristalsis. The sphincter, a circular muscle at the entrance of the stomach opens and closes to allow food to enter the stomach. 3.  Ã‚  Ã‚  Ã‚  Ã‚  Stomach: Holds about 1qt of food for 3-4 hours and controls the rate at which it enters the small intestine. It also produces Chyme and Gastric Juices. 4.  Ã‚  Ã‚  Ã‚  Ã‚  Small Intestine: 20ft (6m) long, 1in (2.5cm) in diameter. Consist of 3 parts the duodenum, the jejunum, and the ileum. Intestinal juice, secretions from the liver and pancreas complete chemical breakdown. 5.  Ã‚  Ã‚  Ã‚  Ã‚  Large Intestine (Colon): 2.5in (6cm) in diameter and 5-6ft (1.5-1.8m) long. The main function of the large intestine is the elimination of waste and the absorption of water. The water is absorbed into the bloodstream Other Organs that aid Digestion q  Ã‚  Ã‚  Ã‚  Ã‚  The liver, gallbladder, and pancreas are essential for the digestion of carbohydrates, proteins, and fats. 1.  Ã‚  Ã‚  Ã‚  Ã‚  Liver: the largest gland in the body q  Ã‚  Ã‚  Ã‚  Ã‚  Weighs about 3.5 lbs. q  Ã‚  Ã‚  Ã‚  Ã‚  Dark reddish brown color q  Ã‚  Ã‚  Ã‚  Ã‚  Over 500 functions q  Ã‚  Ã‚  Ã‚  Ã‚  Produces bile q  Ã‚  Ã‚  Ã‚  Ã‚  Converts sugar glucose to glycogen and stores it q  Ã‚  Ã‚  Ã‚  Ã‚  Maintains level of glucose in the blood q  Ã‚  Ã‚  Ã‚  Ã‚  Changes harmful to less harmful toxins q  Ã‚  Ã‚  Ã‚  Ã‚  Stores vitamin A, D, E, K, B12, and Iron 2.  Ã‚  Ã‚  Ã‚  Ã‚  Gallbladder: Small sac about 3-4 in. (7-10cm) long q  Ã‚  Ã‚  Ã‚  Ã‚  Stores bile until food moves from the stomach into the duodenum of the small intestine. 3.  Ã‚  Ã‚  Ã‚  Ã‚  Pancreas: a gland of the digestive and endocrine system. q  Ã‚  Ã‚  Ã‚  Ã‚  Produces insulin q  Ã‚  Ã‚  Ã‚  Ã‚  Produces 3 digestive enzymes: 1.  Ã‚  Ã‚  Ã‚  Ã‚  trypsin: digest protein 2.  Ã‚  Ã‚  Ã‚  Ã‚  amylase: digest carbohydrates 3.  Ã‚  Ã‚  Ã‚  Ã‚  lipase: digest fats q  Ã‚  Ã‚  Ã‚  Ã‚  These enzymes are released into the small intestines through ducts. Lesson 2: Problems and care of the Digestive Systems Terms: q  Ã‚  Ã‚  Ã‚  Ã‚  Indigestion: q  Ã‚  Ã‚  Ã‚  Ã‚  Hiatal hernia: q  Ã‚  Ã‚  Ã‚  Ã‚  Gallstones: q  Ã‚  Ã‚  Ã‚  Ã‚  Peptic ulcers: q  Ã‚  Ã‚  Ã‚  Ã‚  Gastritis: q  Ã‚  Ã‚  Ã‚  Ã‚  Appendicitis: q  Ã‚  Ã‚  Ã‚  Ã‚  Hepatitis: Common Functional Problems: q  Ã‚  Ã‚  Ã‚  Ã‚  Halitosis: (bad breath), can result from disorders of the teeth and gums caused from poor oral health care. q  Ã‚  Ã‚  Ã‚  Ã‚  Indigestion: occurs when your body doesn’t properly breakdown foods. This can be caused by eating too much ,eating too fast, or by indulging in an excess of alcohol. q  Ã‚  Ã‚  Ã‚  Ã‚  Heartburn: occurs when acid content from the stomach backs up into the esophagus. If a person has hiatal hernia they may experience heartburn. q  Ã‚  Ã‚  Ã‚  Ã‚  Gas: a certain amount of gas in the stomach or intestine is normal but some foods can cause an excess of gas. q  Ã‚  Ã‚  Ã‚  Ã‚  Nausea and Vomiting: this can be caused by motion, pathogens, medicines, drugs, and other substances in the stomach. Nausea precedes vomiting. Vomiting is reverse peristalsis.
