Unformatted text preview: For information on the normal functioning of the central nervous system, please refer to The Brain/ Central Nervous System 3a(ii) (pg.131 140) of your text. By no means are you expected to memorize everything in the chapter, but you will likely find it to be a great resource for definitions and figures to help orient yourself when reading more complex discussions of depression. 12 H. PYLORI You have been assigned Helicobactor pylori (H.pylori) infection for your independent research project. Before you can begin to uncover how H.pylori develops or how it can be treated, you must first understand the normal function of the upper gastrointestinal tract and immune system. A simplified overview of general biology pertinent to this complex disease has been compiled for you so that you may become familiarized with some of the terminology and key aspects of the disease. The information was gathered primarily from the MedPrep, Biology On ­ line, the National Institute for Health and the National Institute for Ageing and reflects a basic level of detail. Be sure to read and understand this information before beginning your research. The Non Diseased (Normal) State (b) The Healthy Upper Gastrointestinal (GI)Tract For information on the basics of the healthy digestive system please refer to Chapter 3b (ii), The Digestive System, pages 239 255. Pay particular attention to pages 239 241 (four basic layers/tissues of the GI tract) and pages 244 248 (the esophagus, stomach, and small intestine). By no means are you expected to memorize everything in the chapter, but you will likely find it to be a great resource for definitions and figures to help orient yourself when reading more complex discussions of H.pylori. (c) The Healthy Immune System For information on biological cell defense/immune response, please refer to 3a(v) The Local Support & Defense System (p.182 197) in your text. Pay particular attention to pages 182 186. By no means are you expected to memorize everything in the chapter, but you will likely find it to be a great resource for definitions and figures to help orient yourself when reading more complex discussions of H.pylori infections. (c)The Basics of a Bacterium Bacteria are unicellular (microscopic) prokaryotes which lack membrane bound organelles like mitochondria, golgi apparatus and endoplasmic reticulum. Bacteria range in size from 0.15 to 4 micrometers. Bacteria are found in soil, in water, and in the air. They are also found on plants, on the surfaces of decayed or decaying matter, and in the digestive and reproductive tracts of hu...
