Weekly Learning Objectives Describe the structure and function of the gastrointestinal tract and accessory organs of digestion, including the processes of peristalsis, mechanical and chemical digestion of food, and absorption of nutrients. Explain the concept of excretion and the excretory functions of the skin, liver, large intestine, lungs, and kidneys. Describe the layered responses of the human immune system, including both innate and adaptive immune responses, and the structures and functions of the lymphatic system. Describe the causes and types of human diseases and how they are a result of homeostatic dysfunction problems. Select ONE of the following choices. I recommend that you watch both videos because they will help you learn the material for this week. CHOICE 1 Watch the following video: Steps: Select any TWO diseases/conditions from the list below. Constipation, Gastroenteritis, Gastroesophageal Reflux (GERD), Gallstones, Celiac Disease, Crohn’s Disease, Ulcerative Colitis, Irritable Bowel Symdrome, Diverticulitis, Pancreatitis, Peptic Ulcers. 2. Describe how your disease selections affect the structure on cellular/tissue and organ levels and function (for example, describe how Gastro Esophageal Reflux Disease – GERD – acid reflux affects the structure and function of the digestive system). Please cite your references using APA format. 3. How do your diseases affect health and homeostasis? What are the signs and symptoms? CHOICE 2 Watch the following video: Write at least 300 words (total) and include all references for the following discussion points: 1) Suppose you were stuck on a raft in the middle of the Atlantic Ocean, and you have run out of all of your drinking water. Is it OK to start drinking sea water to quench your thirst? Why or why not. 2) Describe what would happen if you had kidney failure. What would happen to your homeostasis? What functions would you be missing? Are there any specific diseases or conditions that cause kidney failure? Have you or anyone in your family ever been affected by kidney failure?
