Describe disorders and the treatment of disorders linked to organs of the digestive system and their effect on the homeostasis of the system and the organism as a whole. Include: a. Ulcers b. Gall stones c. Ileitis/colitis 30. Evaluate how nutritional deficiency and starvation diets such as bulimia and anorexia nervosa can adversely affect the dynamic equilibrium. 31.
