Do Now Think of what you ate for breakfast today: Where did the chemical digestion of your meal start? After you eat a whole bunch of candy, which organ would secrete hormones to regulate your blood sugar level? Identify the hormone secreted.
Objective: What are the disorders of the digestive system?
Lets Review What is starch? Complex carbohydrate Long chain of DIGESTABLE plant sugars Ex: potatoes, wheat bread
Lets Review What is insulin? Hormone released from the pancreas Regulates blood sugar (glucose) level Increased insulin leads to decreases in blood sugar level
Disorders of the Digestive System Gallstones Hardened Deposits of cholesterol Occur in the GALLbladder; painful Remember this stores bile
Diarrhea Colon does not absorb enough water Infection of colon lining prevents proper absorption Can be life threatening
Constipation Too much water is absorbed from colon Very dry stool Difficult to poop
Ulcer “Peptic ulcer” Erosion of the stomach wall Stomach acid becomes very painful Ex: think of like pouring lemon juice in a cut
Diabetes When the body fails to produce or respond to insulin – blood glucose gets very high Type 1 – autoimmune; immune system attacks cells of the pancreas Type 2 – develops typically due to obesity; body does not respond to the hormone
