Pancreas
Pancreas Two cell types to produce: 1. 2. exocrine acini produce: islets of Langerhans produce: 1 – 2% of pancreas are the islets of Langerhans
Islets of Langerhans Two hormones are produced: 1. beta cells: 2. alpha cells: blue = cell nuclei green = insulin red = glucagon
Insulin Function When is insulin released? after eating hyperglycemia decreased blood sugar beta cells increased glucose uptake glycogen production in liver cellular signals for insulin release
Glucagon Function What does glucagon do? breaks down glycogen hypoglycemia increased blood sugar alpha cells glucose release from liver glucose production in liver cellular signals for glucagon release
Blood Sugar Diseases Three types of diabetes: 1. Diabetes Mellitus - Type 1 2. Diabetes Mellitus - Type 2 3. Diabetes Insipidus
Diabetes Mellitus – Type I also known as: Cause � Symptoms � Treatment �
Diabetes Mellitus – Type II formerly known as: Cause � Symptoms � � Treatment � �
Diabetes Insipidus Cause � Symptoms � � � Treatment �
Canadian Connection Frederick Banting & Charles Best �Nobel Prize – 1923 �insulin isolation �tied off ducts to digestive tract �cell producing digestive enzymes shrivelled �only islets of Langerhans remained
