Linking Four Organ Systems to Understand Diabetes Ketoacidosis (DKA) in Human Anatomy and Physiology Class
Diabetic ketoacidosis (DKA) occurs in type I diabetes due to inadequate amount of insulin levels. Human body systems work together with specific functions to keep us healthy. Anatomy and Physiology II Students at Gordon State College learned each four organ systems separately, namely endocrine, cardiovascular, respiratory and urinary. Components of DKA comprise of hyperglycemia, ketoacidosis, ketonuria, hypokalemia and osmotic diuresis. Students dissected four of each organ systems to understand the components of DKA and presented their posters. Students were evaluated on their understanding of pathophysiology of DKA by linking four organ systems. We are currently developing a new pedagogy of the modules for the students to put these four organ systems together, resulting in body functions of alleviating the symptoms of DKA, such as nausea, vomiting, dehydration, volume depletion, blood pressure depression and Kussmaul respiration etc. Students have to develop their critical thinking skills to connect the four organ systems for the overall cause of DKA. This new pedagogy will provide the students for deeper understanding of human physiology from the simple memory of information into the systems approach. The design of the pedagogy will be discussed.
