Every year, I go to my doctor for my annual physical. My doctor goes through a standard series of procedures every time. He asks me questions about my diet and my general physical well-being. He puts his cold stethoscope to my chest and listens to my heart and breathing. He checks my blood pressure and heart rate. His lab technician takes samples of blood for tests to collect information related to organs like my liver and pancreas. He may even request tests depending on what he has learned during the exam. Later, my doctor follows up to discuss the results.
