Ever wondered how the heart works? What does blood do anyway? Why are there different blood types? Who can donate blood, and how does it work? If you've ever wondered about any of these questions, this is the class for you! We'll begin with an explanation of the physiology of blood and the cardiovascular system—how it works normally, what can go wrong, and how it differs between people. Then, we'll discuss blood donation and transfusion—the process, the biomedical blood supply, and scientific and ethical considerations of regulation—as well as any other questions or topics brought up by you!
