You live with it 24 hours a day, but how well do you really know it? This course is an owner's manual to a remarkably complex, resilient, and fascinating structure: the human body. Using detailed color illustrations, life-sized models, and, even a video shot during surgery, this course examines the major systems of the body, explaining exactly how things work and why they sometimes don't. Each lecture concentrates on a particular organ or organ system, beginning with the cardiovascular system, and on through the respiratory, nervous, digestive, endocrine, urinary, reproductive, musculoskeletal, and immune systems. The last also investigates the biology of cancer. This course introduces anatomy and correlates the findings in anatomy with the functioning of the normal human body, its physiology.
