The Human Body: How We Fail, How We Heal

Your body is a fortress under constant assault. Infectious diseases, parasites, environmental toxins, physical trauma, allergens, and natural disasters are some external enemies it faces. From the inside, it is threatened by the cellular mutations that produce cancer. Fortunately, the body's defenses are remarkably successful, and most of the time we are unaware of the intense drama taking place within our cells and organs. This course explores the many ways the body meets the challenges of disease and injury with remarkable defenses and restorative powers, and how, in some cases, it may either overreact or fail.
