GED® Science: Human Body Systems & Health (Deep Dive)

A deep dive into how the human body is built and kept alive, expanding the single 'Human Body Systems' lesson from the GED® Life Science course into a full mini-course. You'll see how cells build up into organ systems, meet the major systems and their jobs, follow oxygen and nutrients to your cells, learn how the body senses and moves, understand nutrition, and explore how disease spreads and how the body and public health defend against it. Plain language, all-new labeled diagrams, common-misconception warnings, and GED®-style practice with full explanations.
