This junior high anatomy and physiology curriculum opens with the building blocks of the human body — the cells. Even the bones and muscles that give us strength and speed depend on many types of cells. Throughout the book you will learn things to do to keep your body healthy, though in a fallen, cursed world things are bound to go wrong, such as disease and injuries. As our journey though the human body progresses, it will be evident that this marvelous structure did not arise by chance. You will understand why God inspired the Psalm writer to say that the human body is "fearfully and wonderfully made"!
