Created by a homeschooling pediatrician, this new anatomy curriculum from Master Books focuses on the wonders of the human body systems. The “real books” are filled with solid, scientific information, thought-provoking stories, and a strong Christian worldview.  

The levels are divided by the quantity of material mastered. Although the series is designed for upper elementary students, younger children can be included because of these levels.  Full-color illustrations and photographs.  The readers are considered the Student Books for the curriculum.

This second book in the series covers the respiratory system, focusing on the structures, function, diseases, and God's efficient and effective design.
