See-Through Sally provides a memorable visual aid for teaching human anatomy. This set consists of 12 spiral-bound anatomy charts, each representing a different area of the body, mounted on a rigid metal frame and floor stand. See-Through Sally is arranged according to both how the body presents its anatomy as if you were unlayering it, and also to correspond with how systems and organs are sequentially taught in some Human Anatomy and Physiology classes. Students can understand how the body systems work together as they turn from page to page. The initial page starts with the regions of the body, cavities, anterior and posterior quadrants and what organs fall into those areas. It begins with the outer layer of the body, and continues through the lymphatic, muscular, vascular, skeletal, nervous, respiratory, heart, digestive, urinary, reproductive, and endocrine systems.
