When it comes to the human body, there's no lack of digital products that explore its inner workings. DK The Human Body takes high school students system-by-system through the body via labeled illustrations and a few animated scenes and videos. The Heart and Lungs Lab (isygmes S. C.) for middle grades can be adapted to different learning levels and styles and is available in both Spanish and English. Tinybop's Human Body for elementary students has no text beyond labels, but offers interactive features and an extensive online guide in 10 languages. Zybright's app, reviewed below, has a few additional features.

Screen from My Incredible Body (Zybright) "The Lung"

Viewers will be fascinated by the digitally enhanced look inside the human body displayed in My Incredible Body (Zybright, iOS, $9.99; Android, $9.99; also available for Windows touch devices, $4.99, PCs and Macs; various in-app purchases, $.99; Gr 4-7). Pulmonary function, the digestive system, skeletal and muscular anatomy, the kidneys and waste processing, the heart and circulatory system, along with the brain and nervous system all receive attention. One segment touches on sensory conception and autonomic functions such as breathing and swallowing. The lymphatic and endocrine systems are not covered. Upon opening the app, students can choose from eight animated icons; an eye represents the senses, a pulsating heart, circulation, etc. A tap to any of these icons will bring students to a core, 3-D model of the specified organ or system and additional animated icons that lead to more 3-D perspectives, illustrations, and text features. A quiz feature/icon—is activated through an in-app purchase. The quizzes will add real value to those using the app for review or study purposes.

As students travel through the body part or system, stops along the way offer close-up views featuring colorful, detailed visuals with occasional labels, and text boxes offering basic anatomy information and vocabulary. Big- picture illustrations offer a silhouette of the body on the side with illuminated dot(s) indicating the of the body part(s) under discussion. The text boxes are narrated, but students can switch off the narration if they choose. An icon depicting a rocket allows users to literally travel through the organ or system—transported inside the arteries and veins in the case of the circulatory system, or through the nose, down the larynx and windpipe, and into the lung (then back out) for the respiratory system. The app utilizes a scalable model of the human body with zoom and pinch capabilities. On certain screens, digital overlays can be switched on or off. The section on puberty is another in-app purchase. It includes 3-D images and brief, separate segments on the male and female reproductive systems, conception, the penis, and the uterus. While large in file size, this introductory app is glitch-free and its images will stand out gloriously on a large display or projected screen. Students looking for a way to spruce up their anatomy science fair projects will gain extra points with this great, hands-on, interactive demonstration of the human body. A must-have for educators and students interested in the life sciences. Additional information, a tutorial, and a trailer are available on the Zybright website.—Krista Welz, North Bergen High School Media Center, NJ Eds. note: For additional apps on the human body, see "The Human Body—Animated" For additional app reviews on a range of topics, visit SLJ's dedicated app webpage.
