Giant Hands-On Heart

Twice the size of an adult heart, and nearly three times that of a child, this rugged, vinyl reproduction will withstand years of hard usage by enthusiastic students. Because of its ample proportions, even fine details are plainly visible and readily investigated. Nonbreakable, it’s easy to handle and pass around the classroom. Three hinged doors through the heart wall swing open to let your students explore the four pumping chambers. Metal hinges are bonded into the model - no screws to become stripped or work loose with usage. Flexible plastic valves help your students visualize the one-way course blood flows through the heart. So that students may understand its intimate orientation with other thoracic organs, a segment of the windpipe (trachea) and esophagus is presented on the back side of the heart. Supported by its wooden pedestal, the heart will pivot 360° for viewing from all aspects, or lift off for pass-around investigation. A seven-page study guide explains the physiological function of each of the 39 features number coded on the model. Overall dimensions on base: 7 in. x 7 in. x 15 in.
