The Interactions DVD provides an interactive examination of physiological processes within each system of the body using animations and interactivity to enhance understanding. At the heart of Interactions is a focus on core principles - homeostasis; communication; energy flow; fluid flow; and boundaries--that underscore the essential relationships between structure and function as well as interrelationships between systems. It is the reinforcement of these fundamental organizing principles, to which a variety of processes and concepts for each system will be attached, that sets this product apart.Body Systems Covered: Foundations; Regulation: The Nervous and Endocrine Systems; Support and Movement: The Skeletal and Muscular Systems; Distribution: The Cardiovascular and Lymphatic Systems; Disease Resistance: The Immune and Lymphatic System; Energy Acquisition and Use: Metabolism and the Digestive System; Gas Exchange and pH Balance: The Respiratory System; Balancing Fluids and pH: The Urinary System
