"The human body relies on the coordinated activity of a number of body systems. This video looks at the systems that deliver oxygen and nutrients to our tissues, and remove waste products such as carbon dioxide. Using a unique combination of pig organ dissection and clear, informative graphics and animation, it provides a fascinating insight into the way our bodies function. The systems examined are, the cardio-vascular or circulatory system (heart & blood vessels), the respiratory system, the gastro-intestinal or digestive system and the excretory or urinary system"--Container.
