A chart displaying all major organs of the human body. Did you know that your heart is about the size of your closed hand? The descriptive and informative chart is a great visual tool for students to learn about the major organs in our system, including the cardiovascular system, respiratory system and digestive system. The chart clearly displays how blood which is lacking oxygen is collected from everywhere in the body and travels to the right atrium, to be transported to the lungs. In the lungs, the blood will lose waste and it collects oxygen. The now oxygen rich blood is moved back into the left atrium of the heart. From there, it will be pumped into the aorta to travel to the rest of the body, where the oxygen will be used. All parts of the cardiovascular system, respiratory system and digestive system are clearly labelled and simply illustrated, to avoid confusion and to make the systems as clear as possible. Great for classroom display. The laminated chart measures 69.5 x 49.5cm.
