human blood circulatory system working model heart lungs 3d science exhibition craftpiller

Human blood circulatory working model 3D, in this course offers an interactive way to understand how blood flows through the human body. Learners are guided to build a detailed 3D model that demonstrates the movement of blood between the heart, lungs, and the rest of the body. The course explains the two main circuits—pulmonary circulation, where blood is oxygenated in the lungs, and systemic circulation, where oxygen-rich blood is delivered to body tissues. Students will recreate essential components such as the heart chambers, arteries, veins, and capillaries using simple materials like cardboard, pipes, balloons, and colors to represent oxygenated and deoxygenated blood. This hands-on approach helps learners visualize the continuous cycle of blood flow, the role of valves in preventing backflow, and how oxygen and nutrients are transported to cells. The project also introduces common circulatory system disorders and emphasizes the importance of heart health. Perfect for school and college science projects, this course combines creativity with scientific learning, making biology engaging, practical, and memorable. howtofunda
