Course Description

Human respiratory system model 3D, in this course is designed to give students a clear and practical understanding of how the respiratory system works in our body. In this course, learners will build a 3D model that demonstrates the structure and function of organs such as the nose, trachea, lungs, diaphragm, and alveoli. Using simple materials like balloons, straws, plastic bottles, and cardboard, students will create a functional model that shows how air enters the lungs, how the diaphragm moves during inhalation and exhalation, and how oxygen is exchanged with carbon dioxide. Step by step, the course explains the breathing process and the importance of each organ involved in respiration. This project makes complex biology concepts interactive and easy to visualize, while also encouraging creativity and problem-solving skills. Ideal for school science projects, classroom demonstrations, and exhibitions, the course bridges theory with hands-on learning. By the end, participants will have a working 3D model that not only illustrates the human respiratory system but also deepens their knowledge of how breathing sustains life. howtofunda
