This life-size, 7-part model presents a complete and detailed representation of the human respiratory system. It includes a sagittally sectioned larynx, frontally sectioned lungs, and a 2-part heart for clear visualization of internal structures. The model accurately demonstrates the arrangement and function of respiratory organs, making it an effective tool for understanding breathing mechanisms and organ relationships. Mounted on a board, it is ideal for teaching, demonstration, and anatomical study.
