The human respiratory system model is a three-dimensional representation of the respiratory system in the human body. It typically shows the different components of the system, including the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs. The model may also show the diaphragm, which plays a critical role in the breathing process.

The respiratory system model is used in medical education to help students and healthcare professionals understand the anatomy and physiology of the respiratory system and its function in the body. The model may also be used in scientific research to study respiratory diseases and conditions and to develop new treatments and therapies.

The human respiratory system model may come in different sizes, colors, and materials, depending on the intended use and can range from life-size to magnified representations.
