The human lung with heart and larynx model is a seven-part three-dimensional representation of the respiratory and cardiovascular systems in the human body. The model typically includes the two lungs, the heart, the trachea, and the larynx.

The lungs are the primary organs of respiration, and the heart is responsible for circulating blood throughout the body. The trachea and larynx are part of the airway system that connects the lungs to the outside environment. The model is used in medical education to help students and healthcare professionals understand the anatomy and physiology of the respiratory and cardiovascular systems and their interrelated functions.

The model may also be used in the development and testing of medical devices and procedures related to lung and heart health. The seven-part model allows for a detailed study of each individual component and how they work together to sustain life.
