Anatomically, the model shows the entire respiratory system starting from the throat (oral cavity, nasal cavity and pharynx are not included). The following items are displayed:
Throat
The trachea and bronchial tree
The heart
Diaphragm
The throat (larynx) is shown with its various cartilages and membranes, as well as their relationships to the bone of the tongue (os hyoideum) and the thyroid gland (glandula thyroidea).
The model shows the division of the trachea into main bronchi, lobe bronchi and segmental bronchi. Likewise, it is seen how A. pulmonalis and V. pulmonalis follow the bronchial tree into the lung tissue.
The heart is imaged with all the vessels that run respectively to and from the heart and the coronary arteries. All four chambers of the heart are visible, as well as the valves located between the atria, ventricles and outflow vessels (respectively A. pulmonalis and aorta).
In addition, it is seen how the lungs and heart rest on the diaphragm, and how the oesophagus, aorta and inferior vena cava pass through each of their openings in the diaphragm on their way down into the abdominal cavity.
