Anatomical model

The image shows an anatomical model representing the human heart and lungs. 

- *Lungs*: The lungs are represented in detail with an external surface that highlights the bronchial ramifications and the alveolar structure, indicated by a reticular design. The model is divided into two main lobes (right and left lung). Each lung shows a natural-looking appearance, with orange and red hues highlighting the blood vessels.

- *Heart*: The heart is visible between the two lungs. Although the representation is schematic, you can see the main arteries emerging from the top of the heart and extending towards the lungs. The blood vessels are colored to distinguish arteries and veins.

- *Trachea*: The trachea is represented in the upper part of the model. Note the tracheal rings (in blue), which are typical of the cartilaginous structures that keep the trachea open.
