The model shows an external pulmonary lobe with a magnification of 130x. The following are represented:

• Segmental bronchus and its terminal branches (bronchioles)
• Alveolus opened on the right side
• Pulmonary vessels and their capillary networks
• Branch of a bronchial artery
• Pulmonary pleura
• Connective tissue septum on the left side
