Where the left upper lobe is, in 3D
The left upper lobe is the top of the two lobes of the left lung, which has only two lobes to make room for the heart; the model traces it through its bronchial branches. It lies above and in front of the oblique fissure. Its front edge has the cardiac notch, where the heart sits, and below it a tongue-shaped projection called the lingula.
Frequently asked questions
Which body system does the left upper lobe belong to?
The left upper lobe belongs to the respiratory system. The respiratory system is the airway that starts at the nose and mouth and runs through the pharynx, larynx and trachea into the bronchi and lungs.
What else can you see alongside the left upper lobe?
The BAHI BODY 3D model of the lungs also shows the trachea, right upper lobe, right middle lobe, right lower lobe and left lower lobe.
Where are the lungs?
The lungs are the breathing organs on either side of the chest.
Why does the left lung have only two lobes?
The heart lies mostly left of the midline, so the left lung has a cardiac notch and no horizontal fissure, leaving just an upper and a lower lobe.
