Where the trachea is, in 3D
The trachea is the airway from the neck into the chest. It divides into the left and right bronchi. It belongs to the respiratory system. It begins below the larynx at the cricoid cartilage and is about 10 to 12 cm long. Sixteen to twenty C-shaped rings of cartilage, open at the back, hold it open, and the split usually lies at the level of the fourth or fifth thoracic vertebra.
Frequently asked questions
Which body system does the trachea belong to?
The trachea 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 trachea?
The BAHI BODY 3D model of the lungs also shows the right upper lobe, right middle lobe, right lower lobe, left upper lobe and left lower lobe.
Where are the lungs?
The lungs are the breathing organs on either side of the chest.
How do the right and left main bronchi differ?
The right main bronchus is shorter, wider and more vertical than the left.
