The primary airway branch arising from the tracheal bifurcation that conducts air into the left lung.
Situated in the thoracic (chest) / upper limb region (midline / bilateral aspect, central plane) within the respiratory.
Jump directly to connected anatomical structures to compare their locations, functions, and 3D relationships.
Breathing depends on pressure changes produced by respiratory muscles, principally the diaphragm and intercostal muscles.
The right ventricle pumps blood to the lungs for oxygenation, and pulmonary veins return oxygenated blood to the left atrium.
Cartilage rings and elastic ligaments keep the trachea and laryngeal airways open during pressure changes.
