Lungs Anatomy Diagram Quiz

Components of the Lungs

• Apex of Lung: The topmost part of the lung, extending above the first rib. It plays a role in the lung’s overall shape and airflow.

• Superior Lobar Bronchus: The bronchus that branches from the trachea and supplies air to the upper lobe of the lung. It is crucial for effective air distribution.

• Horizontal Fissure: A separation between the right upper lobe and the right middle lobe of the lung. It enables distinct lobar functions and can be observed in imaging.

• Middle Lobar Bronchus: The bronchus that serves the right middle lobe, ensuring appropriate ventilation. It branches off from the superior lobar bronchus.

• Middle Lobe: Positioned between the upper and lower lobes of the right lung, this lobe is important for gas exchange and hosts structures for airway passage.

• Inferior Lobar Bronchus: The bronchus responsible for directing air into the lower lobe of the lung. Its patency is vital for efficient respiratory function.

• Base of Lung: The bottom part of the lung, resting on the diaphragm. It plays a critical role in expanding during inhalation and contracting during exhalation.
