Lung Apices Definition
The lung apices are often referred to as the apical zone of the lungs or the lung apex. That is because, as the name suggests, this is the top or highest part of the lungs. In general, the upper lobes are overventilated compared to the lower lobes which tend to have more perfusion. This explains why the upper zones are primarily affected whenever there is a disease or condition that is related to inhalation.

Some examples include:
– Tuberculosis
– Sarcoidosis
– Extrinsic allergic alveolitis

Lung Apices Overview
Smoke inhalation predominately affects the upper lobes as well. In fact, cigarette smoking can lead to centrilobular emphysema which presents with upper lung lobe predominance. Diseases that cause impaired mucociliary clearance also affect the upper lobes and make it more difficult to remove secretions from the airways. Even in conditions such as pneumonia, you may notice consolidation on a chest radiograph in the upper lobes. While we have provided some useful tidbits on this topic, when it comes to the medical definition of the lung apices, the important thing to remember is that this is the upper portion of the lungs.
