Which abbreviation is associated with the right lower lobe of the lung?

The abbreviation that represents the right lower lobe of the lung is RLL. In anatomical terminology, the lung is divided into lobes, and for the right lung, there are three lobes: the right upper lobe (RUL), the right middle lobe (RML), and the right lower lobe (RLL). Therefore, RLL specifically denotes the lower lobe of the right lung.

The choice of RML refers to the right middle lobe, while RLQ pertains to the right lower quadrant, a term more commonly associated with abdominal anatomy rather than the lungs. RLE signifies the right lower extremity, which again is unrelated to lung anatomy. Each of these terms serves its specific context, but only RLL accurately describes the right lower lobe of the lung.
