RML

Acronym for the right middle lobe (of the lung).</P> The right lung has three lobes: the right lower lobe (RLL), the right middle lobe (RML), and the right upper lobe (RUL).</P> The left lung has but two lobes: the left upper lobe (LUL) and the left lower lobe (LLL).</P> The reason why the right lung has three lobes whereas the left lung has only two is not known but a convenient (albeit teleological) way to think about it is that the lack of a lobe on the left leaves room for the heart on that side.</P> RML stands for a number of other, medically less relevant things such as remote microwave link and, carved on a tree, 'Remember my love.'
