Definition
The middle lobe of the right lung is an anatomical division of the right lung present in most domestic animals, with the exception of the horse. It is ventilated by the right middle lobar bronchus, which branches from the right main bronchus.
The middle lobe begins at the cranial interlobar fissure that separates it from the right cranial lobe and ends in a ventral tip shaped like a pyramid. The medial surface of this lobe is deeply excavated by the heart, contributing to the cardiac impression. Together with the right cranial lobe, it forms the cardiac notch of the right lung.
