The Bronchial Tree and Lobular Division of the Crab-Eating Monkey (Macaca fascicularis) Lung

Abstract

The lungs of 70 crab-eating monkeys were examined. The crab-eating monkey has the dorsal, lateral, ventral and medial bronchiole systems on both sides. According to the bronchial ramification, the right lung consists of the upper, middle, lower, and accessory lobes, whereas the left lung consists of a middle lobe which is bilobed and a lower lobe. These findings were based on the comparative anatomy of the bronchial tree and blood vessels of the mammalian lung.
