Abstract
The bronchial ramification in one specimen of gorilla lung was examined from the viewpoint of comparative anatomy, on the basis of the fundamental structure of bronchial ramification in the mammalian lung (Nakakuki, 1975, 1980). The right lung of the gorilla consists of the upper, middle, lower, and accessory lobes. The right lung has the dorsal, lateral, and ventral bronchiole systems, but the medial bronchiole system is lacking. The upper lobe is formed by the first branch of the dorsal bronchiole system. The middle lobe is formed by the first branch of the lateral bronchiole system. The accessory lobe is formed by the first branch of the ventral bronchiole system. The remaining bronchioles constitute the lower lobe. The left lung consists of the middle and lower lobes; the upper and accessory lobes are lacking. The left lung has the dorsal and lateral bronchiole systems, but the ventral and medial bronchiole systems are lacking. The middle lobe is formed by the first branch of the lateral bronchiole system. The remaining bronchioles constitute the lower lobe. The bronchial ramifications of the gorilla lung are rather similar to those of the human lung.
