The bronchial tree and pulmonary artery of the tamandua (Tamandua tetradactyla) lung--an important example supporting the fundamental scheme for the bronchial ramification of the mammalian lung.

The lungs of a tamandua were examined on the basis of the scheme proposed for the fundamental structure of the bronchial ramification of the mammalian lung. The right lung has the dorsal, lateral, medial and ventral bronchiole systems, whereas the left lung has the dorsal, lateral and medial bronchiole systems. Three kinds of upper lobe bronchioles and a middle lobe bronchiole are present on both sides.

Bronchial ramification and lobular division of the lung of the Japanese badger (Meles meles anakuma).

The right lung of the Japanese badger (Meles meles anakuma) consists of the cranial, middle, caudal and accessory lobes. The left lung consists of the middle and caudal lobes. The Japanese badger has four bronchiole systems, dorsal, lateral, ventral and medial, on each side.

Bronchial tree, lobular division and blood vessels of the nutria (Myocastor coypu) lung--evidence for the individual nature of the bronchioles in the upper and middle lobes.

Four nutria (Myocastor coypu) lungs were examined. The right lung consists of the upper, middle, lower and accessory lobes, whereas the left lung consists of the upper, middle and lower lobes. These lobes are completely separated, and the upper and middle lobes are particularly well developed on either side.

The bronchial tree and lobular division of the lung in the striped dolphin (Stenella coeruleo-albus).

According to the fundamental structure of the bronchial ramification of the mammalian lung proposed by the present author [5, 6], the lung of the striped dolphin (Stenella coeruleo-albus) consists of the cranial and caudal lobes on either side. Both lobes are united to form a single one. The middle and accessory lobe bronchioles are lacking on either side.

Bronchial tree, lobular division and blood vessels of the pig lung.

The pig lung has the dorsal, ventral, medial and lateral bronchiole systems on either side. In addition, a tracheal bronchiole (bronchus) arises from the right side of the trachea. According to the bronchial ramification, the right lung consists of the cranial, middle, caudal and accessory lobes, while the left lung consists of the bilobed middle and caudal lobes.
