A study was conducted on the lungs of an adult wild sow collected soon after its death. The lungs were bluish pink in colour with distinct lobulations. Each lung was covered by pulmonary pleura and presented an apex, base, two surfaces and three borders. The right lung was larger than the left lung. It contained four lobes namely- cranial, middle, caudal and accessory lobes. The left lung presented a divided cranial lobe and a caudal lobe. A small tracheal bronchus originated from the trachea and entered the undivided cranial lobe of the right lung. Apart from the apical bronchus, the right lung presented middle, accessory and caudal lobar bronchi, ventilating corresponding lobes. The cranial and caudal lobar bronchi entered the cranial and caudal lobes of the left lung respectively. It was concluded that the gross anatomical features of the lungs of wild sow were similar to those of domestic pig.
