abstract
In a light microscopic study, spleen, lung and kidney of Pygmy hog (Porcula salvania) were observed. The spleen was covered by a thick layer of capsule. The parenchymatous tissue of spleen composed of red pulp and white pulp. In lung bronchiole, lymphoid aggregation, smooth muscle and mucosal fold of bronchiole were observed. The kidney of Pygmy hog was surrounded by a capsule and it was composed of cortex and medulla. In cortex, glomerulus, collecting tubule, and ascending and descending loop of Henle were observed. The collecting tubules were lined by simple cuboidal epithelium. The diameter of ascending loop was larger compared to the diameter of descending loop of Henle.
