title: The individualities of bronchioles of the upper and middle lobes in the lung of guinea pig.
abstract: The bronchiole variation found in Guinea pigs is important for our understanding of the individualities of the upper lobe and middle lobe bronchioles. The upper lobe bronchiole of the Guinea pig can be divided into three sorts, namely, the well developed, ill developed and completely absent ones. Generally the right lung as the upper lobe bronchiole, while the left lung lacks the upper lobe bronchiole in many cases.
