A quantitative study of the trachea in buffalo has been made. The trachea is found to be about 37.9 +/- 1.8 cm long. It weighs 219.8 +/- 34.08 gm and its capacity is 188.4 +/- 29.3 ml. Its length, weight and capacity appear to be significantly interrelated. The bronchus principalis dexter is found to be diverging at 23.5 degrees +/- 4.6 degrees angle, whereas the bronchus principalis sinister at 34.1 degrees +/- 8.4 degrees. Apart from the first tracheal ring, the trachea has the greatest outer transverse, outer vertical, inner transverse and inner vertical diameters from the fifth to the twentieth tracheal rings. Thereafter, these diameters gradually decrease upto the last tracheal ring, which has the shortest corresponding diameters. The vertical diameter is greater than the transverse diameter throughout the length of the trachea.
已对水牛的气管进行了定量研究。发现气管长约37.9 +/- 1.8厘米。其重量为219.8 +/- 34.08克，容量为188.4 +/- 29.3毫升。其长度、重量和容量似乎显著相关。发现右主支气管以23.5度 +/- 4.6度的角度分叉，而左主支气管以34.1度 +/- 8.4度的角度分叉。除了第一气管环外，气管从第五到第二十气管环具有最大的外侧横向、外侧纵向、内侧横向和内侧纵向直径。此后，这些直径逐渐减小直至最后一个气管环，其相应直径最短。在气管的整个长度上，纵向直径大于横向直径。
