Most of insects usually don not have the hemcoyte for transporting oxygen, the respiratory of insect is chiefly accomplished by the tracheal system that spreads all over the whole body. Outside oxygen enters the tracheal system through spiracles arranged in two sides of body and is transported through trachea and tracheoles to meet directly the needs of tissues.

一般认为大多数昆虫体内没有运输氧的血细胞存在，昆虫呼吸主要是靠遍布全身的气管系统来完成，O2靠扩散作用由分布于昆虫身体两侧的气门处进入，经气管、微气管的运输而直接给组织供氧。
