摘　　要：甲壳动物渗透压除了由鳃上皮执行调节外,还与触角腺、小颚腺等排泄器官有关。由于其迷路和原肾管由具有典型离子转运结构的细胞组成,因而这些器官不仅具有排泄代谢废物的功能,还在渗透压调节、酸碱平衡等方面具有重要的生理作用。The excretion organs in crustacean are antennary gland and maxillary gland. They consist of coelomosac, labyrinth and nephiridial canal. There is a single layer of podocytes in the coelomosac, coated with basal lamina. It plays a role to filtrate out preliminary urine and reabsorb the proteins, amino acids and glycoses from the blood. The later two structures are canals which consist of cells with typical structures in ion-transportation. Thus, the antennary gland and maxillary gland play roles not only in excretion, but also in osmoregulation, and acid-alkali homeostasis.
