中文摘要:
      运用组织学和组织化学方法对栉江Zhao系统的结构和功能进行了研究。栉江Zhao消化管的粘膜上皮由纤毛柱状细胞和杯状细胞组成,唇瓣、中肠和上行肠的上皮层还有嗜酸性粒分泌细胞,消化盲囊的腺上皮由分泌细胞和消化(吸收)细胞组成。皮下结缔组织中富含血腔隙、结缔组织和血腔隙中有“颗粒细胞”。食道、胃、中肠、晶杆囊及消化盲囊能分泌消化酶,对食物进行消化和吸收;结缔组织,“颗粒细胞”也参与了食物的消化吸收。唇瓣、食道、晶杆囊和中肠的上皮细胞及结组织中的“颗粒细胞”内含铁、结缔组织中含钙。
英文摘要:
      The structure and function of digestive system of Pinna ( Atriina ) pectinata Linnaeus were studied using histological and histochemical methods. The epithelium of the digest ive tract is composed of columnar ciliated cells, goblet cells ( mocous cell) , and eosinphilic cell only in the epithelium of labial palp, mid-gut and ascending limb intestine. The epithelium of digestive diverticula consist s of secretory cells and digestive ( absorptive) cells. Many blood spaces present in the subcutaneous connective tissue, and / granular cells 0 exist in the connective tissues and blood spaces. The epithelium of esophagus, stomach, mid-gut , style sac and digestive diverticula can produce the digestive enzymes which involved in the digestion and absorption of food particles, and the connective tissues and / granular cell 0 also participate in the digestion and absorption of food. Ferric ion is present in the epithelium of labial palp, esophagus, mid-gut and style sac, and / granular cell 0in the connective tissues. Calcium exists in the connective tissue.
