Tear production is a complex multi-step process that can be arbitrarily divided into three stages: «primary» secretion by the acinar cells of the main lacrimal glands, formation of «secondary» lacrimal fluid in the ducts of the main lacrimal glands, and «tertiary» modification of the tear composition in the conjunctival sac. This article highlights mechanisms of water and electrolytes secretion in the process of tear fluid production and describes the particularities of distribution of the membrane transport proteins in the lacrimal gland and the ocular surface.
泪液分泌是一个复杂的多步骤过程，可大致分为三个阶段：主泪腺腺泡细胞的“初级”分泌、主泪腺导管中“次级”泪液的形成以及结膜囊中泪液成分的“三级”修饰。本文重点介绍泪液生成过程中水分和电解质分泌的机制，并描述泪腺和眼表中膜转运蛋白分布的特点。
