We also talked about how epithelial cells are polar, having both apical and basal sides, and are selectively permeable, and lastly we took a brief look at how our glandular epithelial tissue forms both out endocrine and exocrine glands.

还讨论了上皮细胞是如何极性的，具有顶端和基底两侧，并且具有选择性渗透性，最简要了解了的上皮组织如何形内分泌和外分泌。

Alright, as a quick recap, your pancreas produces both hormones for the endocrine system and digestive enzymes for the exocrine system.

好！快速回顾：产生内分泌系统所需的2种激素岛素和高血糖素，以及外分泌系统所需的消化酶。

Some examples of exocrine secretions would be sweat, saliva, mucus, stomach acid, and milk, if you're lactating.

外分泌分泌物的一些例子是汗液，唾液，粘液，胃酸和牛奶（如果你在哺乳期的话）。

These exocrine glands produce a fluid called saliva, which is released, from the parotid gland, submandibular gland and sublingual gland on each side of the mouth.

这些外分泌产生一种称为唾液的液体，唾液从嘴两侧的腮，颌和舌中释放出来。

Exocrine glands are those which release their cellular secretions through a duct which empties to the outside or into the lumen of an organ.

外分泌是指通过导管将细胞分泌物排出体外或排入器官腔内的体。
