唾液是一种平淡无奇的液体,人们很少认真对待它——直到你失去了它。如果你的唾液腺不再正常而勤劳地每天分泌3到5升唾液,你就会珍惜这种奇妙的物质了——它的作用不仅是让食物变成糊状和易于消化而已。唾液成分复杂科学家已经发现,唾液比水要复杂得多。它含有多种蛋白质,帮助控制我们口腔里的大量菌群。它充满某些使唾液变得黏稠的物质,防止牙齿受腐蚀并促进伤口愈合。它携带大量激素和其他化学物质,能够揭示一个人是否吸烟或是否感到紧张。
Saliva is a bland fluid, and it is seldom taken seriously - until you lose it. If your salivary glands are no longer working properly and industrially excrete 3 to 5 liters of saliva, you will treasure this marvelous substance - its role is not only to make the food mush and easy to digest. Complex saliva ingredients Scientists have found that saliva is much more complex than water. It contains a variety of proteins that help control the mass of bacteria in our mouth. It is filled with some substances that make saliva sticky, preventing the teeth from corroding and promoting wound healing. It carries large amounts of hormones and other chemicals that reveal whether a person smokes or is nervous.
