我为什么流口水?为什么呢?
Is your mouth Watering? Does your mouth water when you smell something tasty? That water is called saliva. Think about your favorite food. Is your mouth starting to water? Do you ever wake up with a wet pillow? Sometimes saliva leaks out when you are asleep. That is one way we drool. To drool is to leak saliva from our mouths. Sometimes people can drool when they are awake, too.
你在流口水吗?当你闻到好吃的东西时,你会流口水吗? 这种水叫做唾液。 想想你最喜欢的食物。 你开始流口水了吗? 你醒来时枕头湿过吗? 有时候,当你睡着的时候,唾液会流出来。 这是我们流口水的一种方式。流口水就是从嘴里漏出唾液。 有时人们在醒着的时候也会流口水。
Crunch and Slurp You use your teeth to chew your food into smaller pieces. This makes it easier for your body to break down the food when it reaches your stomach. Your mouth makes a lot of saliva when you chew your food. Saliva begins to break down the food even before you swallow it. Saliva is made up mostly of water. It also contains other things that help break down food
你用牙齿把食物嚼成小块。 这样当食物到达你的胃时,你的身体更容易分解食物。 当你咀嚼食物时,你的嘴巴会分泌很多唾液。 在你吞下食物之前,唾液就已经开始分解食物了。 唾液的主要成分是水。 它还含有其他有助于分解食物的物质
Busy mouths There are different body parts inside and around your mouth. They all help you digest, or break down, your food Teeth cut and crush your food. Body parts called glands make saliva. Food travels down to your stomach through a long tube connected to your throat. The little bumps on your tongue are called taste buds. They tell your brain what food tastes like. Your tongue moves the food around inside your mouth. Saliva also helps to keep your mouth wet. Imagine trying to talk or swallow with a very dry mouth. It would be almost impossible!
嘴的内部和周围有不同的身体部位。 它们都能帮助你消化或分解你的食物。 被称为腺体的身体部位产生唾液。 食物通过一根与喉咙相连的长管子进入你的胃。 舌头上的小突起叫做味蕾。 它们会告诉你的大脑食物的味道。 你的舌头在嘴里移动食物。 唾液也有助于保持口腔湿润。 想象一下,试图用非常干燥的嘴说话或吞咽。 这几乎是不可能的!
Chew and Swallow STEP 1: As soon as you take a bite of food, your saliva goes to work! STEP 2: Your glands send saliva into your mouth as you chomp down on food. The more you chomp, the more saliva is sent. STEP 3: Your tongue moves the food around your mouth. When it is chewed into a ball, the tongue pushes it to the back of your throat. STEP 4: Finally, you swallow. Saliva helps the ball of food slip down your throat easily.
咀嚼和吞咽第一步:只要你咬一口食物,你的唾液就开始工作了!第二步:当你咀嚼食物时,你的腺体会将唾液送入口腔。 你咀嚼得越多,分泌的唾液就越多。 第三步:舌头在嘴里移动食物。 当它被咀嚼成一团时,舌头会把它推到喉咙后面。 第四步:最后,吞咽。 唾液可以帮助食物团很容易地从喉咙里滑下去。
Drool Drool So why does your mouth water when you smell something delicious? When you smell food, your brain thinks you are about to eat. It sends instructions to the glands to prepare your mouth for the meal by filling it with saliva! You swallow your saliva when you are awake. You don't swallow saliva when you are asleep. Saliva builds up in your mouth. It can sometimes leak out as drool.
当你闻到美味的食物时,为什么你会流口水呢? 当你闻到食物的味道时,你的大脑会认为你要吃了。 它会向腺体发出指令,让你的嘴充满唾液,为吃饭做准备!当你醒着的时候,你会吞咽唾液。 你睡觉的时候不会吞口水。 唾液在你的嘴里积聚。 它有时会以流口水的形式泄漏出来。
