Food’s travel in our body 食物在身体里

We eat food everyday.

我们每天都吃饭。

When food comes into our mouth, the salivary glands in our mouth moisten the food and break it down into pieces. our teeth grind them and until the pieces are small enough to swallow.  Then our tongue pushes them to the back of our mouth for swallowing.

当食物进入我们的嘴巴，我们嘴里的唾液腺将其润湿成碎片；我们的牙齿把它咀嚼到足够小，小到可以被吞下；然后，我们的舌头把它抵到口腔的后部，就可以吞下去了。

Next, the food enters a tube called the esophagus. Gravity and muscles push food down to our stomach, where the strong acids turn our food into soupy liquid .  Later, our liquefied food passes into the small intestine that coils back and forth in our body.  During the following six hours, special liquids digest the food even further and our body pull nutrients here.

然后，食物到达一个管道，即食管。在重力作用和肌肉的推动下，食物进入我们的胃。胃里丰富的胃酸将食物转化成流体。然后，流体食物进入我们的小肠，小肠前后蠕动。在接下来的六个小时里，小肠里的特殊液体进一步消化食物。我们的身体在这里吸收营养。

How about the things our body doesn’t need?  They pass into the large intestine.  Over the 10-36 hours, water and minerals are absorbed here.  After the most of the liquid is removed, the leftover material passes out of our body.  That is the solid waste.

那没有被吸收的物质怎么样了呢？它们通过大肠，在10-36小时里，水和矿物质在这里被吸收。当大部分的水排掉之后，剩余物质便会被排出身体，那就是大便。

Oh, the food finishes its travel.

呀，食物就这样完成了在我们身体里的旅行。❤️
