听力下降有脂肪吗:中级听力：脂肪储存的来龙去脉

When you eat a fatty food, it moves through thestomach andon to the intestines.
当你食用富含高脂肪的食物时，脂肪通过胃流入肠道。

In the intestines, a number of processes occur totransfer fat from the foodto special fat cells in yourbody.

在肠道中，脂肪经过一系列的消化流程从食物转化为体内的特殊脂肪细胞。

First, the gall bladder produces bile that breaks thefood's fat droplets into smaller droplets.

首先，胆囊分泌胆汁分解食物脂肪滴，使其更小。

Next,the pancreas secretes enzymes that attack the fat droplets and break them down into twoparts:fatty acids and glycerol.

然后，胰腺分泌胰腺酶作用于脂肪滴，将其分解为两个部分：脂肪酸和甘油。

This happens because fat droplets are too big to pass through cell membranes.

这是因为脂肪滴过大，无法穿过细胞膜。

The broken downfat is absorbed by the cells lining the intestine, where it is reassembled intofat molecules andeventually shuttled into the bloodstream with the help of lipoproteinparticles.

分解的脂肪被肠粘膜细胞吸收，重组成脂肪细胞，最后负载在脂蛋白颗粒上进入血液循环。

For the most part fat is stored in the fat cells that compose fatty tissue.

大部分的脂肪储存在脂肪细胞内，形成脂肪组织。

Think of a fat cell as a tinyplastic bag filled with a drop of fat.

脂肪细胞好比一个容纳脂肪滴的塑料袋。

Interestingly, fat cells do not multiply.

有趣的是，脂肪细胞并不会变多。
