當你食用富含高脂肪的食物時，脂肪通過胃流入腸道。
In the intestines, a number of processes occur totransfer fat from the foodto special fat cells in yourbody.
在腸道中，脂肪經過一系列的消化流程從食物轉化為體內的特殊脂肪細胞。
First, the gall bladder produces bile that breaks thefood's fat droplets into smaller droplets.
首先，膽囊分泌膽汁分解食物脂肪滴，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，將其分解為兩個部分：脂肪酸和甘油。
This happens because fat droplets are too big to pass through cell membranes.
這是因為脂肪滴過大，無法穿過細胞膜。
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.
分解的脂肪被腸粘膜細胞吸收，重組成脂肪細胞，最后負載在脂蛋白顆粒上進入血液循環(huán)。
For the most part fat is stored in the fat cells that compose fatty tissue.
大部分的脂肪儲存在脂肪細胞內，形成脂肪組織。
Think of a fat cell as a tinyplastic bag filled with a drop of fat.
脂肪細胞好比一個容納脂肪滴的塑料袋。
Interestingly, fat cells do not multiply.
有趣的是，脂肪細胞并不會變多。
The body contains a finitenumber of fat cells that expand as they absorb fat.
