  • Beneath your ribs, you'll find, among other things, the pancreas, an organ that works a lot like a personal health coach.

    在你的肋骨之下,你會在其它東西之間發現胰臟,一個像是私人健康教練般運作的器官。

  • This organ controls your sugar levels and produces a special juice that releases the nutrients from your food to help keep you in the best possible shape.

    這個器官會控制你的血糖值並製造一種特別的液體,用來釋放你所吃食物的營養,以幫助你保持最佳狀態。

  • The pancreas sits just behind your stomachan appropriate home, as one of its jobs is to break down the food you eat.

    胰臟正位在你的胃後面,一個適當的家,因為它的其中一項工作就是分解你所吃進的食物。

  • It aids digestion by producing a special tonic made of water, sodium bicarbonate, and digestive enzymes.

    胰臟透過製造一種由水製成的特別液體、小蘇打及消化酶來協助消化。

  • Sodium bicarbonate neutralizes the stomach's natural acidity so these digestive enzymes can perform their jobs.

    小蘇打會中和胃臟中天然的酸,讓這些消化酶可以發揮作用。

  • Lipase breaks down fatty substances, protease splits up proteins, and amylase divides carbohydrates to create energy-rich sugars.

    脂肪酶會分解脂肪、蛋白酶會分解蛋白質,而澱粉酶則會分解碳水化合物以製造富含能量的糖分。

  • Most of those nutrients then get absorbed into the blood stream and go on to enrich the body.

    這些養分大多隨後會被人體吸收進入血液中並持續滋養身體。

  • While all this is happening, the pancreas works on another critical task: controlling the amount of sugar in your blood.

    當這些都在發生時,胰臟也正執行另一項重要任務,也就是控制血液中的糖分含量。

  • It achieves this with the hormones insulin and glucagon, which are produced in special cells called the Islets of Langerhans.

    胰臟依靠稱為胰島素和升糖素的荷爾蒙達成這項任務,而這些荷爾蒙都是在稱為胰島的特別細胞中所製造。

  • Having too much or too little sugar can be life threatening, so the pancreas must stay on constant alert.

    擁有過多或是過少的糖分都可能有生命威脅,因此胰臟必須隨時保持警覺。

  • After a big meal, the blood often becomes flushed with sugar.

    在一頓大餐後,血液中通常會充滿糖分。

  • To bring us back to normal, the pancreas releases insulin,

    為了讓我們回到正常狀態,胰臟會釋放胰島素,

  • which makes the excess sugar move into cells where it's either used as an energy source or stored for later.

    胰島素則會將多餘的糖分移到細胞中,當作能量來源使用或是儲存以備日後之需。

  • Insulin also tells the liver to shut down sugar production.

    胰島素也會指揮肝臟停止製造糖分。

  • On the other hand, if blood sugar is low, the pancreas releases a hormone called glucagon that tells the body's cells and liver to release stored sugars back into the bloodstream.

    另一方面,如果血糖較低,胰臟會釋放稱為升糖素的荷爾蒙,它會進而通知身體細胞和肝臟將儲藏的糖分釋放回血液中。

  • The interplay between insulin and glucagon is what keeps our sugar levels balanced.

    正是胰島素和升糖素的交互作用讓我們血糖值得以保持平衡。

  • But a faulty pancreas can no longer coach us like this, meaning that this healthy balance is destroyed.

    但是一個有缺陷的胰臟就無法再像這樣指導我們,意味著這健康的平衡被破壞了。

  • If it's weakened by disease, the organ's ability to produce insulin may be reduced or even extinguished, which can trigger the condition known as diabetes.

    如果它是因疾病而變得衰弱,這個器官製造胰島素的能力可能會降低甚或消失,可能引發所為糖尿病的病狀。

  • Without regular insulin release, sugar steadily builds up in the blood, eventually hardening the blood vessels and causing heart attacks, kidney failure, and strokes.

    沒有了規律釋放的胰島素,糖分會慢慢累積在血液中,最終使得血管硬化並引發心臟病、腎衰竭和中風。

  • The same lack of insulin deprives cells of the energy-rich sugar they need to grow and function.

    缺乏胰島素一樣會剝奪細胞賴以成長和運作、富含能量的糖分。

  • People with diabetes also tend to have higher levels of glucagon, which makes even more sugar circulate.

    糖尿病患者的升糖素值一般也偏高,導致更多糖分在體內循環。

  • Without this internal health coach, our sugar levels would go haywire, and we wouldn't be able to digest important nutrients.

    少了這個體內的健康教練,我們的血糖值會大亂,讓我們將無法消化重要的營養素。

  • But, like any coach, it's not the pancreas' job alone to keep us healthy.

    但就像任何教練一樣,保持我們的健康不只是胰臟的工作。

  • It needs our conscious participation, too.

    它也需要我們有意識地參與。

Beneath your ribs, you'll find, among other things, the pancreas, an organ that works a lot like a personal health coach.

在你的肋骨之下,你會在其它東西之間發現胰臟,一個像是私人健康教練般運作的器官。
