This pill houses a mini film crew, complete with lights and camera.

這顆藥丸裡有一個小型攝製組，配有燈光和攝影機。

It will take pictures three times a second and transmit them to screens here in the Science Museum via sensors on my body.

它將每秒拍攝三張照片，並通過我身上的傳感器將照片傳送到科學博物館的螢幕上。

Food can take up to three days to travel through the gut, but last night I drank four litres of laxative, so I'm expecting my camera to travel rather more quickly than that.

食物通過腸道可能需要長達三天的時間，但昨晚我喝了四升瀉藥，所以我期待我的相機能比這更快地通過腸道。

Anytime you swallow food, the esophagus will be able to tell that there's a force on its muscles to try and push it further down.

每次吞嚥食物時，食道都會感覺到其肌肉受到了某種力量，試圖將食物進一步向下推。

So this black hole here, soon you'll see the capsule passing into the stomach.

所以，這個黑洞很快就會看到膠囊進入胃裡。

Down here, it's a cavernous alien landscape.

在這下面，是一個洞穴般的外星景觀。

And you can see some white blobs of porridge I ate for breakfast.

你還可以看到我早餐吃的白粥。

I'm going to test the powers of my digestive system by feeding it a substantial meal with a big meal of steak and chips inside me.

我要給我的消化系統喂上一頓豐盛的大餐，讓它在我體內大吃一頓牛排和薯條，以此來測試我消化系統的能力。

The average human stomach can expand from the size of a small apple when it's empty to about two litres when full.

普通人的胃可以從空腹時的小蘋果大小膨脹到飽腹時的大約兩升。

The camera has now been travelling inside me for over four hours and embarked on the longest part of its journey.

現在，相機已經在我體內旅行了四個多小時，開始了它最漫長的一段旅程。

The tight folds on the wall of the small intestine are mixing and churning my mushed-up food in a corkscrew motion.

小腸壁上緊密的褶皺正在以開塞露的方式混合和攪動我的食物。

Digestive enzymes from the pancreas and gallbladder flood the area.

來自胰腺和膽囊的消化酶充斥著該區域。

These enzymes induce chemical reactions which break the food down into nutrients that my body can readily absorb.

這些酶會引起化學反應，將食物分解成人體易於吸收的營養物質。

So on the folds here, on the folds of the small bowel, you can see the finger-like projections of the small bowel lining, which are called villi, and what they do is to increase the surface area of the small bowel hugely.

是以，在這裡的褶皺上，在小腸的褶皺上，你可以看到小腸內膜手指狀的突起，這就是絨毛，它們的作用是增加小腸的表面積。

What sort of surface area are you talking about?

About a tennis court size, if you strip it all out, so it's really huge.

如果全部剝離，大約有一個網球場那麼大。

There's a huge amount of work that goes on in there.

And all this work requires a healthy blood supply.

而所有這些工作都需要健康的血液供應。

As I'm lying here digesting my steak and chips, a third of my body's blood is being diverted away from my extremities and towards the action in my guts.

當我躺在這裡消化我的牛排和薯條時，我體內三分之一的血液正從我的四肢流向我的內臟。

And as this blood rushes through the vessels in the wall of my small intestine, it's picking up digested nutrients and transporting them all over my body.

當這些血液在小腸壁的血管中奔流時，就會吸收消化後的營養物質，並將它們輸送到全身各處。

It's been almost nine hours since I swallowed the camera and began life as a museum exhibit.

自從我吞下相機，開始了博物館展品的生活以來，已經過去了將近九個小時。

We're at the outer reaches of this alien world.

The camera has travelled over five metres through my guts.

相機在我的內臟中穿行了五米多遠。

You can see that the lining of the colon is very much flatter and whiter than the small bowel, and you can see the little blood vessels running through very, very clearly in colon.

你可以看到結腸的內壁比小腸平整得多，也白得多，而且你可以非常清楚地看到結腸中貫穿的小血管。

Through the flatter, wider surfaces of the colon, water is being drawn out from what we have some slightly more formed material in there.

通過結腸更平坦、更寬闊的表面，水從結腸中一些稍微成型的物質中被吸出。

 That's Mark's polite way of saying that what we're looking at is faeces.

馬克禮貌地表示，我們看到的是糞便。
