Today my giant friend here is lending us his mouth so I can talk to you about teeth

今天，我的這位大朋友把他的嘴借給我們，讓我們可以來談談牙齒。

To start, human adults have 32 of those...what's going on here?

首先，成年人有32顆……發生了什麼？

Well, it looks and smells like my friend here started drinking and on an empty stomach it seems.

呃……我的朋友看起來和聞起來都似乎是在空腹的情況下開始喝酒。

I guess this is a good time to talk to you about what happens inside your body when you're drunk.

我想這是一個好時機來和你談談當你喝醉時身體發生了什麼。

I'll do the teeth thing at another time.

我下次再來談牙齒的事。

While a small amount of alcohol is absorbed in the small blood vessels in your mouth and tongue, the majority is absorbed into your bloodstream

雖然少量酒精會被口腔和舌頭的小血管吸收，但大部分會被吸收到血液中。

While in your digestive system, the stomach here absorbs about 20 percent.

在你的消化系統中，胃吸收了大約20%。

If my friend had eaten something first, the alcohol would be diluted and take longer to absorb.

如果我的朋友有先吃點東西，酒精就會被稀釋，便需要更長的時間來吸收。

And since it would have stayed here longer, some would be broken down by stomach enzymes.

而且由於它會在這裡停留更久一些，一些酒精會被胃酶分解。

But since they didn't, it's going to move into these small intestines quickly, where the rest will be absorbed.

但由於它們沒有被分解，所以會迅速進入小腸吸收剩餘部分。

Here in the bloodstream, the alcohol makes your blood vessels widen, which can cause blushing, a temporary feeling of warmth, and a rise in blood pressure.

在血液中，酒精會使你的血管擴張，從而導致臉紅、短暫的體溫以及血壓上升。

It moves throughout the body pretty fast, reaching the brain in just 5 to 10 minutes.

它在整個身體內的移動速度相當快，在短短5至10分鐘內就能到達大腦。

Uh... the precious and extremely confusing brain! 

呃，寶貴而又極度混亂的大腦！

Here is where things really start to happen.

這裡是一切的開端。

Alcohol interferes with the brain's communication pathways by blocking chemical signals between brain cells called neurons.

酒精阻斷一種腦細胞，也就是神經元，之間的化學信號，使大腦的通信途徑受到影響。

This makes it harder for the brain to control your body, leading to slurred speech, slowed reflexes, and imbalance.

這使得大腦更難控制你的身體，導致說話含糊不清、反應遲鈍和身體不平衡。

It can also make it harder to think clearly and affect your short-term memory as you continue to drink, which it seems is the case for my friend here.

它還會使人很難保持清醒，當你繼續喝酒時，就會影響你的短期記憶，我的朋友似乎就是這種情況。

Your blood alcohol content or BAC, goes up.

你血液中的酒精含量，也就是Bac上升。

As this happens, these effects on your brain get worse.

當這個情況發生時，就會對大腦產生更糟糕的影響。

Eventually your brain functions will get severely impaired and you'll be risk of passing out, going into a coma, or even death.

最終你的大腦功能將受到嚴重損害，你將會有暈倒、昏迷、甚至死亡的風險。

Thankfully, my friend hasn't been drinking that much, and their liver is hard at work, breaking down the alcohol.

幸好，我的朋友沒有喝那麼多，他的肝臟正在努力工作來分解酒精。

The liver is one of the organs that filter your blood.

肝臟是過濾血液的器官之一。

Here with the help of enzymes, alcohol goes from its original form, ethanol, to a toxic carcinogen, acetaldehyde, to acetate, and finally to carbon dioxide and water.

在酶的幫助下，酒精從原始形式的乙醇變成了有毒的致癌物乙醛，然後是醋酸，最後變成二氧化碳和水。

While acetaldehyde is short-lived, it can cause significant damage especially to the liver.

雖然乙醛的壽命很短，但它可以造成重大損害，特別是對肝臟。

Since this is where about 90 percent of the alcohol is broken down.

因為大約90%的酒精是在肝臟中分解的。

Nearly all the rest is processed by the kidneys , which also filter your blood and remove harmful substances like alcohol through urine.

幾乎剩下的所有部分都由腎臟處理，而腎臟也會過濾你的血液並藉由尿液排出酒精等有害物質。

Kidneys also regulate the amount of water in your body by monitoring the amount of particles in your blood, compared to fluid, since alcohol is a fluid.

腎臟能夠監測你的血液粒子的數量，並將其和血液（因為酒精是一種液體）作比較，來調節你體內的水含量。

This is why you pee more when you drink.

這就是為什麼你喝酒時尿得更多。

But alcohol can make your kidneys release more water than they should.

但酒精會使你的腎臟排出更多的水份。

While messing with your brain's communication system, the alcohol prevents the brain from releasing a hormone called vasopressin, or anti-diuretic hormone.

在擾亂你的大腦通信系統的同時，酒精也會阻止你的大腦釋放一種叫做血管加壓素的激素，或稱抗利尿激素。

This hormone tells your kidneys to hold on to water.

這種激素會告訴你的腎臟要把水分留住。

So without it, your kidneys are just making you pee constantly.

所以如果沒有它，你的腎臟就會讓你不斷想排尿。

So, let's get out of here before that happens.

所以，我們趕快在那個發生前離開吧。

I really don't want to exit the body through that end.

我真的不希望通過那個來離開身體。

Here we are, back to where it all began.

我們到了，又回到了一切開始的地方。

As I was saying, excess urination can lead to dehydration and common hangover symptoms like headaches and nausea.

因為我說過，排尿過多會導致脫水和常見的宿醉症狀，如頭痛和噁心。

Once your BAC is back to normal, which it seems like is the case for my friend here, and that means ... oh no.

一旦你酒醒了，這似乎是我的朋友的情況，就會發現……不！

Well, I definitely need my data scrubbed.

好吧，我需要刷新我的數據。

So if you're of age, tell me how many drinks can you handle, and if you're not, let us know what other 360 VR videos you want us to make .

如果你是成年人，告訴我可以你的酒量是多少，如果你不是，讓我們知道你希望我們製作什麼樣的VR影片。
