1
Hey dude. My name’s Gilbert.
2
Gilbert The Grape.
3
Yeah the name was my dad’s idea… Anyway, today I’m going on an epic journey…through the human body!
4
So, wanna watch?
5
The trip starts as the human heads to the office lunch room, opens his lunchbox, and finds me in there.
6
What else has he got here?
7
A turkey sandwich, some yogurt, hmm!
8
I see he’s taken a bite of his sandwich.
9
Oh! Now it’s my turn!
10
He’s popped me into his mouth – it’s go time!
11
Gotta be honest, it’s pretty wet and warm in here.
12
The mouth is the gateway to the digestive system.
13
That system is designed specifically to transform food into useful nutrients that keep you energized and help your cells grow and repair.
14
So, once you grab the first bite of whatever you’re eating, you turn on the digestion machine.
15
As you chew, food is broken up into pieces to make the process easier.
16
Saliva comes in handy as it mixes with food and breaks it down even more.
17
That way, your stomach doesn’t have to digest whole chunks of food.
18
By the way, here’s a fun fact – the amount of saliva you produce in a year could fill 2 medium-sized bathtubs!
19
Almost a pool full of drool!
20
It’s really raining spit in here, ew!
21
Whoa, I better watch out for these teeth!
22
Wouldn’t wanna end up like Turkey Boy over there.
23
It’s hard since this guy’s using his tongue to roll food around his mouth and toward his teeth.
24
I don’t really feel like becoming jam today, so I’m just gonna bypass all this chewing!
25
Down the chute we go!
26
Weee!!! We’re now heading into the throat – they also call it the pharynx.
27
Uh-oh, fork in the road.
28
Which way do I go?
29
Eenie meenie miney moe –looks like this way we must go.
30
Hang on, I think I took a wrong turn.
31
Why is everything shaking?
32
Aw, poor human is coughing like crazy – someone give him a nice slap on the back.
33
There we go, coming back up!
34
Sorry, dude!
35
Phew, that was close!
36
Almost ended up in his lungs – that wouldn’t be good.
37
Alright, I’m back on the road, so let’s give it another try.
38
I’ve CORRECTLY turned into the swallowing tube that goes by the sophisticated name of esophagus.
39
I like to call it the “food chute” but it’s a lot less spacey than I imagined!
40
I’m getting kinda squooshed in here.
41
Uh oh, how do I keep going down?
42
Ah, I see. The muscles in the walls of this guy’s esophagus are squeezing behind me and relaxing in front of me.
43
This is a process called peristalsis, and it’s what moves me through your digestive system.
44
A couple seconds later, and we’ve now reached the end of the tunnel.
45
There’s a muscle here that opens up to let food into the stomach and keeps it from coming back out into the esophagus.
46
It’s kinda like the TSA in a way.
47
I’m just a tourist here, sir, please let me in.
48
Yay! I’ve passed through the valve and into the stomach.
49
It reminds me of a sac and … let me try those walls.
50
Wow, that’s a strong one – it’s all muscle.
51
I’m not surprised, actually.
52
The stomach holds, mixes, and grinds the food up into mush, so it has to be pretty strong.
53
Quite honestly, this doesn’t look too … oh my, what’s that?
54
That burns like crazy!
55
Ooh, ooh, hot!
56
I gotta get out of this stomach acid or else I’ll turn into liquid or paste like Turkey Sandwich over there!
57
That’s okay, I’ve come prepared!
58
I brought this handy-dandy little device that’ll incase me in a protective bubble.
59
Your food usually doesn’t have this, but I got…connections.
60
It’s classified.
61
I just have to push this button...
62
There, now I can keep talking to you the whole way instead of turning into grape jelly.
63
Next stop – the small intestine!
64
This long coiled snaky organ is made up of 3 sections.
65
When I say long, I mean it – if you spread it out (which I don’t recommend doing because you need it to be coiled…and inside of you…), you’d get a tube that’s over 20 feet in length!
66
Yep, that’s as long as a giraffe is tall…all stuffed into your insides!
67
I must say, it’s pretty warm in here.
68
Almost feels like a tropical resort, except I’m in an ocean of … bile!
69
Oh yeah, I’m protected in my little bubble, no worries!
70
Bile is crucial to digest fat and take all the waste out of your blood, so be thankful your liver produces it.
71
Your pancreas also helps the process with some good enzymes.
72
And that thing over there that looks like a pear – that’s the gallbladder.
73
It’s located under the liver and keeps bile in it until the right moment comes.
74
Man, this thing really is coiled, huh?
75
I’m getting kinda dizzy from the twists and turns.
76
But no going back now – these contracting intestinal walls keep pushing me forward.
77
Looks like I’m already in the final section of the small intestine and on to the next leg of my journey – the large intestine!
78
Also known as the colon, it’s a muscular tube that’s 5 to 6 feet long.
79
Hold the phone.
80
Shh. Do you hear that?
81
I’m not alone.
82
I’m surrounded.
83
They’re coming in closer.
84
It’s…It’s…bacteria!
85
There’s tons of them in here!
86
Uh-oh, is this person sick with some intestinal parasite or something?
87
Nah, your intestines need good bacteria to help them break down food, vitamins, and nutrients so that your body can use them.
88
Sup, peeps?
89
Hey, what’s that little dangly thing over there at the entrance?
90
Ah, that must be the appendix.
91
It doesn’t do much besides house bacteria that might need to be released into the gut.
92
It’s also got some tissues that are useful for your immune system.
93
But it’s mostly a useless little thing, so people can still live without it.
94
Hey, if your appendix gets inflamed, a doctor will cut it out of you!
95
Really! Looks like this guy still has his.
96
Good for you!
97
Anyway, we’re now in the large intestine, and I’m glad it’s a little roomier in here.
98
Had I not grabbed my fancy top-secret protective bubble, I’d be talking to you now as a liquidy yellowish mush of waste.
99
As these muscle contractions push me through the colon, I’d have all the water sucked out of me.
100
My final form: stool.
101
Yep, poo, do-do, #2, feces, whatever you like to call it, it’s formed in the large intestine.
102
Still loads of bacteria all over the place.
103
They’re really hard at work, eh?
104
Well, there can’t be too little or too many – otherwise you’d have digestive problems like food intolerances.
105
They also play a major role in your immunity, and that’s why you have trillions of them in your gut.
106
Keep up the good work, guys!
107
I'm on my way through the left colon.
108
When it gets too full of stool, it decides to dump it all into the rectum because it can't hold it all by itself.
109
It usually takes about 36 hours for what’s left of your food (not much now, just waste) to reach this point.
110
But I’ve been speeding through this journey because I’ve got some other grape stuff to do.
111
So let’s head to the rectum already.
112
Geronimo!!!
113
The rectum is a straight chamber that’s about 8 inches long.
114
It has special sensors, like this one or that one there, that let you know when there’s something you should get rid of.
115
They send a signal to the brain when stool or gas wanna make their exit.
116
That’s about the time when a thought pops up in your brain, “Oh, gotta go to the bathroom!” If the moment is right for you (that is, you find a toilet), the sphincters relax, and ta-da!
117
Your stool makes its exit.
118
Buh-bye, pizza from yesterday’s breakfast!
119
What? No one else here has cold pizza for breakfast?
120
Alright, then let me know down in the comments, what your typical breakfast looks like!
121
Anyway, when the moment isn’t exactly right to release stool just yet, your sphincters contract.
122
Those rectum sensors help too so that the urge to release its contents disappears for a while.
123
You should be happy your rectum and sphincters are working hard to keep stuff in when the timing isn’t good.
124
Like when you’re driving to work, on a date, getting groceries, sleeping!
125
But when you just can’t resist the urge anymore, the external sphincter, also called the anus, gives you a couple more minutes or however long you need until you make it to the bathroom!
126
Well, not sure if the human is ready, but I’d really like to go now.
127
Maybe I can hotwire these sensors to make my great escape.
128
Oh yeah, this guy is at work, isn’t he?
129
Um, this is gonna be awkward…Of course, normal food doesn't leave your body in such a graceful manner.
130
You wouldn't even recognize what was what!
131
But as for me, Gilbert The Grape, I still have important things to do, so hey, bub, let’s hit the john!
132
I’m outta here!
133
Byeee! Well that was different.
134
Hey, if you learned something new today, then give the video a like and share it with a friend!
135
And here are some other cool videos I think you'll enjoy.

シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
