Q & A

What is the purpose of the human digestive system?

The purpose of the human digestive system is to transform food into useful nutrients that keep you energized and help your cells grow and repair.

How does saliva aid in the digestion process?

Saliva mixes with food and breaks it down further, making it easier for the stomach to digest rather than having to process whole chunks of food.

What is a fun fact about the amount of saliva produced in a year?

The amount of saliva produced in a year could fill 2 medium-sized bathtubs.

What is the name of the tube that connects the throat to the stomach?

The tube that connects the throat to the stomach is called the esophagus, also referred to as the 'food chute' in the script.

What is the process called that moves food through the digestive system?

The process is called peristalsis, which involves the muscles in the walls of the digestive system squeezing behind the food and relaxing in front of it.

What is the function of the stomach in the digestive process?

The stomach holds, mixes, and grinds the food up into mush, utilizing its strong muscular walls.

What does the small intestine consist of and how long can it be if uncoiled?

The small intestine is made up of 3 sections and can be over 20 feet in length if uncoiled, which is as long as a giraffe is tall.

What is the role of bile in the digestive system?

Bile is crucial for digesting fat and removing waste from the blood, produced by the liver.

What is the function of the appendix?

The appendix houses bacteria that might need to be released into the gut and contains tissues useful for the immune system, but is generally considered to be of little use.

How does the large intestine, or colon, contribute to the formation of stool?

The large intestine absorbs water from the remaining indigestible food matter, transforming it into a liquidy, yellowish mush of waste, or stool.

What is the role of bacteria in the large intestine?

Bacteria in the large intestine help break down food, vitamins, and nutrients for the body to use, and they play a major role in immunity.

What is the process that signals the brain when it's time to have a bowel movement?

Special sensors in the rectum send a signal to the brain when stool or gas wants to make an exit, prompting the thought 'Oh, gotta go to the bathroom!'

🍇 Journey Through the Digestive System

Gilbert The Grape embarks on an educational adventure through the human digestive system, starting from being consumed in the mouth. He describes the process of chewing, the role of saliva, and the importance of the mouth as the entry point to the system. Gilbert humorously navigates the challenges of the mouth, including avoiding being crushed by teeth, and then moves into the throat, or pharynx, where he narrowly avoids entering the lungs. He correctly identifies the esophagus as the next stage of the journey, explaining the process of peristalsis that propels food through the digestive tract. Finally, Gilbert reaches the stomach, where he uses a protective device to avoid being dissolved by stomach acid, and prepares to continue his journey to the small intestine.

🌀 The Intestines: Bile, Bacteria, and Beyond

In the second part of his journey, Gilbert explores the small and large intestines, detailing the structure and function of these organs. He explains how the small intestine, a long coiled organ, is responsible for the absorption of nutrients with the help of bile from the liver and enzymes from the pancreas. Gilbert also describes the gallbladder's role in storing bile. Moving into the large intestine, or colon, he encounters beneficial bacteria essential for digestion and immunity. He humorously discusses the appendix as a mostly vestigial organ that houses bacteria. Gilbert then describes the process of stool formation and the role of the rectum and sphincters in controlling bowel movements. He concludes his journey by exiting the body, emphasizing the importance of the digestive system's role in health and the immune system.

Keywords

💡Digestive System

The digestive system is a series of organs responsible for breaking down food into nutrients that the body can use for energy, growth, and cell repair. In the video, the journey begins in the mouth, which is the entry point of the digestive system, and continues through various organs like the stomach and intestines, illustrating the process of digestion.

💡Saliva

Saliva is a fluid produced by salivary glands in the mouth that aids in the digestion of food by moistening it and beginning the breakdown process through enzymes. In the script, it's mentioned that saliva mixes with food to facilitate chewing and digestion, highlighting its importance in the initial stage of digestion.

💡Peristalsis

Peristalsis is the involuntary muscle contractions that move food through the digestive tract. The script describes peristalsis as the mechanism that propels the food item, represented by Gilbert The Grape, through the esophagus and other parts of the digestive system, emphasizing the role of muscle contractions in digestion.

💡Esophagus

The esophagus, referred to as the 'food chute' in the video, is a muscular tube that connects the mouth to the stomach, allowing the passage of food. The script uses the esophagus as a part of the journey to show how food travels from the mouth to the stomach through a series of muscle contractions.

💡Stomach Acid

Stomach acid is a corrosive fluid secreted in the stomach that helps break down food and kill bacteria. In the video, the character expresses concern about the stomach acid, indicating that it is a powerful substance capable of turning food into a digestible mush, which is crucial for further digestion.

💡Small Intestine

The small intestine is a long, coiled organ where most of the digestion and absorption of nutrients occurs. The script describes the small intestine as a 'long coiled snaky organ' and mentions its length, emphasizing its role in nutrient absorption and the continuation of the digestive process.

💡Bile

Bile is a fluid produced by the liver and stored in the gallbladder that helps in the digestion of fats. The video script mentions bile as crucial for digesting fat and cleaning waste from the blood, illustrating its importance in the digestive process.

💡Pancreas

The pancreas is an organ that secretes enzymes and hormones to aid in digestion and regulate blood sugar levels. In the script, the pancreas is mentioned as assisting in the digestion process by providing enzymes, showing its collaborative role with other organs in digestion.

💡Large Intestine

The large intestine, also known as the colon, is where water is absorbed, and the remaining indigestible food matter is formed into feces. The video describes the large intestine as a muscular tube that houses beneficial bacteria and is involved in the formation of stool.

💡Bacteria

Bacteria in the context of the video refers to the beneficial microorganisms in the gut that aid in digestion and contribute to immune function. The script personifies the bacteria, suggesting their essential role in breaking down food and supporting overall health.

💡Sphincter

A sphincter is a ring-like muscle that controls the opening of the digestive tract at various points, such as the anus. The video script discusses the role of the external sphincter in controlling the release of stool, highlighting the body's ability to regulate bowel movements.

Transcripts

Hey dude.

My name’s Gilbert.

Gilbert The Grape.

Yeah the name was my dad’s idea…

Anyway, today I’m going on an epic journey…through the human body!

So, wanna watch?

The trip starts as the human heads to the office lunch room, opens his lunchbox, and

finds me in there.

What else has he got here?

A turkey sandwich, some yogurt, hmm!

I see he’s taken a bite of his sandwich.

Oh!

Now it’s my turn!

He’s popped me into his mouth – it’s go time!

Gotta be honest, it’s pretty wet and warm in here.

The mouth is the gateway to the digestive system.

That system is designed specifically to transform food into useful nutrients that keep you energized

and help your cells grow and repair.

So, once you grab the first bite of whatever you’re eating, you turn on the digestion

machine.

As you chew, food is broken up into pieces to make the process easier.

Saliva comes in handy as it mixes with food and breaks it down even more.

That way, your stomach doesn’t have to digest whole chunks of food.

By the way, here’s a fun fact – the amount of saliva you produce in a year could fill

2 medium-sized bathtubs!

Almost a pool full of drool!

It’s really raining spit in here, ew!

Whoa, I better watch out for these teeth!

Wouldn’t wanna end up like Turkey Boy over there.

It’s hard since this guy’s using his tongue to roll food around his mouth and toward his

teeth.

I don’t really feel like becoming jam today, so I’m just gonna bypass all this chewing!

Down the chute we go!

Weee!!!

We’re now heading into the throat – they also call it the pharynx.

Uh-oh, fork in the road.

Which way do I go?

Eenie meenie miney moe –looks like this way we must go.

Hang on, I think I took a wrong turn.

Why is everything shaking?

Aw, poor human is coughing like crazy – someone give him a nice slap on the back.

There we go, coming back up!

Sorry, dude!

Phew, that was close!

Almost ended up in his lungs – that wouldn’t be good.

Alright, I’m back on the road, so let’s give it another try.

I’ve CORRECTLY turned into the swallowing tube that goes by the sophisticated name of

esophagus.

I like to call it the “food chute” but it’s a lot less spacey than I imagined!

I’m getting kinda squooshed in here.

Uh oh, how do I keep going down?

Ah, I see.

The muscles in the walls of this guy’s esophagus are squeezing behind me and relaxing in front

of me.

This is a process called peristalsis, and it’s what moves me through your digestive

system.

A couple seconds later, and we’ve now reached the end of the tunnel.

There’s a muscle here that opens up to let food into the stomach and keeps it from coming

back out into the esophagus.

It’s kinda like the TSA in a way.

I’m just a tourist here, sir, please let me in.

Yay!

I’ve passed through the valve and into the stomach.

It reminds me of a sac and … let me try those walls.

Wow, that’s a strong one – it’s all muscle.

I’m not surprised, actually.

The stomach holds, mixes, and grinds the food up into mush, so it has to be pretty strong.

Quite honestly, this doesn’t look too … oh my, what’s that?

That burns like crazy!

Ooh, ooh, hot!

I gotta get out of this stomach acid or else I’ll turn into liquid or paste like Turkey

Sandwich over there!

That’s okay, I’ve come prepared!

I brought this handy-dandy little device that’ll incase me in a protective bubble.

Your food usually doesn’t have this, but I got…connections.

It’s classified.

I just have to push this button...

There, now I can keep talking to you the whole way instead of turning into grape jelly.

Next stop – the small intestine!

This long coiled snaky organ is made up of 3 sections.

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!

Yep, that’s as long as a giraffe is tall…all stuffed into your insides!

I must say, it’s pretty warm in here.

Almost feels like a tropical resort, except I’m in an ocean of … bile!

Oh yeah, I’m protected in my little bubble, no worries!

Bile is crucial to digest fat and take all the waste out of your blood, so be thankful

your liver produces it.

Your pancreas also helps the process with some good enzymes.

And that thing over there that looks like a pear – that’s the gallbladder.

It’s located under the liver and keeps bile in it until the right moment comes.

Man, this thing really is coiled, huh?

I’m getting kinda dizzy from the twists and turns.

But no going back now – these contracting intestinal walls keep pushing me forward.

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!

Also known as the colon, it’s a muscular tube that’s 5 to 6 feet long.

Hold the phone.

Shh.

Do you hear that?

I’m not alone.

I’m surrounded.

They’re coming in closer.

It’s…It’s…bacteria!

There’s tons of them in here!

Uh-oh, is this person sick with some intestinal parasite or something?

Nah, your intestines need good bacteria to help them break down food, vitamins, and nutrients

so that your body can use them.

Sup, peeps?

Hey, what’s that little dangly thing over there at the entrance?

Ah, that must be the appendix.

It doesn’t do much besides house bacteria that might need to be released into the gut.

It’s also got some tissues that are useful for your immune system.

But it’s mostly a useless little thing, so people can still live without it.

Hey, if your appendix gets inflamed, a doctor will cut it out of you!

Really!

Looks like this guy still has his.

Good for you!

Anyway, we’re now in the large intestine, and I’m glad it’s a little roomier in

here.

Had I not grabbed my fancy top-secret protective bubble, I’d be talking to you now as a liquidy

yellowish mush of waste.

As these muscle contractions push me through the colon, I’d have all the water sucked

out of me.

My final form: stool.

Yep, poo, do-do, #2, feces, whatever you like to call it, it’s formed in the large intestine.

Still loads of bacteria all over the place.

They’re really hard at work, eh?

Well, there can’t be too little or too many – otherwise you’d have digestive problems

like food intolerances.

They also play a major role in your immunity, and that’s why you have trillions of them

in your gut.

Keep up the good work, guys!

I'm on my way through the left colon.

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.

It usually takes about 36 hours for what’s left of your food (not much now, just waste)

to reach this point.

But I’ve been speeding through this journey because I’ve got some other grape stuff

to do.

So let’s head to the rectum already.

Geronimo!!!

The rectum is a straight chamber that’s about 8 inches long.

It has special sensors, like this one or that one there, that let you know when there’s

something you should get rid of.

They send a signal to the brain when stool or gas wanna make their exit.

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!

Your stool makes its exit.

Buh-bye, pizza from yesterday’s breakfast!

What?

No one else here has cold pizza for breakfast?

Alright, then let me know down in the comments, what your typical breakfast looks like!

Anyway, when the moment isn’t exactly right to release stool just yet, your sphincters

contract.

Those rectum sensors help too so that the urge to release its contents disappears for

a while.

You should be happy your rectum and sphincters are working hard to keep stuff in when the

timing isn’t good.

Like when you’re driving to work, on a date, getting groceries, sleeping!

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!

Well, not sure if the human is ready, but I’d really like to go now.

Maybe I can hotwire these sensors to make my great escape.

Oh yeah, this guy is at work, isn’t he?

Um, this is gonna be awkward…Of course, normal food doesn't leave your body in such

a graceful manner.

You wouldn't even recognize what was what!

But as for me, Gilbert The Grape, I still have important things to do, so hey, bub,

let’s hit the john!

I’m outta here!

Byeee!

Well that was different.

Hey, if you learned something new today, then give the video a like and share it with a

friend!
