What does the liver do? – Emma Bryce


There’s a factory inside you
that weighs about 1.4 kilograms and runs for 24 hours a day. This is your liver,
the heaviest organ in your body, and one of the most crucial. This industrious structure
simultaneously acts as a storehouse, a manufacturing hub, and a processing plant. And each of these functions involve
so many important subtasks that without the liver,
our bodies would simply stop working. One of the liver’s main functions
is to filter the body’s blood, which it receives in regular shipments
from two sources: the hepatic artery
delivers blood from the heart, while the hepatic portal vein
brings it from the intestine. This double delivery
fills the liver with nutrients, that it then sorts, processes and stores with the help of thousands
of tiny internal processing plants, known as lobules. Both blood flows also deliver the oxygen
that the liver needs to function. The blood that is received
from the intestine contains carbohydrates, fats, and vitamins and other nutrients
dissolved in it from the food you’ve consumed. These must be processed in different ways. In the case of carbohydrates, the liver breaks them down
and converts them into sugars for the body to use as energy
when the filtered blood is sent back out. Sometimes the body
has leftovers of nutrients that it doesn’t immediately require. When that happens,
the liver holds some back, and stacks them in its storage facility. This facility works like a pantry for future cases when the body
might be in need of nutrients. But the blood flowing into the liver
isn’t always full of good things. It also contains toxins
and byproducts that the body can’t use. And the liver monitors these strictly. When it spots
a useless or toxic substance, it either converts it into a product
that can’t hurt the body or isolates it and whisks it away, channeling it through
the kidneys and intestine to be excreted. Of course, we wouldn’t consider
the liver a factory if it didn’t also manufacture things. This organ makes everything
from various blood plasma proteins that transport fatty acids
and help form blood clots, to the cholesterol
that helps the body create hormones. It also makes vitamin D
and substances that help digestion. But one of its most vital products
is bile. Like an eco-friendly treatment plant, the liver uses cells called hepatocytes to convert toxic waste products
into this bitter greenish liquid. As it’s produced, bile is funneled
into a small container below the liver, called the gallbladder, before being trickled into the intestine to help break down fats, destroy microbes,
and neutralize extra stomach acid. Bile also helps carry other toxins
and byproducts from the liver out of the body. So as you can see, the liver is an extremely efficient
industrial site, performing multiple tasks
that support each other. But such a complex system
needs to be kept running smoothly by keeping it healthy and not overloading it
with more toxins than it can handle. This is one factory
we simply can’t afford to shut down.

  1. I don't have a gallbladder anymore so I have to be careful on what I'm eating. I have to take care of my liver more.

  2. Your kidneys carried urine to your liver then your liver carried urine to your bowels into your bowels movement.

  3. and yet many people believe that organism was created by mindless evolution, rather than super intelligent designer

  4. Isn't skin the heaviest organ in the body???

    You said liver.

    If my one is wrong then make mine correct

  5. From 2:50 to 3:00 it sounds like a commmercial offering jobs at the liver.

    "Come, work with us in the liver, the body's biggest facility"

  6. Background music is a bit too loud this time distracting attention from narrator's voice. Otherwise, awesome as always!

  7. Excellent video, loved each aspect of it. Only suggestion is that while the music and information flowed SO well together, the music got so good that I started jamming to it instead of listening to you 😂, maybe turn down the volume of the background music just a little bit in other videos so that your voice is the prominent one! 🙂

  8. Heart: if he's(liver) that important for y'all…may be I'll shut down for a couple of days..how'll dat work out y'all…!!!!

  9. Scientist understand how organs function and what they are specifically meant to do but deny the fact that this complex machine we have inside of us didn’t come by accident or ‘millions of years of evolution’ as they say. It is god, the best designer, who has put it together so that humans and all the other creatures can worship him alone. You are In a great if you deny this and will find out when you die.

  10. I've just watched this same topic but in full scientific type explanation.. I only understood half of it so I searched again then found this… Gotta admit i understood this more accurately.. Thank you

  11. Well, my liver is on recovery because last month I was on a motorcycle accident, I was the passenger and my cousin was the driver when he fell asleep then ran to a truck which I quickly swung my body and my cousin's but we were speeding to fast which led to my cousin's broken shoulder and I receive all the impact from the truck that causes my liver contusion, I was on the middle of the road vomiting so many blood because of my liver was bleeding and I can't move my body, I was about to get surgery but a miracle happened, my uncle gave me an oil that is like a healing potion which is called "himag" here in the Philippines and made me drink it, after that my stomach was aching so much like my life was about to end but then I can't stop myself from vomiting that made me vomit around so many people because I was about to get a Contrast CT scan and believe me or not, my vomit was clear oil covering what's looks like blood that would've been a bloodcloth without that himag my life would've ended differently.

  12. All this complexity and accuracy is in your body.
    God has said something like this in the Quran,
    "We will show them Our signs in the horizons and within themselves until it becomes clear to them that it is the truth. But is it not sufficient concerning your Lord that He is, over all things, a Witness?"
    When this verse was revealed, neither the Prophet Muhammad nor anyone at that time had access to accurate biological information as we do today.
    Today, we see the signs of God's creation around us as well as in ourselves.
    Worth thinking.

  13. And yet people still believes in Evolution.
    This is obviously a product of intelligence and design. Built for specific purpose and not some blind chance.

  14. Informative one, please reduce the BGM volume by some notch, so that the focus is on the information. Thank you!

  15. The BGM… It goes so well with the explanation
    Also it keeps getting my attention which is really getting annoying now

  16. I just ate a whole pizza
    Liver im sorry! Dont break up with meeeeee😭😭😭😭😭 i wont over load you more. Ill be good girl and eat my veggies!

  17. You don't mention the most striking feature of the liver, its ability to regenerate itself… Up to a point of course, still its regenerative ability is so good that you can donate a piece (lobule) of your liver and in a couple of months it would be as good as new. The Greek knew this, hence the Prometheus myth and his eternal punishment.

  18. So why are we taking medicines in , why is alchohol pushed at us . Look after your liver people , big pharma is is false profit .
