When cells are ——— or ———- and ——- off, usually that ————— ———— that was previously full of living cells becomes ————, meaning it becomes ———- with heaps and heaps of ———— and forms ———— ———-.

So when your——— is ————- forced to process ———— like in ———- ————— ————, or subject to a ———- ———- for a ——— time like in ———-, or anything else that causes a ——- - ——- or ———— ——— of ——- cell or —————- ————- and ————, your ——— can become seriously ——— and ————— to the point where it’s no longer —————-, at which point it becomes ———— and in the ———- we call this process ————-.

Because it’s usually ————-, ———— is often referred to as “——— - ———” or “—— - ——-” ——— ————.
When liver cells are ————-, they start to come ———- and form what are called ———- ———. You can think of these as ———— of ———— ————- cells. These are one of the classic signs of cirrhosis and are why a ————- ———- is more ———- as opposed to a ————, healthy liver.

Also with ———- ————- tissue, you’ll see that in ————- these ———- of cells or —————, is ———- ———- and ———.
Here’s a classic histology image of cirrhotic tissue, this ———- of cells in the middle is the —————- ————, and these ——— ———- surrounding it are the ————- of ———- from the process of —————-.

If we zoom out a bit and look at it with the naked eye, we’ll again see these ———-, which have ———— ——— ——— in ———-.
How do these ———— of ————- ———- form though? Well ————- is a process mediated by special cells called ———- cells, that sit ———— the ————- and —————, known as the —————- ———-.

Here’s a pretty basic layout of the basic ————- ——— of the liver, you’ve got the ——— ——— and —————- ——— that ———— into a ————, which then goes into the ———- ————-, and these are all ————- with ————-.
Along with these though you’ve also got a ———— ———-, and all ———— constitute a ———- ———-.

So the ———— ————, which literally means “————- the ————— ———”, and ——— cells are about here. And usually in ———— tissue, these guys’ main function is to ———- ———— ——- and are otherwise considered ————, or sort of ———-. When the ———- are ———- though, they ———— ———— ———— that “—————-” and ———— the ————- cells.

When ————-, the ————- cells ———- ———— ———, ————, and start —————- ————- —————- ————- ———-, or ——— - ———-, which then causes them to produce —————, which is the main ingredient in ————- ————, —————-, and ———- ————.
As this ———- tissue builds up, it starts to ————- the ——— ———— and —————-.

It’s thought that in a healthy, normal state, these cells play key roles in the natural ——— - ——— process, but when the liver cells are ————- ——, the ———— cells are ———— ————— and so they constantly produce ————- and ———- that lead to ————-.
And this is when ————- due to —————- start to crop up.

As the ———- ——— and ————- become ———— and ——- on the ——— ———-, their ——- starts to ——- up, leading to ————- (or ———-) ——————, which is this ————— pressure in the ———- ——-.
.—————- ———- ———— pressure means that ———- in ————- ———— is ——— likely to get ————— into ——— and ——— tissues into ————- ———— ————- like the ———— ———-.

That’s why ———— leads to ————— ——— ————, a condition called ———-, and can result in other complications like —————- —————- and ——————, where the spleen becomes —————- because all this ——— and ———— can’t get ——— the ————, and ——- up into the spleen.
In the same way, your ————— ———— starts diverting ———- ———- from the ——— because of the ————— ———- ————-, this is known as a ———— —————.

.———— ——— follows the path of —————- ————- and ——- ————— from the ———- ——— and towards the ————— ————- of ————.
Though not fully understood, these changes in ————- ————- ultimately trigger ———— —————-, so ————— ————— in the ———— ——————, which ————— ———— ————- through the ————, leading to —————- —————- ———— ————-, where ————- ———— follows ———- ————.

The ————- ———-, ———- ———, and ————— of —————- from the ———- ———- essentially ———— the number of ———— ———— ———, and the number of ———— ———- ————— in general.
As you have less and less of these ———— ————- ————- ————, your liver becomes less and less able to do its job of ——————.

detoxification
When your liver isn’t ————- your ————, these ———— can get into the ———— and start causing ———— ————, a condition known as ————- —————-.
Although there are several —————- that are thought to contribute to the ————— of these ———— —————-, the best understood factor is ———— in the ———-, which is produced mainly in the —————- ————; usually the liver plays a vital role in —————- ————- and stopping it from going into the ————— ————-.

As more of these and other ——— get into the ———-, patients might develop ———-, where they have ————- or ———— ——— when ————-, and as even more ———— ———- up, eventually patients can progress to a ————.
Also, since the liver plays a big role in ————— ———— into ————— ——— that can be removed from the ———- and —————, patients can also experience —————- due to ————— ————— in the blood, like —————, ————— ————-, and ————- —————-.

And, since the liver usually ————- ————, ————- ————- ————- in the blood from ——— - —————- liver can lead to ————-.
Another important job of the liver is producing —————-, so again, if the liver’s not ———— right, you can have a ———— amount of ———— in the blood, or ————-.

Finally, the liver helps in making ———— ——- or ———- that help ———- your blood, so when you aren’t producing these ———— ———-, you can develop issues related to your ability to ———- blood, which you need in order to stop ——— ——— after an ————.
To recap the general symptoms of cirrhosis, ———— on, with a ————— amount of ———- and ———-, we call it ————— ———-, meaning the liver can still do a lot of its job.

In this case, somebody with cirrhosis might not have any ————, or have ————- ———- like ———— ———-, ————-, or ————-.
Later on, though, with —————- ————, the liver progresses to —————- ————, and can’t ————- properly.
At this point many of the described —————- start to develop, like ———— and ———- or ———- ————- ————, ————— ————- leading to ————-, and easy ————— from ———— —————- ————.

For ————-, the “———- ———” is a ————- ———-, taking a ———- ————— of the ———— tissue examine under a ————-.
Common lab findings include —————— ————- —————, as well as —————- ————- ———— like ————- ——————, (AST) and ———— ——————- (ALT), where ————- is usually more elevated than ————, ————— ————— (ALP), and —————- —————— —————-, and ——————-, or ————— ———— —————.

As to —————, generally the —————- in cirrhosis is —————-, so first of all it’s important to prevent —————- ————- ————- by identifying the —————- ———— and ————— that, for example stopping ————— ————- or ———— treatment for those with ————— ———. With ————- cirrhosis, though, where the liver stops —————-, a ———— ———- might be needed.
