Consider the Liver
Let’s start with that word liver.
We’ll get to some cool news about imaging the livers in a minute, but let’s start with etymology.
It’s from the Old English word lifer, which traces back to Germanic roots “life” or “fat.” And in early Germanic languages, lifere was tied to the concept of life because the ancients viewed the organ as essential to living and physical health.
They weren’t wrong!
In the ancient Greek language, the liver was called hèpar. Notice that’s the root for words like hepatitis. In Latin, however, the organ was called ficatum, meaning “stuffed with figs.” Why? The word was derived from the Roman culinary practice of feeding figs to geese to fatten their livers.
The liver is the largest of the vital organs. Vital, yes. You can’t live without it.
At any one time, your liver holds 13 percent of your body’s total blood supply. When it’s functioning at a high level, a liver will filter roughly 1.7 liters (nearly half a gallon) of blood every single minute.
The liver contains 300 billion specialized working cells packed into tiny units called lobules. It also produces up to one liter of yellow-green digestive fluid every day to help break down fats. That fluid is called bile.
The liver’s talent at regeneration are legend. Even if 70 percent of the liver is extracted, the remaining tissue can regenerate and restore the organ’s function.
The liver stores vitamins and minerals until the body needs them. These include vitamins A, D, E. K, and B12 as well as iron and copper. The liver can produce glucose to maintain regular blood sugar levels. This is called gluconeogenesis. The liver also produces proteins that are essential for blood to clot properly. And the liver’s so-called “Kuppfer” cells can engulf and destroy bacteria and other harmful particles. (German anatomist Karl Wilhelm von Kupffer discovered these cells in 1878.)
And that brings us cirrhosis.
Quick note: cirrhosis, as a word, has its roots in another Greek word, kirrhos. Kirrhos means yellow-orange in Greek and osis is condition. “The yellow-orange condition.”
Advanced liver disease cause extensive scarring, which produces the cirrhosis. That cirrhosis prevents the liver from functioning properly. But researchers, according to the National Institutes of Health in a March 2026 article here, don’t fully understand how the liver changes internally during cirrhosis. “Current models for studying the liver’s structure are mostly flat, 2D cultures. These don’t show the organ’s complex internal 3D structure or how it changes during liver diseases.”
And here’s the news: research funded by the NIH has developed a new “3D” reconstruction that shows the liver down to a cellular level.
It’s called the LiverMap pipeline. (Results of the research were published in Science Advances in February, 2026). The approach revealed “architectural changes to occur during cirrhosis. Cells and blood vessels were rearranged across several lobules,” the NIH article states. “Cirrhotic tissue had fewer cells making a key liver enzyme. It also had fewer central veins than healthy liver tissue. The network of ducts that transport bile, a substance that aids digestion, became more fragmented as well.”
But the scientists still have work to do. The plan is to do a “complete lobule” reconstruction. (Each human liver has between 50,000 to 100,000 “hepatic lobules.”) Down the road? The prospect of using 3-D printers to generate tissue that could be used to replace diseased portions of the liver.
It’s … progress. It’s one big step. Congratulations to all those taking a deeper, closer look at the body’s largest vital organ.
