What is the anatomy of the liver?
Anatomy of the liver The liver is located in the upper right-hand portion of the abdominal cavity, beneath the diaphragm, and on top of the stomach, right kidney, and intestines. Shaped like a cone, the liver is a dark reddish-brown organ that weighs about 3 pounds.
The liver has two large sections, called the right and the left lobes. The gallbladder sits under the liver, along with parts of the pancreas and intestines. The liver and these organs work together to digest, absorb, and process food.
Why does the liver have 2 lobes?
The liver has two lobes — the right and the left. Each lobe is made up of thousands of hexagonally-shaped lobules. These lobules are very small. These small blood vessels diffuse oxygen and nutrients through their capillary walls into the liver cells.
How does stuff get into the liver?
“Anything that is eaten or consumed, whether it’s food, alcohol, medicine or toxins, gets filtered by the liver. Once we ingest food, it is digested by the stomach and intestine, gets absorbed into the blood and goes to the liver,” Kwon says.
What are signs that your liver is struggling?

- Fatigue and tiredness.
- Nausea (feeling sick).
- Pale stools.
- Yellow skin or eyes (jaundice).
- Spider naevi (small spider-shaped arteries that appear in clusters on the skin).

- Bile production and excretion.
- Excretion of bilirubin, cholesterol, hormones, and drugs.
- Metabolism of fats, proteins, and carbohydrates.
- Enzyme activation.
- Storage of glycogen, vitamins, and minerals.

Can you live without a liver?
The liver performs essential, life -sustaining functions. While you can ‘t live without a liver completely, you can live with only part of one. Many people can function well with just under half of their liver. Your liver can also grow back to full size within a matter of months.
Why is the liver so important?
Functions of the Liver The liver is an essential organ of the body that performs over 500 vital functions. These include removing waste products and foreign substances from the bloodstream, regulating blood sugar levels, and creating essential nutrients.
Which lobe of liver is bigger?
The left and right lobes are the largest lobes and are separated by the falciform ligament. The right lobe is about 5 to 6 times larger than the tapered left lobe. The small caudate lobe extends from the posterior side of the right lobe and wraps around the inferior vena cava.
What is the normal size of right lobe of liver?
Pfahler (1), in a recent study of liver measurements, demonstrated the average length of the right lobe to be 21.3 cm. and the average thickness 12.8 cm.
How does the blood leave the liver?
Blood leaves the liver through the hepatic veins. This blood is a mixture of blood from the hepatic artery and from the portal vein. The hepatic veins carry blood to the inferior vena cava—the largest vein in the body—which then carries blood from the abdomen and lower parts of the body to the right side of the heart.
Is your liver bigger than your stomach?
It’s a dark red wedge about the size of a football that weighs around 3 pounds. Your liver fills the space under the right side of your rib cage and nestles on top of your stomach. It’s made up of two parts called lobes — a smaller left lobe and a bigger right lobe.
How long does it take for liver to process food?
Minutes after you eat a meal, as nutrients rush into your bloodstream, your body makes massive shifts in how it breaks down and stores fats and sugars. Within half an hour, your liver has made a complete switch, going from burning fat for energy to storing as much glucose, or sugar, as possible.
Does the liver heal itself?
The liver is very resilient and capable of regenerating itself. Each time your liver filters alcohol, some of the liver cells die. The liver can develop new cells, but prolonged alcohol misuse (drinking too much) over many years can reduce its ability to regenerate.
