Lesson Transcript

Did you know one of your organs can regrow itself? That's right--your liver can regenerate, or regrow itself. Learn more about the liver, where it is in the body, and the amazing things it does to keep you healthy.

What Is the Liver?

What is reddish-brown, weighs three pounds, and is the size of a football? If you guessed your liver, you're right!

When we think about important organs in our bodies, we often think about the brain or heart. While your brain and heart are certainly essential, your liver is also important. Your liver is an organ that cleans the blood, helps digest food, and stores energy.

Your liver sits just under your rib cage in the upper right part of your stomach, and it has two main parts called lobes. The right lobe is larger than the left lobe, so the liver looks like a lopsided triangle!

The liver is a very unique part of your body. It's the second-largest organ in your body (the skin is considered an organ and is the largest).

The liver also has the amazing ability to regenerate, or regrow itself. That's right, if liver tissue is damaged, a liver can regrow itself from as little as 25% of its original size. Another amazing fact about the liver is that it's made of 96% water!

The liver does many important things, but its four main jobs are: cleaning your blood, storing energy, making bile, and balancing cholesterol levels. Let's discuss these more.

Cleaning Blood & Storing Energy

Your normal body functions sometimes produce toxins, substances that act like poison in the body. For example, when you eat something, your body breaks it down into nutrients, and toxins are also made during this process.

The liver cleans your blood by removing harmful toxins. In this way, the liver acts like a garbage collector, making sure your blood stays clean.

The liver also acts like a warehouse for energy. When you eat something with carbohydrates, like fruit or bread, your body breaks down the carbs into a sugar called glucose.
