Is Daddy OK?
Jenny thought that the liver had something to do with energy, but she wasn't sure.
Dr. Green showed Jenny a picture of the liver. "The liver is one of the most important organs in the body," said Dr. Green.
"One very important thing that the liver does is to help clean up the body. Air, food, and water often have small amounts of bad substances in them, and the liver tries to break down these things so they don't hurt us.
"The liver also manages the energy we get from food, and it makes sure that all of our tissues get just the right amount of water."
"The liver looks really big," said Jenny.
"Yes," agreed Dr. Green. "It's the biggest organ in your body."
