The liver cleans our blood. Blood enters the liver full of oxygen through the hepatic artery directly from the heart. It also enters the liver full of nutrients via the Portal Vein. Inside the liver, the blood is mixed together and filtered to remove toxins, wastes and chemicals.
Just like a honeycomb, the liver is made up of hexagonal chambers. In the liver each chamber is called a lobule. The main vein and artery which enter the liver are subdivided and enter the lobules at the corners. Inside the lobules blood is cleaned and bile used in the digestive system is produced.
We created a model of the liver using toilet paper rolls, yarn, staples and paper towel. David Macaulay's The Way We Work is the reference we have been using to inspire our human body science activities.
