Liver factoids:
 * Starter**
 * Babylonians considered the liver to be the seat and mirror of the soul
 * 2nd largest organ in the body (weighs in at 1.2-1.5 Kg)
 * holds 13 percent of the body's blood supply
 * principle organ responsible for generating body heat
 * regulates the levels of nutrients in the blood
 * removes toxins from the blood
 * if toxins cannot be broken down the liver stores them
 * plays a role in immunology
 * it can regenerate damaged tissue very quickly, in a matter of hours
 * we know of over 500 different functions that it performs


 * Assessment statements** (IBO notes added to some point to clearly indicate what needs to be understood and what does not)
 * H.4.1 || Outline the circulation of blood through liver tissue, including the hepatic artery, hepatic portal vein, sinusoids and hepatic vein. Include structural difference between sinusoids and capillaries. Reference to lobules or acini is not required. ||
 * H.4.2 || Explain the role of the liver in regulating levels of nutrients in the blood. ||
 * H.4.3 || Outline the role of the liver in the storage of nutrients, including carbohydrate, iron, vitamin A and vitamin D. ||

 * H.4.5 || State that the liver has a role in detoxification. ||

 * H.4.7 || Explain the liver damage caused by excessive alcohol consumption. ||
