Key Stage 4
Meaning
The liver is an organ used to detoxify blood and to produce bile to aid the digestion of lipids.
About The Human Liver
- When muscles do not get enough Oxygen during exercise they break glucose down into lactic acid for energy. The liver removes this toxic lactic acid from the blood by converting it back into glucose.
- The liver clears dead red blood cells and breaks them down into bile which is stored in the gall bladder. The bile is then used to emulsify lipids which increases their surface area making them easier to chemically digest.
- When food is absorbed into the blood it goes through the hepatic portal vein straight to the liver which removes toxins from the blood before it is sent to the rest of the body.
