So the liver can actually expand, so the blood vessels inside the liver are capable of expanding and that means the liver can actually act as a storage system for blood. So the blood vessels in the liver can expand to store extra blood that might be needed by the body in a future time. Now, specialized phagocytic cells inside the liver, known as cup force cells, are responsible for fagatizing, for eating up, engulfing and breaking down infectious bacterial cells that are found inside our blood plasma and found inside our liver. And on top of that, these same copper cells can also recycle and break down the old red blood cells that no longer function properly. So these red blood cells are also known as erythrocytes. Now, function number four of the liver is to basically store important types of vitamins such as, for example, vitamin D, as well as iron that are essential for our body.
