False-colour scanning electron micrograph (SEM) of the cell structure within a lobule of the liver. Hepatic cells (shades of brown) surround sinusoids (channels, blue) in a three-dimensional network. Blood cells (red) flow through these sinusoids to link up to a central vein. In this process of blood flow, liver cells are specialized to clean the blood of microorganisms, toxins, aged cells, and debris. Bile formed by liver cells is released into tiny bile capillaries (cholangioles, green). Bile then enters the gall bladder to be used for digestive purposes. The liver also synthesizes Vitamin A.
