an important vitamin that is required for th esynthesis of rhodopsin
the proteins within hepatocytes that facilitate the oxidation of toxic substances
True or False: The parotid gland is primarily serous.
these structures carry bile to the hepatic bile duct
this exocrine secretion of the liver that contains degraded waste products and substances that bind to metabolites to facilitate absorption
the sinusoidal capillaries of the liver are classified as what?
this hormone stimulates the uptake of glucose, storage of glucose, and the phosphorylation and use of glucose.
protein secreting cells
True or False: In detoxification, the liver modifies toxins so that they are more water soluble and easily removed by the kidney.
duct that leads from the acinus
the liver receives the majority of its blood supply from what?
Kupffer cells are derived from?
