this hepatic zone has the highest Kreb cycle activity
this component of saliva chelates iron necessary for bacterial growth
True or False: In detoxification, the liver modifies toxins so that they are more water soluble and easily removed by the kidney.
plasma protein produced by the liver. regulates plasma volume and tissue fluid balance by maintaining the plasma colloid osmotic pressure
striated ducts secrete what 2 ions into acinar secretions?
QuestionAnswer
the sinusoidal capillaries of the liver are classified as what?
site of exchange of materials between the blood and liver cells
D cells of the pancreas secrete _____.
stellate sinusoidal macrophages
mode of secretion for salivary glands
this component of saliva aids in controlling the bacterial flora of the oral cavity
