True or False: The pancreas does not contain myoepithelial cells.
this hepatic zone has the highest Kreb cycle activity
this hormone stimulates the release of glucose into the bloodstream
digestion begins in the oral cavity. This is due to what component of saliva?
this hormone stimulates the uptake of glucose, storage of glucose, and the phosphorylation and use of glucose.
secretion by exocytosis
the sinusoidal capillaries of the liver are classified as what?
polypeptide hormone that stimulates the duct cells of the pancreas to secrete a large volume of bicarbonate
the hepatocytes of this zone is the first to show ischemic necrosis
distinct mass of cells that constitutes the endocrine pancreas
salivary antibody
this exocrine secretion of the liver that contains degraded waste products and substances that bind to metabolites to facilitate absorption
Ito cells synthesize which type of collagen?
these structures carry bile to the hepatic bile duct
mode of secretion for salivary glands
the adult liver secretes an average ___L of bile a day.

polypeptide hormone that stimulates pancreas to secrete digestive enzymes
B cells of the pancreas secrete _____.
duct cells that signify the beginning of a pancreatic intercalated duct
venous supply of the liver in portal triad

QuestionAnswer
the cells of this hepatic zone are the last to die if blood circulation is cut from the liver and the first to regenerate.
this component of saliva aids in controlling the bacterial flora of the oral cavity
protein secreting cells
mucin secreting cells
storage form of iron in hepatocytes
specialization on the basal surface of hepatocytes project into this space, increasing absorptive surface area.
True or False: the sublingual glands are primarily mucous secreting glands.
True or False: In detoxification, the liver modifies toxins so that they are more water soluble and easily removed by the kidney.
secretion by membrane rupture
Intercalated ducts have been shown to secrete what ion into secretions?
a contagious viral condition that presents with swelling of the parotid gland.
____% of saliva is produced in the parotid gland
vitamin important in hepatic synthesis of prothrombin and other important clotting factors
these granules contain inactive forms of trypsin, chymotrypsin, amylase, lipase, and carboxypeptidase.
the basic unit of the salivary gland that consists of an acinus, an excretory duct, and intercalated duct

stellate sinusoidal macrophages
____ % of saliva is produced in the submandibular gland

contractile cells located in between the basal plasma membrane and the basal lamina as well as in the proximal portion of excretory ducts
plasma protein produced by the liver. regulates plasma volume and tissue fluid balance by maintaining the plasma colloid osmotic pressure
secretion by membrane budding
these type of glands have very well developed intercalated and striated ducts because these ducts modify the secretion by absorption of specific components of the secretion
