Q
Liver Function
A
Exocrine:
•Synthesis and secretion of bile
Endocrine:
- Synthesis and secretion of plasma protein
- Glucose homeostasis

- Storage of fat soluble vitamins
7
Q
Liver Functions - Synthesis and secretion of bile
A
- bile salts for emulsification of fats in small intestine
- conjugation and excretion of bilirubin
8
Q
Liver Functions - Synthesis and secretion of plasma proteins
A
- albumin,
- clotting factors eg. prothrombin,
- carrier proteins eg. transferrin,
- etc.
9
Q
Liver Function - Glucose Homeostasis
A
- Glycogen synthesis from glucose
- Glycogenolysis - breakdown of glycogen to glucose
- Gluconeogenesis - de novo synthesis of glucose
10
Q
Liver Function - Amino Acid Homeostasis
A
- Synthesis of non-essential amino acids
- Breakdown of excess amino acids, production of urea
11
Q
Liver Function - Lipid Metabolism
A
• Synthesis of cholesterol

Q
Pancreas
A
•The pancreas is a mixed exocrine and endocrine gland: the exocrine portion secretes digestive enzymes that are delivered via the main pancreatic duct to the duodenum; the endocrine portion is comprised of the Islets of Langerhans
21
Q
Pancreatic Acinar Cells
A
- pancreatic acinar cells are large pyramid shaped epithelial cells; the perinuclear cytoplasm is basophilic due to abundant rough ER, and secretory granules are often visible in the apical cytoplasm.
- The acinar cells secrete digestive enzymes and enzyme precursors (= zymogens) including trypsinogen, chymotrypsinogen, procarboxypeptidase, ribonuclease, deoxyribonuclease, triacylglycerol lipase, prophospholipase A2, elastase, and amylase.
- These enzymes are synthesized in inactive forms and are not normally activated until they reach the lumen of the small intestine where they encounter the brush border enzyme enteropeptidase. This enzyme converts trypsinogen to trypsin and trypsin activates the other enzyme precursors.
22
Q
Intercalated Duct Cells
A
- intercalated duct cells secrete a bicarbonate-rich fluid for neutralizing stomach acid.
- They are low cuboidal epithelial cells with clear cytoplasm
