Front 1

Exocrine pancreas

Back 1

-Produces a wide spectrum of degradative enzyme to help digest food

-stored within cytoplasmic granules of pancreatic acinar cells (zymogen granules).

-secreted in a watery alkaline fluid that serves to neutralize the gastric acid.

Front 2

Structure of the exocrine pancreas is very similar to the parotid gland but…

Back 2

1. Epithelium of intercalated duct projects into the lumen of the acinus-centroacinar cells

2. No striated ducts in the pancreas

3. Presence of islets in the pancreas

Front 3

Major digestive glands

Back 3

1. Major Salivary glands-
Parotid, Submandibular/Submaxillary, Sublingual

2. Exocrine Pancreas

3. Liver

Front 4

Gland Organization

Back 4

Duct system-
Simple- single unbranched duct
Compound- branching duct system

Cellular organization of secretory portion
tubule-straight, coiled, branched
acinar-spherical collections of cells

Front 5

Saliva

Back 5

1. Complex fluid-product of serous and mucous glands

2. Lubricate mucosa of oral cavity
Dissolve food for taste bud function
Moistens food for swallowing

3. Digestive-contains amylases and lipase to facilitate digestion.

4. Protective- host defense functions
lysozyme
lactoferrin
immunoglobulin A produced by resident B cells and plasma cells

Front 6

Parotid

Back 6

Produces saliva
Largest salivary gland (serous gland with serous acini)

Front 7

Saliva produced by

Back 7

parotid, submandibular/submaxillary and
sublingual salivary glands- compound tubuloalveolar glands
with ducts emptying into the oral cavity.

Front 8

Submaxillary/mandibular gland

Back 8

mixed with serous> mucous acini

Front 9

Sublingual gland

Back 9

mixed, with mucous > serous acini
