1. what is a gland
an organised cluster of secretory units

2. functions of digestive glands
lubrication protectiondigestion and absorption

3. portions of salivary gland
secretory and duct regions

4. two types of cells (acini)
serous and mucous
held together by myoepithelial cells

5. duct system in salivary gland
intercalated -> striated -> interlobular -> interlobar -> principle

6. three types of salivary gland
parotidsubmandibularsublingual

7. parotid gland produces
water (serous) solution, about 25% total

8. submandibular gland produces
both serous and mucous, 70% total

9. sublingual gland produces
mucous secretion, 5% total

10. main enzyme in saliva
alpha amylase

11. main components of saliva
proteins, glycoproteins, ions, water IgA

12. arrangement of cells in saliva
secreter portions arranged in acini with the 3 cell types

13. type of epithelium in salivary gland
stratified squamous

14. autonomic regulation of salivary glands
parasympathetic most important
ach stimulates primary secretion, get large amounts of watery saliva

15. pancreas exocrine structure
compound tubulocacinar gland
