1. what are the components of GALT
Peters patches (PPs) and isolated lymphoid follicles constitute the major part of GALT, but the appendix is

2. what are the components of NALT?
in humans, NALT consists of the lymphoid tissue of waldezyers pharyngeal ring, including the adenoids (the
nasopharyngeal tonsil) and the paired palatine tonsils, scattered isolated lymphoid follicles may also occur in

3. rodents lack tonsils, but do have paired
NALT structures dorsally in the floor of the nasal cavity and also salivary glands

4. what are the components of BALT
not generally detectable in normal lungs of adult humans

5. waldeyers ring
an interrupted circle of protective lymphoid tissue at the upper ends of the respiratory and alimentary tracts

6. composition of saliva (9)
~99% water
Na
K
Ca
Mg
bicarbonate proteins
enzymes
muffins
nitrogenous products such as urea and NH3

7. types of saliva (3)
serous mucos mixed serous and mucos

8. serous saliva is the main product of the
parotid glands

9. mucos saliva is the main product of the
minor glands

10. mixed serous and mucos saliva is the main product of the (2)
sublingual and submandibular glands

11. functions of saliva (6)
lubrication and protection
buffering action and clearance
maintenance of tooth integrity
antibacterial activity
taste and digestion
saliva production is 750-1000 mL/day
