5

Parotid gland secretions- watery dilute saliva

Submaxillary gland- mucous and watery

Submandibular- Mucous and watery

6

See Ion concentrations vs flow rates chart

ok

7

As you move from the Acinus of the salivary gland to the duct opening, how do concentrations change>

You lose NaCl, water is impermeable so the amount of water stays the same and the concentration of water rises. Bicarb caoncentration goes up as does K

8

Parasympathetic stimulation leads to what response in the salivary glands

secretion, vasodilation, myoepithelial cell contraction, metabolism and growth of the glands
