Pancreatic and Salivary Secretion--------------------------END

Question 1

gland structure for pancreatic juice?

Answer 1

Ducts, acini, islets

Question 2

gland structure for saliva?

Answer 2

Ducts and acini

Question 3

what is the composition of pancreatic juice?

Answer 3

isotonic, alkaline, many digestive enzymes, regulatory molecules, cofactors

Question 4

what is the composition of saliva?

Answer 4

Hypotonic (ducts impermeable to H2O), alkaline, some digestive enzymes, protective molecules (IgA)

Question 5

what is the flow rate for pancreatic juice?

Answer 5

Similar to plasma at low flow rate
Na and K secretion does not vary with flow rate
HCO3 increases with flow rate, Cl decreases

Question 6

what is the flow rate for saliva?

Answer 6

Similar to plasma at high flow (decreased contact time)

Exception: HCO3 increases with flow rate due to selective stimulation

Question 7

what is the stimulation for pancreatic juice?

Answer 7

Hormonal (CCK, secretin) and neural (ACh)

Question 8

what is the stimulation for saliva?

Answer 8

Predominantly neural (ACh and NE)
