Question 14

TF in the par cell H+ is made from metabolism of CO2 and H20

Answer 14

T

Question 15

Describe the route of K+ in the parietal cell

Answer 15

exchange with Na on serosal side once n cell goes down conc gradient into lumen then flows back into par cell because H+ goes down its conc. gradient(they r exchanged)

Question 16

in the parietal cell of stomach during production of HCL HCO3 accum on the serosal side HCO3 acum on the lumen side HCO3 andHCL cotransport to lumen side

Answer 16

HCO3 accum on the serosal side(cap)

Enterchromatin cell

Answer 21

makes histamine

andstim Par cell

Question 22

SM plexus

Answer 22

act by vagus and stimulates

G cell, enterchrom.cell and Par cell

Question 23

interfering with Histamine will turn of HCL production in stomach

How?

Answer 23

block H2 receptor on par cell

Question 24

interfring with which pump in the luminal side of stomach will stop HCL procution

H/K exchanger

HCO3/CL exchanger

Na/K exchanger

Answer 24

H/K exchanger

other two are on serosal side

Question 25

tf D cell sense ph\<2

Answer 25

T turns of HCL formation

Question 26

tf in cephalic phase d cell turn off

Answer 26

F happens in gastric phase when food comes in and binds H+ ions raises the Ph--\> d cell off

Question 27

in the gastric phase what hormone triggers g cells to make gastrin

Answer 27

Pepsin inc to yield AA and peptides

Question 28

h binds to food and is bufered

Answer 28

gastric phase

Question 29

intestinal phase is triggered when

Answer 29

food enters SI

Answer 31

CCK

Question 32

turns stomach activity off

Answer 32

GIP

Question 33

glucose binds to receptors in

Answer 33

SI and forms GIP during intestinal phase

Question 34

TF glucose tells pancreas to make insulin during gastric phase

Answer 34

F during intestinl phase

Question 35

When small amt of fod is ungested ph is high ur in the gastric phase vagal activity is stimulated

Answer 35

vagal activity is stimulated
