13

What is food that is semi-solid and 'soapy' in the area of the duodenum called?

Chyme

14

Which hormone stimulates the secretion of gastric acid and intrinsic factor, as well as pepsinogen? It also promotes gastric and intestinal motility as well as mucosal growth. From where is it released?

Gastrin

Released from gastric antrum, G-cells (duodenum) and the pancreas

15

Which hormone inhibits the secretion or action of various hormones, including secretin, CCK, VIP, and gastrin? From where is it released?

Somatostatin

Stomach, small intestines, and D-cells (pancreas)

16

Which layer of the stomach provides nutritional support to the mucosa? What is another frunction of this layer?

Immune system cells 

17

What substances do neuroendocrine cells release?

Enterocromafin (Serotonin, Histamine)

Somatostatin

Gastrin

18

The parietal cells of the stomach release gastric acid as well as intrinsic factor. Where does most intrinsic factor come from in the dog?

Pancreas

19

Which enzyme aids in the digestion of protein in the stomach? Fat?

Pepsin

Gastric lipase

20

T/F: Fatty meals pass throught the stomach faster that meals low in fat, partly because fat lubricates the stomach.

False, super false 

Fat slows movement so lipase has time to work
