11
New cards

4 major processes of the GI tract

1. Secretion

2. Digestion

3. Absorption

4. Motility

12
New cards

Cirrhosis + jaundice

scarring of the liver

13
New cards

Peristalsis

the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wavelike movements that push the contents of the canal forward.

14
New cards

2. Mucosa

3. Submucosa

4. Serosa

15
New cards

Salivary Anylase

an enzyme that breaks down starch into smaller particles and eventually into disaccharide maltose in the mouth

16
New cards

peritoneum

a multilayered membrane that protects and holds the organs in place within the abdominal cavity

17
New cards

enteric nervous system

the nervous system of the digestive tract (submucosal plexus + myenteric plexus)

18

21
New cards

Stomach takes about ___ - _____ hours to empty

2-6

22
New cards

paracrine factors

Local signaling molecules affecting nearby cells through interspatial fluid

23
New cards

celphalic phase

sight, smell, taste, thought of food; stimulates

24
New cards

gastric phase

phase of gastric secretion that begins when food enters the stomach

25
New cards

intestinal phase

Stage in which the duodenum responds to arriving chyme and moderates gastric activity through hormones and nervous reflexes

26

-carbonic anhydrase

27
New cards

Regulation of stomach acid

-gastrin

-Histamine

- Ach

-Somatostatin (negative effect)
