Shape of stomach
Major Portions of stomach
Surrounds superior opening of stomach
Rounded portion; superior and left of cardia
Inferior to fundus, large central portion
Connects stomach to duodenum
Greater curvature
Convex lateral border
Lesser curvature
Cancave medial border
Pyloric valve
(sphincter) Where stomach communicates w/small intestine at duodenum
Mucosa of stomach wall
Simple columnar epithelial cells
in stomach wall; large folds (inside)
Gastric pits
In stomach wall; openings that extend into lamina propria; caontain gastric glands
Gastric glands
occur at the bottom of gastric pits; each gland consists of 4 types of secreting cells
Chief cell
chief cell; inactive for of pepsin- pepsin + HCL= pepsin (enzyme that dig. protien)
Gastric lipase
Chief cell; splits fats in buttermilk; has limited role in adults
Parietal cells
Hydrochloric acid
Parietal cell; acts on pepsinogen to produce active enz. "pepsin"
Intrinsic factor
Needed for absorption of vitamin B12
Mucous cells
secrete mucous; also called mucous neck cells
Gastric juices
Consists of Chief(Zymogenic) cells, Parietal(oxyntic) cells, and Mucous cells
Enteroendocrine cells
(g cell); secrets hormones
Stomach gastrin
1. Stimulates growth of gastric cells
2. Secretes gastric juices
3. Increases stomach motility
4. Relaxes pyloric & iliocecal sphincters
5. Strengthen contraction of lower esophageal sphincter
Submucosa of stomach
Areolar conn. tissue
3 layers of muscularis in stomach
outer layer = longitudinal
middle layer = circular
inner layer = oblique
A soupy liquid resulting from mixing with digestive juices
Functions of stomach
1. Mixing waves
2. Storage
3. Digestion
Mixing waves
gentle rippling peristaltic movements
From interaction of pepsinogen and HCL; digests protein
Gastric lipase
Works on fat in buttermilk in infants, limited in adults, pancreatic lipase is esp. important in adults
