describe journey of food
oral cavity-pharynx-epiglottis-stomach-duodenum-jejunum-ileum-caecum-ascending colum- transverse colum-desending colum-sigmoid colum- rectum-anus
1 of 18
describe mucosa layers- describe each
epitheal with glands, lamina propria with small blood vessles and bit of connective tissue, musularis externas as thin muscle layer
2 of 18
desribe submusocal layer
connective tissue and blood vessels. nerves as submucosal plexus in controlling secretion and contraction
3 of 18
describe muscularis externas layer
cicular and londituial muscle in peristalis, nerves as myenteric plexus. outisde as adventitia and or serosa. serosa only in peritonial cavity organs which have movement. retroperitonial dont move so have no serosa
4 of 18
what is epitheilum in oral cavity
stratfied squamous-protection
5 of 18
epitheium and structure in oesphagus
above diaphram- stratifired squamous, below- columnar epithelium. sphincter at bottom to prevent reflux
6 of 18
stomach adaptions
rugae folding for sa. gastric pits and glands for secretion
7 of 18
what glands in cardiac region
cardiac glands - secrete alkiline mucas
8 of 18
what glands in coprus
corpus fundic glands- 1. cheif cells- enzymes 2. pariteal- acid 3.muscoasl neck cells 4. endocrine- stimulates secretion
9 of 18
what glands in pyloric region
pyloric glands- endocrine glands
10 of 18
what are the small intestine adaptions
1.plicae (folds) 2. villi 3. mirocvillli 4. tubular glands and goblet cells
11 of 18
where in the SI does the pancreatic and bile ducts empty
duodenum
12 of 18
large intestines structure
smooth and lots of secretion cells
13 of 18
whats in pancreas, whats the difference
endocrine and exocrine glands. endo is blood system. exo is ducts
14 of 18
what 3 hormones secretes by endocrine in pancreas
insulin, glucagon and somatostatin
15 of 18
insulin details
produced by beta cells in islets of langerhans. uptake of glucose, synthesis of protiens, glycogen,fatty acids
16 of 18
glucagon details
produced by alpha cells, increases glucose levels in blood
17 of 18
somatostatin details
produced by delta cells, inhibits insulin and glucagon secretion
