Organisation of the Cells into Tissues 🗸 Flashcards
salivary glands
parotid, submandibular, sublingual
straited ducts
Oesophagus to anal canal, four major layers
mucosa (three types)
submucosa
muscularis externa
serosa/adventitia
three layers of mucosa
endothelium -on basal lamina
lamina propria -loose connective tissue
muscularis mucosae -thin layer of smooth muscle
submuscosa
loose connective tissue
muscularis externa
2 thick layers of thick muscle (inner circular layer and outer longitudinal layer)
serosa
outer layer of connective tissue either suspends digestive tract or attaches to other organs
4 types of muscosa
protective
absorptive
secretory
protective and absorptive
ENS
Nervous system of the GI tract
Three Areas of the respiratory system
Bronchi
Bronchioles
Alveoli
Protective muscoa
non-keratinised stratified squamous epithelium
Where are protective mucosa cells found?
oral cavity
pharynx
Oesophageal
Anal canal
Absorptive mucosa
simple columnar epithelium with villi and tubular glands
small intestine
Secretory muscosa
simple columnar epithelium with extensive tubular glands
stomach
protective and absorptive mucosa
simple columnar epithelium with tubular glands
Large intestine
Liver lobules
Hepatic lobules are small divisions of the liver defined at the histological scale
