What are the two main parts of the GI tract - ANS-Alimentary tube and the accessory organs
What does the alimentary canal protect against - ANS-Corrosive materials (stomach)
Infections
Mechanism stressors (abrasions)
6 processes of the digestive system - ANS-Ingestion
Secretion
Mixing, propulsion (voluntary, swallowing) (involuntary, peristalsis)

Mastication - ANS-Chewing, swallowing
Where does absorption take place - ANS-Small intestine
What do carbs, proteins, and lipids breakdown into - ANS-Proteins- amino acids
Lipids- glycerols and fatty acids
Enzymes - Carbs- simple sugars
simple squamous cells - ANS-Permeable- Found where filtration and diffusion occurs
capillaries, alveoli, glomeruli
stratified squamous epithelium - ANS-occurs in places of high abrasion.
mouth (reason for fast healing), esophagus, vagina
,simple cuboidal epithelium - ANS-Mostly for protection, may be active or passive
Kidney tubules, ovaries, thyroid gland, and glandular ducts
stratified cuboidal epithelium - ANS-Protect the ducts and glands
sweat glands, mammary glands, cicumanal glands, and salivary glands
Columnar pseudostratified epithelium - ANS-1 layer of cells that appeared stratified throughout

*If it is rigid and fixed, it will be covered by adventitia (loose connective tissue)
4 anatomical features not covered by serosa - ANS-Esophagus, pharynx, rectum, and oral
cavity
*If it is part of the GI tract and free to move, it will be covered by serosa
*If it is rigid and fixed, it will be covered by adventitia (loose connective tissue)
Accessory organs of the GI tract - ANS-Compliment digestive system
Teeth
Tongue
Salivary glands
Liver
Gallbladder
Pancreas
Three salivary glands - ANS-Sublingual
Submaxilary/submandibular
Parotid
Two Enzymes in saliva - ANS-Salivary amylase

Parotid gland - ANS-Releases amylase- breaks down complex carbohydrates
Largest of the salivary glands- 25% of saliva
Sublingual glands - ANS-Front and bottom of the mouth, under the tongue
