Organs Of Allimentary Canal Flashcards
(23 cards)
Mouth
Takes in food digestion begins
Toungue
Muscular structure , contains organs of the taste + allows movement, facilitating the mixing of food w/ secretions from salvitory glands
Front palate
Hard palate bone
Food pushed up against to break down
Back palate
Soft palate assist in swallowing
Uvula
Hangs down from the soft palate
Teeth
Essential in grinding + chewing of food + mixing of secretions from salvitory glands
Salvitory glands
Produced salavia when Dali is mixed with food the chemical breakdown of food + nutrients begin
Paratid gland
Largest
Located near angles of jaw
Stems on duct
Viral disease when paranoid glands become inflamed
Mumps
Sublingual gland
Smallest gland under the younger
Ducts of rivinus
Submandibular gland
Under body of mandible
Wharton’s duct
Swallowing happens once food reaches
Pharynx
Involuntary reflex
___ & ___ fuse up to avoid food from entering nasal cavity
Soft palate + uvula
Extends from basil cavity to oral cavity serving as paging for air
Nasopharynx
Served as a passage wag for food + air
Oropharnyx
Lays on each side of oral cavity serving
Aids in fighting infection
Tonsils
Connects throat to larynx
Allows food to pass through esophagus + air pass through larynx to trachea
Laryngopharnyx
Flexible tube connecting pharynx to stomach
10”
Anterior to t/spine + posterior trachea
Esophagus or gullet
Esphohus wallas lined w/ mucosa + adjectives layers cobhaing muscle tissue produces :
Paristalsis causing food to move to stomach
Gravity also helps
NO DIGSSTION OCCURS HERE
Passed through diaphragm @ esphogeal hiatus
Aka LES Lower esophageal sphincter
Muscular ring band @ distal end of esophagus
Prevents stomach contents from coming back into esophagus
Cardiac sphincter
Diaphragm weakens + allows stomach to protrude up through esophageal hiatus
Hiatal hernia
Varricouse veins
Break open and bleed
Caused by exsessive drinking + heartburn
Constant bomiting
Esophogeal varices
