Digestive System Flashcards
Liver gall bladder pancrease salivary glands
Accessory organs
Digestive track mouth to anus
Alimentary canal
Inner most layer or alimentary canal secrete mucous and enzymes
Mucosa
Blood vessels lymph and nervers alimentary canal
Submucosa
2 layers of muscles (circular and longitudinal) that pushs food
Muscularis externa
Outmost layer reduces friction
Serosa
Wave like contractions that push food down the digestive tract
Peristalsis
What cells control peristalsis
Pace setter cells
Area from diaphram to pelvis
Abdominal cavity
Tissue covering internal organs in the belly
Visceral peritoneum
Tissue on the wall of the belly
Parietal peritoneum
Lubricates cavities to reduce friction
Peritoneal fluid
Tissue that holds the small intestines in place
Messenteries
Connects stomach to back of the peritoneum
Lesser omentum
Runs from the base to back of peritoneum
Greater omentum
Connects large intestine to parietal peritoneum
Mesocolon
Area behind the peritoneum where kidneys are
Retroperitoneal
Lining of the mouth
Oral mucosa
Lips
Labia
Between cheaks and gum
Vestibule
Gums
Gingivae
Roof of mouth (front and back)
Hard and soft palate
Excess tissue in back of the throat
Uvula
Lymphatic tissue back of the throat
Tonsils
Taste buds
Lingual papillae
Tissue under tounge
Frenulum
Tounge tied
Ankyloglassia
Enzyme that starts to break down fats
Lingual lipase
Small cordon are shapes and helps with speech
Intrinsic
Larger used for major movements
Extrinsic
Found in cheaks - salivary glands
Parotid
Found under the younger- salivary glands
Sublingual
Found in lower jaw
Submandibular
Increase saliva release relaxed
Parasympathetic
Decreases saliva release
Symphetic
Can control swollowing food
Somatic system
Process of chewing
Mastication
Main compenent of teeth
Dentin
Center of tooth contains blood vessels and nerve
Pulp cavity
Narrow tunnel that blood vessels and nerves run through
Root canal
Base of the tooth
root
Connect teeth to jaw bones
Periodontal ligament
Connects tooth to gym
Cementum
Viewable part of the tooth
Crown
Infection of the gum line
Gingivitis
Covering of the tooth
Enamel
Front teeth cute
Incisors 8
Canaries tear
Cuspids 4
Premolars grind
Bucuspids 8
Grind 16
Molars
Baby teeth
Primary 20
Adult
Secondary 32
Cavities
Canaries
Common pathway for air water and foot
Pharynx
Above soft pallet
Nasopharynx
In mouth
Oral pharynx
Past epiglotis
Larynopharynx
Tube that connects the mouth to the stomache
Esophagus
Deglutuition
Swollowing
Tounge goes up soft palate up
Buccal phase
Bolus stimulates swollowing reflex
Pharyngeal phase
Food enters the esophagus
Esophageal phase
Material that leaves stomach
Chyme
By esophasase
Cardiac
Over flow area for food
Fundus
Digestion occurs
Body
Where foot leaves the doedenum
Pyloric
Digests fats
Lipase
Digest protiens
Proteolytic enzymes
Digestive starchs
Alpha amylase
Liver cells take out pathogens
Kuffer cells
Liver cells that adjust level of nutrients
Hepatocytes
Activates smells taste cause release of salvia
Cephalic
Stomach stretches
Gastric
Controls rate the stomach empties
Intentional
Make hcl
Parietal cell
Creat pepsinogen
Chief cells
Real eases bile and pancreatic enzymes
CCK
Activates stomach acids and enzymes
Gastrin
Fiala yes blood vessels in intestine slow acid release make buffers
VIP
Creates mucous
Enterokinin
Releases insulin slows stomach activity
GIP
