DIGESTIVE Flashcards
what do you call the organ where major digestion occurs
small intestine
this is the breakdown of ingested food
Digestion
these are the constructive & degradative cellular activities within the body
Metabolism
Metabolism is the production of?
cellular energy or (ATP)
Two main groups of the Digestive system
Alimentary Canal
Accessory digestive organs
what is the continuos coiled hollowed in the body
Alimentary canal
Organs of the alimentary canal
Mouth
pharynx
esophagus
stomach
Small & large int
Anus
what muscle in the mouth allows whistling, swallowing and blowing
buccinator muscle
this organ protects the anterior opening in the mouth
Lips (Labia)
this is part of the oral cavity that form the lateral walls
Cheeks
what part of the oral cavity that forms the anterior roof and separate oral cavity to breathe through nose
Hard palate
this is the fleshy projection of the soft palate
Uvula
the uvula closes the ___ when you swallow
Nasopharynx
this part of the mouth has salivary glands to produce mucus to keep lips and cheeks moist
Vestibule
what is the space between the lips externally and teeth/gums internally
Vestibule
this part of the mouth is attached to hyoid & styloid
Tongue
prevents pathogens enter oral cavity
palatine tonsil
Processes of the mouth
Mastification
mixing masticated food w saliva
initiation of swallowing by tongue
allow a sense of taste
this is called the chewing of food
Mastification
how many muscles does the tongue have
8
smell contribute how much percent of taste
80-90%
allow airflow between nose and mouth
nasopharynx
where food and air in the oral cavity
Oropharynx
what part of pharynx is not part of digestive system
nasopharynx
location of oropharynx:
posterior to oral cavity
which pharynx is connected to esophagus
Laryngopharynx
this is the food movement via muscle contraction
peristalsis
what part of the stomach where food enters?
cardio esophageal sphincter
they insulate cushion abdominal organs
omentum
this is the storage tank and site for food breakdown
stomach
this is the specialized mucosa in the stomach
simple columnar epithelium
they produce sticky alkaline mucus
mucous neck cells
they secret gastric juice
Gastric glands
they produce pepsinogens or protein digesting enzymes
Chief cells
they produce hydrochloric acid
Parietal cells
they produce gastrin
Endocrine cells
chief cells need what to active inactive enzymes like pepsinogens
hydrochloric acids
it makes 40% of the small intestine
jejunum
this part of the small intestine for absorption with tons of microvili
jejunum
absorbs vitamin B12
ileum
this part of the intestine curves around head of pancrea
Duodenum
these are the source of enzymes mixed with chyme
intestinal cells
pancreas
where does bile enter from?
gall bladder
absorb fatty acids
Lacteals
what ae the structures involved in absorption of nutrients?
absorptive cells
blood capillaries
lacteals
patches that has lymphoid and immune for intestinal bacteria
peyers patches
this organ frames the internal abdomen and plays a role in absorption of water
large intestine
large intestine plays a role in digestion. t/f
False
pouches of the colon wall
Haustra
accessory digestive glands
SALIVARY GLANDS
Pancreas
Liver
Gallbladder
3 salivary glands
parotid gland
sublingual
submandibular
largest salivary gland
parotid gland
pancreatic enzymes
amylase
lipase
protease
second largest organ in our body
Liver
emulsify fat
bile
imbalance of bile
