Cortez Janessa, Digest
Major functions of the digestive system
mechanical digestion
physical breakdown of food by cutting and grinding
chemical digestion
requires enzymes
taking in food through the mouth
breakdown of food into molecules
absorbs and transports of digested end product into blood and lymph
defecation of elimination pf indigestible substances from the body
GI Tract
Submucosa
containing major blood vessel
many elastic fibers to retain shape
Mucosa
produces mucus for reduction of frinction and potections
epithelium
muscular layer
inner layer squeezes and decrease the size of the lumen
external anal sphincter is skeletal muscle
Serosa
outer covering of the GI tract
composed of thin layer of areloar connective tissue
major organs of the digestive system
Stomach
food empties into duodenum of small intestine and food enters at the cardioesophageal
esophagus
food transports by peristalsis, no digestive function only passage for food
small intestine
mixes food with digestive juices from the pancreas liver
large intestine
waste products from the digestive process and includes part of food, fluid, and older cells
liver
regulates most chemical levels in the blood and excretes a product called bile
Pancreas
makes enzymes and which break down sugars, fats and starches
gallbladder
it stores bile intil its needed foor digestion
rectum
recieve stool from the colon and the be ready to poop put
salivary glands
makes saliva and helps with swallowing and protecting your teeth from bacteria
locations of the digestion
gall bladder
on the right side of your abdomen
small intestine
located within the gastrointestinal tract
large intestine
wraps around the border of the abdominal body cavity right side
stomach
left side of the upper abdomen
liver
upper right hand in the abdominal cavity
located at the end of the large intestine
salivary glands
located in the mouth
esophagus
lies behind the trachea and in front of the spine
pancreas
behind the stomach in the upper left abdomen
rectum
located in the end of the large intestine
digestive enzymes
pancreas
converts food we eat into fuel for body cells
exocrine function helps in digestion
endocrine function helps regulates blood sugar
peristalis and segmental movemenet mix chyme with digestive enzymes
solid organs of the digestive system
enzymes break down sugars and fats
makes hormones
disorders of the digestive system
goblet cells
produce mucus
cheif cells
produce pesinogen
parietal cells
produces HCI and intrinsic factor
