digest system review Flashcards
what does pepsin in the stomach
digest proteins
food leaving the stomach is called
acid chyme
food leaving the stomach passed through
the cardiac sphincter
first part of small intestine is called
duodenum
protein + h20 > peptides (intestine) is what enzyme
trypsin
fat droplets + h20 > glycerol + 3 fatty acids
lipase
peptides + h20 > amino acids is what enzyme
peptidases
starch + h20 > maltose
pancreatic amylase
protein + h20 > peptides )in stomach) is what enzyme
pepsin
maltose+ h20 > glucose is what enzymes
maltose
what does gastrin do
increases secretory activity of gastric glands
what does sodium bicarbonate do
increases ph of chyme in duodenum
what does HCI do
kills bacteria and activates pepsin
what does cholecystokinin do
stimulates emptying of bile
what does secretin do
tells pancreas to produce pancreatic juices
what does mucus do
protects stomach walls from acid
what are the salivary gland called
parotid gland and sublingual and submundibular
what are the layers of the esophagus
serosa
smooth muscle
submucosa
mucosa
lumen
what is the epiglottis
tissue covers the opening of trachea
what does the soft patale do when swallowing
it closes off the nasopharynx
what are mircovilli
microscope extensions that cover villus
what is a lacteal
a small lymphatic capillary in villi
what is anaerobic bacteria
bacteria that grows without oxygen in the colon
how do you tell salivary amylase and pancreatic amylase apart
salivary is neutral
where is pepsin found and produced by
stomach and gastric glands
where is maltose made and found
small intestine
where is trypsin found and produced
small intestine and pancreas
where is pepidases found and produces
small intestines
where is nuclease found and produced
small intestine and made pancreas
nucleosides is found and produced by
small intestines
where is lipase found and produced
small intestine and pancreas
