are studying chapter human nutrition and
that we are stdying topic role of
Gastrointestinal Hormones - a
Gastrointestinal Hormones will be
starting today about gastrin secretary C-
-CK more clean also hormones
 of gastrointestinal tract
now the hormones that are secreted by
gastrointestinal glands today we'll be
starting about them a little bit
the first hormone is gastrin now this
hormone gastrin is basically secreted by
a stomach
it's a polypeptide of 17 amino acids or
and it stimulates gastric acid and
gastric because secretion
now asGastrointestinal Hormones and
 Their Functions - Human Digestive System - Biology Class 11
 because an gastric
acid solutions are secreted further all
your enzyme whether it is carboxy
they're inspected a is trypsin pepsin
which will act on your carbohydrates
proteins are enhanced second inside C CK
now C CK enzyme is basically secreted by
your duodenum
remember duodenum jejunum ileum yes
dieudonné second-guesses and this
basically is used to digest fat
molecules of fat globules now it acts on
the pancreas and gallbladder and help in
the contraction of the glider to release
the by juices into small understand and
then the by juices can be further down
used next is secretary now if I talk
about secretary I could say that it
helps to neutralize the acid in this one
in this time where is your motive
now Morton has increased act within the
gastrointestinal tract and it's the only
hormone function this ligament are not
tilted
you
roll of gastrointestinal hormones first
gastrointestinal hormone is gastrin now
gastrin is basically secreted by the
stomach region now the sound region of
gastrin secreting is basically made up
of 17 or minor acids a dot n stands for
amino acid so basically a polypeptide or
protein consisting of 70 different amino
acids now basically it does the
stimulation of gastric acids or you can
see the stomach acids and gastric mucosa
is stimulated by secretion of gastric
CCK now CCC K is a hormone that's
secreted by duodenum and that's turue
know of the small intestine once that's
secreted it helps to digest the fat
molecules of my globules it basically
act on the pancreas and the guard of
reaching and help the contraction of the
gallbladder so that it can release by
juices and this by juices would be used
in the small intestine
security the next hole lunacy children
which is signaled by the essence and
other than security acts on the exo
current part of the pancreas and it
stimulates the secretion of water and
bicarbonate ions remember bicarbonate
ions which were used to remove carbon
dioxide to form the pancreatic juices it
also helps to neutralize the acid in
small intestinal acid or LCL was present
in the stomach region the next hormone
is gastric inhibitory peptide or GIP now
this is secreted by the small intestine
and this hormone precisely inhibits
gastric secretions and motility students
in this part of the chapter we came
across with few hormones of your
gastrointestinal tract and we did study
how they function and how actually they
work I have students V are now clear
that how this gastrointestinal hormones
function and work thank you
