are studing chapter human nutrition in
that we are studying topic function of
Stomatch we all know that stomach is a
place which is made up of muscular walls
and that can store your food
so our storing your food what are the
other functions of stomach today we'll
be studying and looking to teeth.
Stomatch this is the place been food from
your buccal cavity then your Oesophagus
cavity finally reaches inside stomach
now stomach is basically a muscular bag
or muscular voice whenever you eat food
your stomach contracts or relax
depending upon your food material that
you want eaten or the quantity that they
have eaten so we can say that stomach is
nothing but a reservoir for food
material keeping when I say there's a
way you can say a ban just to keep your
food material stomach basically release
enzymes gastric enzymes which are called
as pepsin trypsin pepsinogen all such
enzymes are released by stomach and this
has ents helps to break down food apart
from that stomach has a bag of HCL ended
so in case of bacteria in weights inside
your body this X here which is a greater
ph or you can say a good quality ph
helps to kill those bacteria inside
stomach apart from that stomach release
is an enzyme which is call effect signal
chain now this pepsinogen will isolate
will break down protein but it cannot
act on it itself so pepsinogen
is acted upon by Xen and now in the
presence of HCl pepsinogen
is converted into pet cell which is a
workable form of an enzyme
now this pets in action proteins which
you eat and Bridgetown them into pro
pierces or efectos that of the mucous
layer of your summer
helps in proper digestion or breakdown
of the food that is the mechanical
breakdown
because we all know the physical
breakdown is done inside your mouth the
gastric glands secrete enzymes
functions of summer now stomach
basically acts as a reservoir for food
material the mucosal layer of stomach
basically has gastric clan the ashtag
line basically secretes enzyme along
with that gastric glands secrete certain
other things status mucosal next cells
of gastric glands secrete mucus and this
reduces the acidity in the stomach
remember that said at co-president
stomach so just to reduce that acidity
mucus si importance apart from that
peptic of chief cells secrete an enzyme
which is called as pepsinogen that will
help to break down trophy
pepsinogen or you can say HCL secrets
pepsin and now this steps in plus
proteins in the presence of HCL form
spec tones or proteins and your HCl is
secreted by parietal cells or oxytocin
cells students in this part of the
chapter we have studied about the
function of stomach and how stomach
helps to digest fill and various other
functions I hope you are clear about
this concept thank you
