3. 
Humans use their
tongue to taste
different foods

See all those bumps?

Those are called
PAPILLAE and most of
them contain TASTE
BUDS.

Taste buds are
receptors that allow us
to experience the taste
of food.

4. SWEET
SALTY
SOUR
BITTER

5.  Umami
= Japanese word for “yummy”, such as
fish, cheese or tomatoes

6. A
person has about 10,000 taste
buds
 They
are replaced every 2 weeks
 As
we get older, taste buds don't
get replaced
 That's
why certain foods may
taste stronger to you than they do
to adults

7.  It
was thought that
our tongue has
different zones for
the four tastes.
 It
 In
is a MYTH!
fact, all taste
buds detect all
tastes.

8.  But
before you give
taste buds all the
credit for your
favorite food, it's
important to thank
your nose!!!
 Both
taste and smell
work together to help
us detect what food
are we eating.

9.  Inside
our nose we have
special cells called
olfactory receptors
 These
receptors help us
smell and they send a
message to our brain

10. 
While we are chewing, the
food releases chemicals that
immediately travel up into
our nose.

These chemicals trigger the
cells inside the nose and send
a message to our brain!

The brain will warn us about
what are we eating or
smelling!!

11.  Let’s
thank to our tongue and nose
for all the wonderful flavors that
we know…..
 Also
let’s thank them for protecting
us from the bad chemicals by
recognizing the bad flavors!!

12. THANK YOU!!
