SMELL
HOW DOES IT WORK?

Your sense of smell is an amazing thing.
Molecules enter your nose from air and go to
receptor neurons. Small hairs called cilia capture
the molecules and identify them.
WHY DO WE HAVE THIS SENSE?
The sense of smell is very useful to daily bases. It
helps us taste and can warn us of danger like
when there’s smoke or poison, it can also helps us
in survival.
 Its also fun to have!

TOUCH
HOW DOES IT WORK?

It works by sending information to the spinal
cord then goes to the brain. The sense of touch is
located in the dermis part of the skin and is
found everywhere on your body.
WHY DO WE HAVE THIS SENSE?
The sense of touch is one of the important. It’s
the only sense that is all over your body and not
just a specific part. You use it for working, feeling
and everything else.
 And when your about touch something, the brain
tell you not because it hot. (Just an example)
Your brain controls the sense of touch.

TASTE

When you eat, or drink something, your taste
buds begin to work. They relay information about
the drink, or food to transmit to your brain. Taste
buds are the bumps on your tongue.

then boys.
