The Cow’s Four Stomachs
A cow has four stomachs ! It may sound
unbelievable but it is true.
A cow do not have ordinary digestive system.
These animals do not have
Upper front teeth. They eat grass by wrapping
their tongue around it and pulling it from the
ground .They have back teeth but they cannot
chew the grass properly.
7. Fact and Opinion
Cow swallow grass without chewing up. When
it is swallowed, the grass
goes into the cow’s first stomach, called rumen.
In the rumen, the grass is broken up by some
digestive juices and forms into a ball. The ball of
grass is
called cud. The cow brings back the cud into its
mouth. Then the cow chews
the cud into a pulp with its back teeth and re-
swallows it.
After the cud is swallowed the second time,
it goes into the cow’s second stomach called
reticulum. The reticulum filters the food and
takes out
8. Fact and Opinion
Out small stones or any non-food matter. Then the
food goes into the cow’s third stomach called omasum.
The orsum further filters the food. Any undigested
food is sent back to the rumen. Then the cow chews it
some more. The digested food from the omasum
goes into the abomasum, the cow’s fourth stomach.
The digested food becomes a part of the cow’s body.

13. Fact and Opinion
Did you know that every drop of water makes a
journey? This journey is called the water cycle. When
water on the ground ( like in a puddle, lake or ocean )
is heated by the sun, the water changes into a gas,
called water vapor. The water vapor rises up into the
sky and then becomes part of a cloud. Wind carries the
cloud across the sky. Water droplets begin to fall from
the sky as rain, falling into puddles, lakes and oceans
on the ground.
___ Wind carries the water in clouds.
___ Water is heated by the sun and forms water vapor.
___ Raindrops fall from the sky.
___ Water vapor rises into the sky.
