As blood circulates all through the body, it fulfills
many tasks. Now let's have a brief look at these tasks.
TRANSPORTING CARGO
We have already explained that all the
kinds of substances that our body
needs are conveyed to the con-
cerned organs by blood. In
the meantime, blood cells collect
waste matters, like carbon
dioxide, and make sure
that they are dis-
charged from
the body.
