The Signs of Allah
When I went to school that morning,
everyone was
talking about the accident.One
of the boys in the class.Abmad.had suffocated.One of the boys asked the teacher:
Why did
Ahmad's hands and face turn blue,
and what is meant
by suffocation?"
The teacher thought for a moment
and then said:
Since you all want to know the
answers to these questions,
we would better begin with our
lesson on blood
circulation and respiration.I
suggest we begin it tomorrow.But I will need your help; who
is ready to bring
to the class the heart and lungs
of a sheep?"
Two of the boys promised to bring
them, and the
next day everything was set for
the lesson.First, the
teacher dissected the heart with
a sharp knife.and
showed its different sections to
the class, explaining
each of their functions.Then he
did the same with the
lungs.By this time we were all
aware of the importance
of the heart and lungs, and we
knew the answers to
our former questions.Then the
teacher handed out
copies of the following summary
which he had written
on the same subject.
Blood Circulation and the Respiratory
Systems
In this lesson you will learn some
of the secrets of
your body.and you will understand
further the harmony
and symmetry of the parts and systems
of the
body.You will also realize that
the body itself is one
of the signs of Allah's power and
wisdom and so you
will learn more about Allah.You all know that the blood in
our bodies is constantly
circulating, but do you know what
purpose this
"blood circulation" serves? Just
like a stream or a
river, blood flows to each and
every cell of the body.and it brings it food and oxygen.Oxygen is very crucial for life.If the cells of the
body do not receive oxygen constantly.we would
immediately (lie because it is
oxygen that maintains our
body's heat and energy.Oxygen is circulated in the body
by the red blood
cells.These cells swim in the
bloodstream.Of course.blood cannot circulate in the body
just by itself.This
is accomplished by a very strong
pump, and this pump
works regularly to push the blood
throughout the whole
of the body.Can you guess its
name?
Yes, the name of this pump is the
heart.With each beat of the heart, the
red blood cells with
their oxygen enter the largest
of the body's arteries.This artery divides into different
branches, and each.of these branches in turn divides
into other, narrower
branches.The narrowest of these
branches are called
the capillaries.When the blood is flowing through
the arteries, we
call it arterial blood, and this
blood flows to the tissue
cells of the body.There it does
two things.Firstly, it
gives the tissue cells the oxygen
it is carrying, and this
keeps the cells alive.Secondly,
it takes away from the
tissue cells carbon dioxide, which
is a poisonous gas.This gas makes the blood cells
dark and dull, and if
they were to remain like this they
(blood cells) would
die, and then we would die too.In order to remain alive, the blood
cells need oxygen.First, they must return to the
heart, and for this they
must travel along different passages,
for they cannot
return through the arteries.Our
wonderful Creator
foresaw this need and provided
our bodies with another
kind of channel called veins.The
blood passes through
these veins with its poisonous
gas, until it reaches the
heart.Amazingly, He created tiny
valves so that the
blood in the veins, does not mix
with the blood in the
arteries.When the blood reaches the heart,
it must not mix
with the fresh blood to be pumped
into the arteries.Therefore, Allah has created a
kind of thick, strong
wall in the heart to keep the two
types of blood apart.This "wall" is called the septum'.But, of course, there is no oxygen
in the heart, and
the tired and used blood that carries
only gas must still
make its way to the lungs.Where
the blood is revived
by the oxygen in the air we breathe.With one powerful beat, the heart
sends the used
venous blood from the heart to
the lungs.There, they
take the oxygen they need from
the air and release the
carbon dioxide which is expelled
from the body by the
lungs.This is what happens when
we breathe out.This symmetrical system of blood
circulation and
respiration has obviously come
into existence according
to a pre-arranged and well-thought
out plan.The
design of this system is so intricate
and precise that it
cannot, by any means, come into
being all by itself
and at random.Matter by itself
has no intelligence to
design such complex and intricate
structures.There
fore, who-other than Allah-could
have created such
a beautiful system?
In this way, when we study systems
like the respiration
and blood circulation.we are struck
by their perfect
symmetry and harmony, and we come
to realize
that all of this is a sign of the
greatness of our Creator.We become more aware of His countless
blessings.We know Him better; we worship
Him more sincerely:
and we are always ready to praise
Him and serve Him.
