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.
