| Blood that
heals wounds
 You
must have observed that a slight skin wound stops bleeding
spontaneously after a little while. This, in fact, is
quite thought provoking since, under normal conditions,
a liquid flowing from a hole cannot possibly stop flowing
of its own accord. To have a better understanding of
this fact, suppose that you have a balloon filled with
water. If you make a little hole in this balloon using
a needle, water will leak out of the balloon. Will it
stop leaking after a while with no intervention of yours?
Of course not. All the water will keep leaking until
the balloon runs out of water. This applies to all liquids
in closed spaces.
|
Blood leaks through
the wound. |

Blood surrounding the
wound coagulates. |

Cells close up the wound like
a plug.
Blood moves through a closed circuit of
veins and leaks out in case of even a slight cut. However,
it is of great importance for our health to stop its
flow. You may have heard of people who die of excessive
blood loss in accidents or operations. Well then, what
causes blood to stop flowing a little while after a
wound starts to bleed?
| 
In the picture above, you can
see the red blood cells stuck among the fibers
of a blood clot. It is thanks to the clotting
ability of blood that it stops flowing soon after
you are injured.
|
This is called blood clotting, which is
one of the automatic security systems in our bodies.
Some substances existing in the blood stop and close
the wound. Thanks to the clotting ability of blood,
excessive bleeding is prevented. As shown in the illustration
on the right, some cells in the blood are informed of
the damaged vein and head for that site at once. First
they align themselves along the wound and obstruct the
flow of blood by weaving a web. This web stiffens in
time and forms what we call a scar.
Now let's think together. Can this planned
series of actions take place by chance? How is it that
some blood cells are informed of damage somewhere in
the blood vessels, which is like a gigantic world in
relation to their size? Why do they strive to prevent
the flow of blood? How do they know that they should
close the wound in order to stop loss of blood? Who
taught these cells that they should close the wound?
Cells could neither have learnt all these
things by chance nor could they have accomplished them
on their own. Even human beings, who have intelligence,
cannot possibly originate such a detailed system and
teach cells what to do. Certainly, the intelligence
demonstrated by these cells does not belong to them.
Allah inspires them and they act according to a perfect
plan.
Allah informs us of the excellence in
His creation as follows:
He created the seven heavens in layers.
You will not find any flaw in the creation of the All-Merciful.
Look again-do you see any gaps? Then look again and
again. Your sight will return to you dazzled and exhausted!
(Surat al-Mulk: 3-4)
A MIRACULOUS FLUID WITH NO REPRODUCIBLE
EQUALS: BLOOD
Scientists have conducted many studies
in order to produce a fluid similar to blood. However,
having failed to do so, they gave up trying to imitate
blood and focused on research in other fields.
Scientists cannot imitate blood because
blood samples withdrawn from a blood vessel clot at
once and the structure of the blood becomes unfit for
examination. It does not work to preserve the samples
in glass test tubes either, because blood cells do not
completely survive in tubes. Therefore, scientists had
to separate cells in the blood and examine them individually.
Undoubtedly, it is one of the most unreasonable and
illogical explanations in the world to claim that such
a perfect substance, which cannot even be imitated with
all the information human beings have gathered for years,
came into existence spontaneously and by chance. Allah
created blood as a matchless substance. A blood cell
that has many amazing abilities is merely one of the
manifestations of Allah's infinite wisdom in the human
body.
THE MOTOR OF THE BODY: THE HEART
Have
you ever thought how litres of blood circulate unceasingly
through our body up and down? Every object needs a motor
for continuous motion. Cars, aeroplanes, motorboats
and even your remote-controlled toy cars move by means
of motors. Likewise, blood circulating through our body
needs a motor too. The motor that propels our blood
night and day, for months and even for years is our
heart.
Place your fingers on your wrist and wait
for a while. You will feel the beating of your heart.
Your heart beats 70 times in a minute, and pumps some
152 million litres (40 million gallons) of blood throughout
your life. That much blood is an approximate equivalent
of the amount 10,000 oil tankers will hold. These figures
are astonishing, aren't they? Now suppose that you have
to bail a cup of water from one bucket to the other,
70 times a minute. In the end your arm and hand muscles
would ache and you would need to rest. However, your
heart carries out this task all throughout your life
and it never takes any rest.
THE MOST PERFECT
PUMP
| 
Your heart is an astonishingly
strong muscle. It beats about 70 times in a minute,
and pumps 59 cubic centimeters (3.6 cubic inches)
of blood at each beat. A heart which beats 2,500,000
times in 70 years pumps some 152,000,000 liters
(40 million gallons) of blood during this time.
That much blood is the approximate equivalent
of the amount pumped into the fuel tanks of 10
Boeing 747 jumbo jets every year.
|
The most perfectly structured pump in
the world is now beating on the left side of your chest.
With its marvellous design and unceasing contractions,
your heart makes the entire blood in your body complete
1,000 full cycles in a day.
The heart is a pump made of flesh, which
is approximately as big as one's fist. Nevertheless,
it is clearly the strongest, the most durable and the
most efficient engine in the world with respect to its
capacity. We have many reasons to express the strength
of the heart in this way. Most important, the heart
uses a great deal of energy when it beats. With the
energy used by the heart, blood can be raised up to
3 metres high. It may be helpful to give an example
in order to make it easier to comprehend the heart's
capacity. In an hour the heart can produce an amount
of energy that is enough to lift an average car approximately
one metre above the ground.

The fuel tank of a jumbo jet
will hold 217,000 liters (71,000 gallons) of fuel
when full.

Original Pumps in the Heart
The heart, which is a muscular organ of
about the size of one's fist, consists of two halves.
There are two pumps in these sections. The left pump,
which is stronger, drives oxygen-rich blood to all parts
of the body. The right pump is weaker than the former
and pumps oxygen-poor blood to the lungs. This transport
from the heart to the lungs is over a short distance
and is, therefore, called the "small circulation". The
former is called the "large circulation".
Each of these halves of the heart is divided
into two further sections. Blood between them passes
to the other section through heart valves. These pumps
operate unceasingly with a great amount of energy, thanks
to which blood circulates through our bodies 1,000 times
a day.
The Heart Maintains Itself
Machinery needs routine maintenance. It
may be necessary to maintain some machine parts or to
replace those that are worn out. Machines need to be
treated with oil after a certain period of operation,
so as to lessen wearing down by friction.
Like machinery, the heart, which keeps
operating all the time, requires maintenance too. However,
the heart carries out its maintenance itself; it lubricates
itself.
How do you think a heart lubricates itself?
The answer to this question is hidden in the creation
of the heart. The outer surface of heart is covered
by a sac consisting of two membranes. Between these
membranes is a greasy fluid. This fluid acts like motor
oil and facilitates easy operation of the heart. This
self-protective structure in the heart reveals once
again how perfect and complete is Allah's artistry in
creation.
