Organs Employed In Defence

spleen is a lump of meat just like all our other organs. Yet it displays a per-
formance and a degree of intelligence unexpected from a lump of meat. It
organizes everything, not allowing any problems to occur, and works
without rest. Indeed, the spleen works strenuously for the human from
the moment of his birth, and continues its function as long as Allah wills.

Cell Production

The bone marrow of the baby in the mother’s womb is not entirely
able to fulfill its function of producing blood cells. The bone marrow can
perform this function only after birth. Would the baby be anaemic in the
meantime?
No. At this stage, the spleen comes into play and takes control. Sens-
ing that the body needs red blood cells, thrombocytes, and granulocytes,

the spleen starts to produce these cells in addition to lymphocytes, which
is its main duty.
The spleen, however, is an unconscious lump of meat. It is not capa-
ble of assuming such a responsibility. Besides, even if it did, how would
it be equipped with the required information and components to produce
the extremely complex cells and proteins? Allah, Who created the human
body, created the spleen in such a way as to enable it to take on other re-
sponsibilities in addition its own task when necessary, and equipped it

with the necessary stimulus and production systems.

Phagocytosis
The spleen contains a large number of macrophages (cleaner cells).
These engulf and digest old and damaged red blood cells, some damaged
blood cells and some substances that are carried to the spleen through the
blood.

There is a very important chemical recycling system at work here.
The macrophage cells in the spleen convert the haemoglobin protein,
which is found in the composition of the red blood cells they have en-
