Examples of APCs are macrophages. They do this by taking the foreign mate-
rial into a cavity in their cytoplasm - the part of the cell outside the nucleus -
and adding digestive chemicals to them. These chemicals break the bacteria
into fragments of the proteins from which they are made, fragments that are
now harmless, but which can also be utilized.

means that the APC is even aware that the T cell will extract the required
information from this sequence.
At this point, it would be useful to recall one thing: We mentioned
actions such as "knowing", "calculating", "thinking", "serving". Unques-
tionably, those actions require a certain consciousness. It is virtually im-
possible for a being with no consciousness or will to perform these ac-
tions. Yet, here we are talking about these abilities as being inherent in
these minuscule entities: common, tiny, unconscious cells. Therefore, who
gives this consciousness, ability, and a glorious system to these cells?
The answer to this question is very evident. It is Allah Who creates
the APC and the T cell, as well as all other cells in the body, in a harmoni-
ous way to serve in the same system.
