RESPIRATION

Respiration is based on delicate balances. Cold or polluted air we breathe
may effect our health negatively. For this reason, air should be warmed and
cleaned before inhalation. Our nose is created appropriately for this task. The
hair and nasal mucus on the walls of the nostrils filter air by capturing dust par-
ticles within it. Meanwhile, the air is warmed while travelling through the nos-
trils. The nasal bones are especially structured so that the air inhaled can go to
the lungs only after circulating several times in the nose and thus warming up.
The structure that enables air to travel several times within a tiny bone, can
only be the outcome of design. If human beings were to try to duplicate this
effect, directing the movement of air would only be possible by specific com-
plex calculations. The fact that this special structure exists to meet the needs of
another system - namely, cleaning and warming the air travelling to the lungs

- is evidence that both systems are specially created by the same Creator. After
all these stages, the air arrives in the respiratory tube after being moistened and
freed of dust.

SKELETON

The skeleton is an engineering marvel on its own. It is the structural sup-
port system of the body. It protects vital organs like brain, heart and lungs, and
upholds the internal organs. It furnishes the human body with a superior
capacity for movement that cannot be imitated by any artificial mechanism.
Bone tissue is not inorganic as many people think. Bone tissue is the mineral
bank of the body that includes many important minerals like calcium and phos-
phate. In accordance with the needs of the body, it either stores these miner-
als or delivers them to the body. Besides all these, bones also produce red
blood cells.

In addition to the uniformly perfect functioning of the skeleton, the bones
constituting it also have an exceptional structure. Having the tasks of bearing
