allow it to repair itself. As is obvious, this, like all other processes in the body,
is an extremely complex process in which millions of cells collaborate.
The locomotive capability of the skeleton is another important detail to con-
sider. With each step we take, the vertebrae making up our backbone move
over each other. This continuous movement and friction might normally cause
the vertebrae to wear out. In order to prevent this, between each vertebra,
resistant cartilages, called ‘disks’, are placed.
These disks function as shock absorbers. At
each step, a force is exerted by the ground on
the body as a reaction to the body’s weight.

These all show that the human body is the
outcome of perfect design, and it is a superior creation. This perfect design
helps a human being to make very dissimilar movements with great swiftness
and facility.
Just imagine if everything were not so perfect and the entire leg were
formed of a single long bone. Then, walking would be a serious problem and
we would have very clumsy and idle bodies. Even taking a seat would be dif-
