A Perfect Machine



how can we understand what we are?
What are we made of? Are we aware
that all that we do—including reading


this blogger—is the work of a marvelous
machine? We know very little about how we
are able to be conscious of our own actions;
nevertheless, even though we are usually not
very aware of it, this community of organs
that is the body—an integrated system that
includes the brain, heart, lungs, liver, kidneys,
muscles, bones, skin, and endocrine glands—
acts together in exquisitely regulated
harmony. It is interesting that various
mechanisms work together to keep the
temperature of the body at 98.6° F (37° C);
thanks to the dynamic structure of bones
and cartilage, the body is maintained in
perfect balance. The body also has a
fantastic ability to transform the food it
ingests into living tissues, bones, and
teeth, all of which contribute to its growth.
By this same process, we obtain the energy
for working and playing. It is hard to
imagine that not long ago the cells of the
body of the person reading this book were
autonomous and were duplicating
themselves freely within the walls of a
mother's uterus. Certainly no one
reading this blogger could recognize herself
or himself in those cells. Nevertheless,
each cell carried within it the information
necessary for the development of that
person. Everything that happens inside us is
truly fascinating. Therefore, we invite you to
enjoy this blogger. It is full of incredible facts
