0 What Are We Made Of

What Are We Made Of

to understand the truest and
most elementary characteristics
of life, we must begin with the
cell-the tiny organizing
structure of life in all its forms.


 Most cells are too small to be
observed with the naked eye, but they
can be distinguished easily through an
ordinary microscope. Human body
tissues are groups of cells whose size

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
