ome of the vital components of the blood are
proteins. Through the circulatory network
reaching all points in the body, proteins in
the blood have the means to reach every cell where they
are needed. For example, the protein hemoglobin carries
oxygen to the tissues, and the protein called transpherine
in the blood carries iron. Immunoglobins are proteins
that protect the body against bacteria and viruses.
Fibrinogen and thrombin cause the blood to clot. Insulin
is a variety of protein that regulates sugar metabolism in
the body. All of these essential proteins reach the tissues
by means of the bloodstream.
Albumin, one of the transport proteins in the blood,
attaches to fats such as cholesterol, hormones, poisonous
bile and drugs such as penicillin. Later, the blood moves
it through the body to the liver, where it deposits the tox-
ins it collects to be neutralized, and carries nutrients and
hormones to where they are needed. How can a molecule
like albumin, composed of atoms with no knowledge or
consciousness, distinguish between fats, toxins, drugs
and nutrients? Moreover, how is it able to deposit the
substances it carries in the liver, gall bladder and stom-
