Overview
Chemistry is the science that deals with the structure of matter, and
the study of the human body begins with chemistry. It is essential for other
sci-ences, including physiology, pathology, pharma-cology, and microbiology.
Life is based on atomic, molecular, and chemical interactions. Each cell of the
body contains organelles made up of macro-molecules, and the cells then compose
tissues and organs. The chemical basics of life require the inter-actions of all
these components.
