There are four tissue types in the body. For example, without organization, it is nearly impossible for researchers or clinicians to study the chemical and cellular effects of specific diseases in a population. Cells require oxygen to make energy. Physiology. For instance, the heart and blood vessels work together and circulate blood throughout the body to provide oxygen and nutrients to cells. To study the smallest level of organization, scientists consider the simplest building blocks of matter: atoms and molecules. The respiratory system is responsible for the exchange of oxygen and carbon dioxide through breathing. In going from the chemical to the systems level, it is important to keep in mind, that the body is composed of cells that come together to form tissues, which in turn form organs. How is the human body organized? It is important to note that even more complex schemas, or organizational hierarchies, that exist in biology. Atoms are organized into molecules, and molecules are organized into cells, the basic units of life, which make up the organization of the human body.
