It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms and biosphere ([link]). Cells are made up of molecules. Two or more atoms combine to form a molecule, such as the water molecules, proteins, and sugars found in living things. Besides the cardiovascular system, the other organ systems of the body are the integumentary, skeletal, nervous, muscular, endocrine, respiratory, lymphatic, digestive, urinary, and reproductive systems. Higher levels of organization are built from lower levels. Figure 1.2.1 Levels of Structural Organization of the Human Body: The organization of the body often is discussed in terms of six distinct levels of increasing complexity, from the smallest chemical building blocks to a unique human organism. This is especially true in biology, as classifying and organizing the intrinsic attributes of living things is critical to understanding the world around us. Two or more atoms combine to form a molecule, such as the water molecules, proteins, and sugars found in living things. -Organs: structures that are composed of two or more different types of tissues. Assigning organs to organ systems can be imprecise since organs that belong to one system can also have functions integral to another system. The organization of the body often is discussed in terms of the distinct levels of increasing complexity, from the smallest chemical Some examples of cells at the cellular level of organization include: Cells are considered the basic units of life because they are self-sustaining. $$ Young, James A.
