Document Summary

The structural organization of the human body: simplest level of structural hierarchy is chemical level, here, atoms combine to form molecules, (ex. water and proteins) which then form organelles. Atom: smallest particle of an element with all of the properties of that element. Molecule: the smallest amount of a substance that can exist alone = a combination of atoms. Organelle: molecules associate in specific ways to form organelles = basic components of living cells give 5 examples of organelles. Nucleus, mitochondrion, chloroplast, golgi apparatus, lysosome, and endoplasmic reticulum. Cell: fundamental structural & functional unit of a living thing; cells vary widely in size. & shape, reflecting unique functions in the body: in complex organisms (humans), hierarchy continues to tissue, organ and organ system level. Tissue: groups of similar cells that have a common function. Organ: structure composed of at least 2 (but usually 4) tissue types that performs a specific function for the body.
