Document Summary
Body"s function is based on 4 macromolecules -> lipids, carbohydrates, proteins, and nucleic acids, thus aging can stem from changes in any/all of these macromolecules. Cell < tissue < organ < organ systems < organism < population. If either of these elements change, the cell"s specificity and function will change as well: organization of cell -> plasma membrane, cytoplasm, and nucleus. Example: heart cells have different glycoproteins from liver cells which confers specificity for that tissue type: all cells of a particular individual may carry several identical glycoproteins. Act as individual tags (i am self; i am safe) and function/location tags. Can lose autoimmune system if they don"t have self-recognition (immune system cells. Indicate to immune system not to attack will start attacking self-cells: can be systemic (whole body) or individual organ (ex: lupus) Cytoplasm -> fluid within the cell that supports organelles.
