All vital organs begin to lose some function as you age during adulthood. Aging changes occur in all of the body's cells, tissues, and organs, and these changes affect the functioning of all body systems. Living tissue is made up of cells. There are many different types of cells, but all have the same basic structure.

5. AGE RELATED BODY SYSTEMS CHANGES
Aging cells
• As cells age, they function less well. Eventually, old cells
must die, as a normal part of the body’s functioning.
Aging organs
• A decline in one organ’s function, whether due to a disorder
or to aging itself, can affect the function of another. For
example, if atherosclerosis narrows blood vessels to the
kidneys, the kidneys function less well because blood flow
to them is decreased.
