The human body is a complex connection of various systems, each affected
by the internal and external environment. Each system relies on the other and changes
in one can result in variations in all other organ systems. As humans age, their physical
appearance changes, but the aging process also occurs below the skin. Each organ
system is impacted by time, and an individual’s lifestyle can greatly impact his/her
organ system. Various anatomical and physiological alterations that occur to the major
organ systems due to aging and are relevant to an anesthesiologist are discussed below.
