Witrynaaging, progressive physiological changes in an organism that lead to senescence, or a decline of biological functions and of the organism’s ability to adapt to metabolic stress. Aging takes place in a cell, an organ, or the total organism with the passage of time. It is a process that goes on over the entire adult life span of any living thing. WitrynaCell membranes also change, and many tissues become less efficient in exchanging carbon dioxide and other wastes for oxygen and nutrients. Some tissues may become nodular or more rigid. An important age change is the accumulation of pigments and inert—possibly deleterious—materials within and between cells. The pigment …
