The shrinkage of the thymus is especially striking and important in view of its role in immunological defense. The diminution of cellular tissue and replacement by fatty or connective tissue is prominent in bone marrow and skin. In the kidney, entire secretory structures (nephrons) are lost. The secretory cells of the pancreas, thyroid, and similar organs decrease in numbers.
Cell undergoes morphological and sub-cellular changes with aging.
Explanation:
With aging some cells becomes nodular or become more rigid. Accumulation of pigments and deleterious materials in and out of the cell. Lipofuscin gets accumulated in different parts of the body such as brain, eye and heart. Apart from this cell membrane also undergoes changes its permeability.
