Özet
Theories of ageing can be classified as error theories (stochastic theories) and programmed theories. This chapter discusses changes in organs and systems that occur due to the pathogenetic mechanisms identified in the theories of ageing. The systems covered include nervous system, cardiovascular system, endocrine system, gastrointestinal system, immune system, musculoskeletal system, and respiratory system. In previous decades, the ageing process was thought to be correlated with a decline in hormonal function throughout life. Studies were conducted involving the transplantation of animal endocrine glandular extracts into humans. Age-related changes in the urinary tract are mostly inevitable. Decreasing renal function is a challenging factor for the appropriate dosing of medications in the setting of multiple comorbidities. Physiologic changes in the urinary tract are discussed. The skin dermis loses its thickness with age.
