In Health, Illness, and Optimal Aging: Biological and Psychosocial Perspectives, Carolyn M. Aldwin and Diane F. Gilmer undertake the challenging task of assembling an objective and holistic picture of human aging. The authors provide comprehensive, multidisciplinary coverage of the physical aspects of aging, including age-related changes and disease-related processes, the demography of the aging population, theories of aging, and the promotion of optimal aging. In addition, the book covers the psychosocial aspects of aging, including mental health, stress and coping, spirituality, and care giving in later years. Health, Illness and Optimal Aging is recommended for researchers seeking an overview of health psychology and aging, as well as undergraduate and graduate students taking classes in the social, behavioral, and health sciences. This text is also valuable for practitioners working with the elderly in fields such as nursing, social work, occupational and physical therapy, day-care and nursing home administration, psychology, and rehabilitation.
Chapter 6: Aging of the Internal Organ Systems
Aging of the Internal Organ Systems
This chapter discusses aging of the cardiovascular, respiratory, gastrointestinal, and renal/urinary systems. These systems are extraordinarily complex, and we provide only a brief overview of the basic anatomy and physiology of each system. We focus on describing normative age-related changes (i.e., changes common enough that most older adults can expect to experience them) and discuss the common diseases and malfunctions of the individual systems that can accelerate the aging process. A section follows on how to delay or slow aging in each of the systems.
