What term describes reduced organ reserve and the inability to restore homeostasis after minor stressors in aging?

• A. Homeostasis
• B. Homeostenosis
• C. Senescence
• D. Gerotranscendence

Answer: (B)

The question is about the decline in the body's ability to keep internal conditions stable as we age, a loss of physiologic reserve that makes even small stressors harder to handle. This specific concept is homeostenosis: reduced organ reserve and a narrowing of the range within which homeostasis can be maintained after minor stress. With aging, multiple systems lose much of their reserve, so a slight illness, dehydration, heat, or a small medication change can push the body out of balance and lead to disproportionate dysfunction. Homeostasis describes the balanced state the body normally maintains, not the diminished capacity to restore it. Senescence refers to the aging of cells and tissues in a general sense, rather than specifically the reduced ability to cope with stress. Gerotranscendence is a psychosocial theory about spiritual and existential shifts in aging, not the physiological reserve concept.
