Which of the following indicates normal functioning of all body systems?

The term that indicates normal functioning of all body systems is homeostasis. Homeostasis refers to the ability of living organisms to maintain stable internal conditions despite changes in external environments. This includes regulation of factors such as temperature, pH, hydration, and electrolyte balance, enabling the body systems to operate effectively and efficiently. When homeostasis is achieved, all body systems are balanced and functioning optimally, which contributes to an individual's overall health.

The other terms relate to health but in different contexts. Pathogenesis refers to the development of disease and the biological mechanism that leads to a pathological state. Symptomology involves the study of symptoms that are indicative of a disease or condition. Diagnosis is the process of identifying a disease or condition based on the signs and symptoms presented. While all these aspects are crucial to understanding health, only homeostasis specifically addresses the normal functioning and balance of all body systems.
