Physiology involves studying functions in living systems influenced by the environment, with various approaches like mechanistic, evolutionary, and environmental. Organisms exchange substances with the environment to maintain homeostasis, utilizing strategies like avoidance, tolerance, and active regulation to deal with disturbances and fluctuations.
Insights
- Physiology encompasses the study of how living systems function and are influenced by their environment, including chemical, physical, and biological factors at different levels of organization.
- Homeostasis plays a crucial role in maintaining internal stability despite external fluctuations, with organisms employing strategies like avoidance, tolerance, and active regulation to respond to disturbances, while feedback mechanisms and proximate and ultimate causes further contribute to understanding physiological processes and adaptations.
