Physiological functions refer to the processes and activities performed by living organisms to maintain life, encompassing everything from cellular metabolism to the operation of entire organ systems. These functions are regulated by complex biological mechanisms that ensure homeostasis, adaptation, and survival in varying environmental conditions.

Physiological Functions

Cellular metabolism comprises all chemical reactions within cells that enable them to maintain life, grow, reproduce, and respond to their environments. It is divided into catabolic pathways that break down molecules to release energy and anabolic pathways that build complex molecules from simpler ones.

Cellular Metabolism

Organ systems are complex networks of organs and tissues that work together to perform vital functions necessary for the survival and health of an organism. Each system has specialized roles but often interacts with other systems to maintain homeostasis and respond to environmental changes.

Organ Systems

Biological Mechanisms

Homeostasis is the physiological process by which biological systems maintain stability and equilibrium in response to changing external conditions. It is essential for the survival of organisms, enabling them to regulate internal environments such as temperature, pH, and ion concentrations to ensure optimal functioning.

Homeostasis

Adaptation is the process through which organisms or systems adjust to changes in their environment to improve survival and functioning. It involves both physical and behavioral changes that enhance the ability to cope with new conditions or challenges.

Adaptation

Survival refers to the ability of an organism or entity to continue living or existing, often despite challenging or life-threatening conditions. It involves adaptation, resourcefulness, and resilience, and is a fundamental aspect of both biological evolution and individual perseverance.

Survival

Environmental conditions refer to the various factors and influences that affect the living organisms and ecosystems within a particular area, including climate, soil, water, and biological elements. Understanding these conditions is crucial for assessing ecological health, planning sustainable development, and mitigating environmental impacts of human activities.
