What term describes the ability of interacting parts of a biological system to perform together and maintain function?

The term that best describes the ability of interacting parts of a biological system to perform together and maintain function is integration. Integration refers to the process by which various components or systems work collectively to achieve a common goal or function. In biological contexts, this involves the harmonious interplay of different cells, tissues, organs, or systems that cooperate to maintain homeostasis and overall organismal health.

For example, in the human body, the nervous system and endocrine system integrate signals to regulate processes like metabolism, growth, and response to stimuli. This collaborative functionality ensures that different parts of the organism are aligned and working effectively together. The concept of integration captures the essence of multiple systems functioning cohesively rather than just existing side by side.

While coordination is often associated with similar ideas, it typically emphasizes the organization of activities to achieve goal-directed movement rather than the comprehensive interconnectedness implied in integration. Interaction and collaboration suggest working together but do not fully encompass the systematic unity and purpose found in biological integration.
