System Integration: Coordinated Subsystems Keep an Organism Alive

Definition

System integration

System integration is the coordination of interdependent subsystems to work together in a coordinated manner to achieve a specific overall function.

Living systems at every level depend on system integration to survive.
Integration means the coordination of separate components so they perform an overall function together.
Without integration, individual parts cannot work efficiently and the organism fails.

Analogy

Picture a cheetah sprinting across the savannah.
Its muscles contract, its lungs take in oxygen, and its heart pumps faster all at once.
That seamless teamwork between body systems is system integration.

How Integration Is Achieved: Signalling and Transport

Components integrate by exchanging signals and materials.
1. Nervous signalling: fast electrical impulses carry information between cells.
