## Emergence
**Emerges from:** [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [structure](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-structure.arrangement), [body](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-body.physical), [fluid](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-fluid.liquid), [motion](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-motion.movement), [work](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-work.effort), [mean](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-mean.signify), [means](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-means.method)

**Through:** the arrangement of physical matter enables rhythmic movement that moves fluid through a body

**Novel properties:**
- sustained directional flow
- rhythmic functionality
- internal circulation

## Examples
- The human heart beats approximately 100,000 times per day, pumping about 7,500 liters of blood. *(biology)*
- The Hoover Dam's pump-turbines cycle water to balance electrical grid demand across the southwestern U.S. *(engineering)*
- In 2003, the Northeast Blackout began with a software bug in Ohio that failed to signal grid stress. *(computing)*
