SUMMARY
The human heart functions as a positive displacement pump rather than a centrifuge pump due to its mechanism of blood flow, which occurs in discrete packets rather than a continuous stream. This characteristic results in the audible heartbeat, distinguishing it from centrifugal pumps that maintain a steady flow. The discussion highlights the evolutionary challenges of developing a strictly rotating organ, noting that such adaptations are rare in the animal kingdom.
