TRANSCRIPT OF AUDIO
From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of September 6, 2021. This revised episode from October 2017 is part of a series this fall of episodes on water connections to the human body and human biology.
SOUND - ~3
How is a human heartbeat part of a water story? Have a listen for about 25 seconds to the following mystery sounds, and see if you can guess the heart-and-water connections they represent. And here’s a hint: if you have the energy, you could follow many branches to this solution.
SOUNDS - ~21 sec
You’ve been listening to sounds from a platelets donation at the American Red Cross’ New River Valley Donor Center in Blacksburg, Virginia. The sounds—a blood-pressure measurement, a needle stick into an arm vein, and the machine separating blood components and recirculating fluid to the patient—illustrate three connections between the human circulatory system and water.
First, the heart provides a force—measured by blood pressure—to keep blood circulating around the body, like the sun’s energy powers evaporation and winds that help keep water circulating around the earth. Second, arm veins are part of an intricately branched system of arteries, veins, and capillaries, resembling a watershed’s branching pattern as one travels uphill from ocean to river to headwater streams. Humans have an estimated 60,000 to 100,000 miles of blood vessels, compared to Virginia’s approximately 100,000 miles of rivers and streams. Finally, blood’s components are mostly water: blood plasma is a solution of water and many biochemicals, mixed with water-based red and white blood cells and with platelets. As a result, blood in the human system has water’s physical and chemical properties for transporting materials and regulating heat.
Cells and transported substances make blood “thicker” than water, just as the saying goes. But the water we borrow temporarily from the global water cycle is at the chemical and physical heart of blood and the circulatory system’s vital functions.
Thanks to staff at the New River Valley Donor Center for participating in this episode, and thanks to Soundbible.com for the heartbeat sound.
We close with some music inspired by the action of the human
heart. Here’s about 20 seconds of
“Heartbeat,” by the Harrisonburg and Rockingham County, Va.-based band, The
MUSIC - ~23 sec –Lyrics - “Feel my heartbeat comin’ in next to you; heartbeat, yes you do.”
Virginia Water Radio is produced by the Virginia Water Resources Research Center, part of Virginia Tech’s College of Natural Resources and Environment.

Thanks to Ben Cosgrove for his version of “Shenandoah” to open and close the show. In Blacksburg, I’m Alan Raflo, thanking you for listening, and wishing you health, wisdom, and good water.
