How do Trees Really lift Water to their Leaves?
« Reply #400 on: 18/09/2010 06:49:49 »
I was sitting on my porch watching the trees sway in a gentle wind and thought to myself "how do those trees get so much water up to their leaves.  Then it came to me as I thought that a tree isn't a static object like a rock.  It is constantly moving as it sways to and fro.  I thought to my school days and the venous return theory based on one way valves in the veins which squirt the blood up to the heart through movement of muscles, not pure pressure.  So it dawned on me, why can't trees use the same technique?  I love my porch.

Surely if gravitation is not a primary component of plant growth and implicitly of sap dynamics, then growing plants aboard the ISS would be easy, or - rather - even easier than on Mother Earth. However this obviously incompetent dude says it was more complicated than it seemed back home: newbielink:http://spaceflight.nasa.gov/station/crew/exp6/spacechronicles13.html [nonactive]

Interesting footage from BBC Frozen planet showing density flow in the Antarctic ocean.

Well worth viewing.

Thank you for the link and for your comment.

The swaying of branches and the movement of leaves could well play an important roll in the movement of sap. I have applied the density flow to the vascular and arterial systems and used it to great effect with Inclined Bed Therapy. Thanks for your comment.

Siphon in a vacuum proves atmospheric pressure irrelevant to siphon effect.

Radio Interview with Patrick Timpone on One Radio Network

20 years ago Andrew made a phenomenal discovery in circulation and how gravity acts upon fluid density changes that take place in all fluids where water is evaporated. In trees (Where this theory began) evaporation from the leaves alters the density of sap. In the body, the warm lungs and airways provide the same density changes in the blood and other fluids. It was not long before it became obvious that posture was incredibly more important than anyone could imagine. To make use of these density changes and allow them to assist the circulation all we needed to do was to manage our posture.
This was a Eureka moment of such magnitude it went off the scale for Andrew and instantly gave birth to Inclined Bed Therapy.
Show Highlights:
-Andrew explains how learning about how trees uptake water led him to understand the benefits of inclined bed therapy
