Hello everybody,

I am an Austrian human physiologists looking for an answer to special
questions. Does anyone possibly know some specialist for circulation in
lower animals who could answer the following questions:

1 when in evolution valves where introduced in the circulation?

2 are there animals without valves and without peristaltic pumping and how
does the blood flow work in these cases?

The reason for this questions is, that we came across a physical principle
which would allow unidirectional flow in the circulation even without
valves. Our hypothesis is, that valves were introduced later in the
evolution, and this principle, not relying on valves, was first.

If you could forward this email to someone who could possibly add some
references, this would be really helpful.

Please send possible answers also to my personal adress, as I am not a
member of this list!!!

Thanks a lot in advance and best regards,

Max Moser
