B Understanding the Rheopectic Properties of Blood: Fact or Fiction?

[Valentina Chianese]

Hello everyone, I need your help.

A teacher once told me that blood is a non-Newtonian, rheopectic, pseudo plastic fluid.
I get the non-Newtonian/pseudo plastic part, but I can't understand why blood is rheopectic...is it or not?
Thanks

rheopectic, pseudo plastic fluid.

Aren't those terms mutually exclusive?
You should look them up.

My understanding of physics is close to 0, I had serious problems with the pseudo plastic part alone so I'm not able to go further by myself...

What have you found with your Google searching? I found this pretty quickly, which seems to imply that blood is not but synovial fluids (lubrication in your body's joints) are:

Examples of rheopectic fluids include gypsum pastes and printer inks. In the body synovial fluid exhibits the extraordinary property of inverse thixotropy or rheopexy.[2]

Besides, what survival characteristic would be a reason for blood to have this property?

Yes I found that, it was the firts result. Also, I found absolutely nothing about blood being rheopectic, which seems to imply that it just isn't. And that's why I'm asking directly in this forum. I'm still doubtful because my comprehension of the subject is almost 0 so I have to rely on faith (faith on the absence of references about blood being rheopectic implying it isn't) or faith in the expert that told me it is. I hoped someone could explain to me in a simple manner why it is or why it isn't.

Maybe ask them for a reference?
