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

AI Thread Summary
Blood is primarily classified as a non-Newtonian fluid, specifically a pseudoplastic fluid, rather than rheopectic. The discussion highlights confusion over the terms, with participants noting that blood does not exhibit the properties of rheopecty, which are more characteristic of fluids like synovial fluid. A lack of credible references supporting the claim that blood is rheopectic further suggests it is not. Participants encourage seeking clarification from the original source of the information. Overall, the consensus leans towards blood being non-rheopectic based on available evidence.

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:

https://en.wikipedia.org/wiki/Rheopecty
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?
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Free fall of person in a sled to direct horizontal motion by atmospheric resistance'

Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
