What is the correct way to file on shelves - right to left or left to right?

Yes, it is more likely a one or two chamber heart though.
add. Animals more primitive than and up to the Platyhelminthes, (flatworms) do not have blood supply and consequently have no need for a heart (pump). They just envelop their prey, often using a thick mucous to capture, digest and absorb their prey. Their digestive processes may be distributed over much of the body, and many lack a 'one way' digestive process.
They do have nephridia (primitive kidneys) of some sort, and of course reproductive processes. They have light and chemo receptors to detect their environment, but whether they have a true brain is open to argument. They certainly have connected nerves and may have a central nerve junction.
The next most developed worms are the Nemertine which have a blood supply, but not yet a heart, and have a one way digestive system. Their blood just sloshes round the blood vessels with movement of the animal. They have a brain, supplied with oxygen for its internal activity, and have well developed organ systems for specialized processing.
[It may well be that a true brain requires a blood supply for its internal activities.]
What keeps the valves from collapsing?
Valves are kept from collapsing primarily by the pressure of the fluids they contain, which exerts outward force against the valve walls. Additionally, structural design and materials used in valve construction provide inherent strength and rigidity, preventing deformation under stress. In many cases, external reinforcement or support mechanisms may also be employed to enhance stability and maintain the valve's shape.

How do you take contol away from the abuser safely?
There is absolutely no way to do this. An abuser needs to control the environment around them whenever possible because basically, they are frightened and that frightening feeling often comes out in violent ways. The abuser has grown up in an abusive environment. From all of this abuse they survive by putting up a wall and as soon as they are old enough to live on their own that wall is even stronger than ever and they won't let anyone break that wall down and that generally includes counselors of any sort. Abusers often lose jobs because of their tempers or generalized "bad attitude" towards boss' or coworkers. If they manage to keep a job, there are many things that can set them off as simple as even going home in rush hour traffic can put them in a lousy mood, simply because they can't control the outside world. Once home they know they can control their wife or children or girlfriend. Believe it or not most mental abusers hate themselves for what they do, but can't control it and have no idea why they feel this rage. Don't even try, because abusers usually will never think they are the cause of the problems, will not seek professional help, and as the years pass can get more violent. It's time for you to make some serious decisions in your relationship and consider moving on.
