One Direction
a valve that only lets things through in one direction.
A valve allows flow in only one direction. Diodes allow electrical current to flow in one direction only.
The aortic valve.
The most simple and practical design of a valve is a flap that keeps liquid from going into one direction, but allows it to freely flow in another direction. The name for this particular valve is called a check valve.
Check valve.
A check valve or one-way valve enables fluids to flow through in a single direction.
A valve that allows unrestricted flow in one direction, but fully impedes flow in the opposite direction. Used for backflow prevention purposes.
A check valve restricts the flow of a liquid or gas in a piping system to one direction.
Work is the product of force and distance, or w = F x d. Now, theoretically, if you push an object 100 yards to the east, and then turn it around and push it 100 yards back to the staring point, you did NO work, because distance has a vector component. But, if you just push it in one direction only, the work done will be the product of the force applied times the distance moved.
One directional valves keep blood in the heart flowing in the right direction. There are three valves: biscupid valve, semilunar valve and tricuspid valve. These open to let the blood flow through then close to prevent the blood flowing back in the wrong direction making the heart less efficient.
to keep blood flowing in one direction hope this helped you
