The heart is a one-way pump. By maintaining a pattern of certain chambers opening and closing, constricting and relaxing, the blood is pumped one way and one way only. There are also hundreds of one-way valves throughout the arterial system that keep backflow from occurring.
It is partly due to the way the heart pumps the blood and how it enters specific chambers of the heart at a time before being pumped out of the heart and around the body.
The left atrium has flaps that keep the blood flowing one way <3
The semi lunar valves. I have no idea why they are 'lunar' as that is usually to do with the moon, but they are
Left side of the heart.

energy flows in one direction and nutrients are recycled.
Yes. Electrical current only flows in a closed circuit. If it were an open circuit, there would be no current.AnswerAn interesting question. The answer is.... not necessarily! I say this because a capacitor is an open circuit, yet it allows d.c. current to flow for a short period of time (while it charges), and it allows a.c. current to flow continuously.
Its a structure attached to the gills of crustaceans like lobsters. it sort of beats, causing water to flow in and out of the gill chamber.
Decreased cerebral blood flow.

veins, they have valves, the reason why they have them is because blood flow is slow
It is to allow the blood to flow in one direction - towards the heart, it prevents back flow.
the pulmonary artery
Blood flow doesn't change direction. They always head for the same direction.
Diodes convert AC into DC by allowing current flow in one direction only. Since AC is alternating between plus and minus it is not possible to use a diode to allow AC to flow in one direction and not in the other direction.
forward
No the way the valves of the heart are set up causes the blood to move in one direction only.
