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.
WRONG WAY signs posted at one endabsent yellow linesvehicles all pointing in one directionAdded: Rectangular sign containing a white arrow on a black background pointing in the direction of the traffic flow, with the words ONE WAY in black type centered within the white arrow.Also: A white arrow painted on the street surface pointing in the direction of the traffic flow.
Valvs
Valves?
Capillaries
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.
No, blood flows in a closed circulatory system in the body, typically in a cyclical pattern. It is pumped by the heart through arteries, capillaries, and veins in a continuous loop. The direction of flow is determined by the pumping action of the heart and the structure of the blood vessels.
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.
The atrioventricular (AV) valve must be open to allow blood to flow from the atrium to the ventricle. This valve ensures one-way flow of blood by opening when the atrium contracts and closing to prevent backflow when the ventricle contracts.
forward
No the way the valves of the heart are set up causes the blood to move in one direction only.
