because your arteries are being pumped on a same vessal. if you were to lay out all off those vessels, you would see its all one beg flow of blood.
no. it depends on the type of blood vessel.
if we say about arteries then flow is downward but if we say about veins then flow is upward.
blood flows in one direc tion as heart pumps the blood
A diode is one of the fundamental building blocks of electronics. They allow the flow of electrons in one direction only. Thus are commonly used as rectifiers to turn ac voltages into dc. [A dry cell (mistakenly called a battery, which is a group of cells) will allow electron flow in one direction only, or rather, it will provide current flow in one direction. ]

Actually many rivers run north in North America. Water has no sense of direction. If flows downhill by gravity. Most rivers east of the Rocky Mountains do flow in a southerly direction because the elevation is lower to the south and they are flowing toward the Gulf of Mexico. Source: Riverlorian.com

NO
Blood flow doesn't change direction. They always head for the same direction.
yes :)
the valves
Valves
Various valves keep the blood flowing in one direction.
Valves control the flow of blood. Without them blood could flow backwards.--------------------------Yes, true. Valve would maintain one way traffic for blood right from the heart and to outside parts of the body and form outside to the heart.
The heart is the organ that keeps the blood flowing. Valves in the heart ensure the flow is only in one direction.
It is important for blood to flow in one direction in the heart because blood can't flow backwards because it has oxygen rich blood and poor oxygen rich blood and these to types of blood cannot mix :)
