What else can I help you with?
True or False Arteries have valves to allow blood to flow away from the heart?
true. Arteries have halves that allow for blood flow away form the heard but not toward the heart.
What do arteries contain that prevent the back flow of blood?
Nothing, it is only pressure that keeps blood moving in the right direction in arteries. Veins have valves that prevent backflow of blood, but arteries do not.
What is the function of the valves?
Valves prevent blood from going backward.Valves in general open to allow or close to prevent liquid flow. Heart valves opens to let blood into the heart then close to keep it there so that when the heart muscle contracts and squeezes the blood it is then forced out into the arteries of the body.
Does blood ever flow backwards in the heart?
Arteries have no valves to prevent the blood from flowing backwards, but it is unnecessary when the heart keeps pumping. The blood pressure is highest when the blood is leaving the heart chamber into arteries -- the heart pumping keeps blood going one-way in the arteries.
How do the vavles affect the efficiency of the heart?
The valves of the heart prevent backflow into the arteries. As a result, the heart can efficiently pump the correct amount of blood to the tissues of the body efficiently and rhythmically. -Cheers The valves of the heart prevent backflow into the arteries.

true. Arteries have halves that allow for blood flow away form the heard but not toward the heart.
What do the valves in arteries do?
Valves function to help keep blood flowing toward the heart. Arteries function to carry blood away from the heart.
What part of the heart opens when blood is flowing through?
The valves of the heart open when blood is flowing through, allowing it to move from one chamber to another. The atrioventricular valves open to allow blood to flow from the atria to the ventricles, and the semilunar valves open to allow blood to flow out of the heart into the arteries.

What are the 2 main differences between Arteries and Veins?
Viens carry blood away from the heart while veins carry blood towardj the heart. Arteries are generally thicker than veins because arteries must withstand the pressure of the blood coming away from the heart.
What is the major difference between arteries and veins?
Arteries carry blood away from the heart. Veins return blood to the heart.
Why are valves not present in arteries?
valves are not present in arteries because in arteries there is high blood pressure
What is the function of the valves?

Does blood capallaries have valves?
peripheral veins have valves to help get the blood back up to the heart but arteries do not because they have enough pressure from the pumping of the heart to get the blood out to the body.
What statement is true of arteries?
Arteries carry blood with oxygen to the heart. Veins carry blood full of carbon dioxide to the lungs. Arteries have a thick wall. Veins have a thin wall. Arteries have no valves. Veins have valves.
Does blood ever flow backwards in the heart?
Arteries have no valves to prevent the blood from flowing backwards, but it is unnecessary when the heart keeps pumping. The blood pressure is highest when the blood is leaving the heart chamber into arteries -- the heart pumping keeps blood going one-way in the arteries.
