Why is the direction of the wave of contraction so important in the heart?
The direction of the wave of contraction in the heart is important because it decides where the blood reflux will take place. The blood reflux could take place in the atria, or the blood from the heart could be ejected into the pulmonary artery or aorta.
How part of the theory of circulation was changed?
People used to think that blood could flow in any direction in the veins. William Harvey came up with evidence used to show that blood moved only in one direction through veins. He discovered that the valves in the veins permit blood to flow in one direction only. He said that blood circulates in only one direction through the body and returns to the heart.
What blood vessel delivers blood to the muscles of the heart?
The coronary arteries deliver blood to the muscles of the heart.
What carries blood from your body back to the heart?
The veins carries the blood back to the heart using the circulatory system. It then stores the blood in the arteries and the heart pumps it back around the body.
What happens when your blood pressure rises?
High blood pressure can harden your arteries, which decreases the flow of blood and oxygen to your heart and lead to heart disease.
Why does blood flow in the direction it does?
the blood does not flow in the wrong direction because it flows in veins.
How do valves prevent blood from flowing in the wrong direction?
valves help prevent blood from flowing in the wrong direction by opening and closing at the right time to let the heart pump blood effectively.
How does the blood to a heart and lung keep flowing in the same direction?
There are two ways that blood is kept flowing in the same direction. The heart is pumping it in that direction, and blood vessels contain valves which prevent blood from flowing in the wrong direction.
What prevent the blood from flowing in the wrong direction through the heart?
Valves.
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.
What are the flaps that make blood go in one direction?
In veins, there are valves that prevent back flow. <><><><><> There are also valves in the heart to force the blood to go in one direction only when the heart contracts.
What structures of the heart keep blood flowing in one direction.?
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.
Why does the heart has valves?
Valves are the "doors" which allow the proper amount of blood into each ventricle of the heart so it does not "explode" or push too much into the body. When high blood pressure occurs the culprit can be a defective valve that is leaking or failing to open and close properly. Not many people have that type of high blood pressure. There are many types of high blood pressure which doctors can determine by listening to the valves in the heart or elsewhere.
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.

Why are valves needed in the main arteries leaving the heart?
stop the blood going in wrong direction.
Keep a one way flow through the heart?
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 :)
