Do arteries reproduce or does the human body make new arteries?
Arteries do neither
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.
What carries oxygen from the lungs to the heart?
The pulmonary veins. The word vein is deceiving, because the pulmonary veins are the only veins in the body that carry oxygenated blood. They carry oxygenated blood from the lungs to the left atrium, and from there it goes to the left ventricle, to the aorta, and then to the rest of the body.
How blood is prevented from flowing from the ventricles back into the atria?
There are two factors that prevent flow of blood fronm arteries to ventricles 1. presence of semi-lunar valve at the base of pulmonary arch and systemic arch 2. The pressure difference b/w ventricles and artries. The pressure in ventricles is lower than that of arteries and according to Equation of contunity fluid never flows from higher pressure to lower pressure

What vessel carries oxygen-rich blood to the lungs?
the right ventricle, ( just to make sure you know, the rights and lefts of the heart are opposites) pumps blood through a valve, and up to the pulmonary vein where it travels to the lungs to be oxygenated by the alveoli, and brought back through the pulmonary artery to were the left atrium and ventricle pump the blood to the aorta, where then is distributed to the brain muscles and body
Do arteries reproduce or does the human body make new arteries?
Arteries do neither
Why does the blood go to the lungs via the pulmonary arteries?
The pulmonary arteries function to deliver blood to the lungs to acquire oxygen. In the process of respiration, oxygen diffuses across capillary vessels in lung alveoli and attaches to red blood cells in the blood. The now oxygen-rich blood travels through lung capillaries to pulmonary veins.
Does the pulmonary vein contain oxygen poor blood?
Yes. After the right ventricle pumps the oxygen-poor blood to the lungs (through the pulmonary arteries), the pulmonary veins carry the oxygenated blood back to the left atrium of the heart.Because blood vessels are classified by whether they lead into or away from the heart, the pulmonary veins are carrying oxygenated blood, whereas the pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs.
What are some unique baby names for boys?

What Do Arteries Do In The Body?
arteries as a rule carry pure/oxygenated blood from left ventricle to different parts of body except pulmonary artery which carries impure , deoxygenated blood. Thus every role which is attributable to some extent to arteries. one of the important function of blood can be understood by role of hot water pipes used as a heating system, in the same way arteries distribute heat to whole of the body by distributing blood. arteries supply nutrients to all the body cells except few(e.g. retina) and hence make their survival possible.
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.
