Why is it in correct to say that all arteries carry oxygenated blood and all veins carry dioxygenated blood?
That's mostly always true. The actual definition of an artery is that it carries blood away from the heart. A vein is blood vessel that carries blood towards the heart. In general, when blood is traveling away from the heart it is oxygenated because it's supplying the rest of the body with blood. And vice versa is true, blood coming towards the heart is usually deoxygenated because the body has already taken the essential substances out.
This rule is not true in the heart. The inferior vena cava (veins) brings blood to the right atrium of the heart and then the right ventricle. At this point the blood is not oxygenated. The ventricle pumps the blood through the pulmonary artery (still deoxygenated, but its going away from the heart) into the pulmonary circulation (the lungs). It picks up the oxygen there and now the blood leaving the lungs is oxygenated. The pulmonary vein brings oxygenated blood FROM the lungs TO the heart (toward the heart). Pulmonary vein empties into the left atrium and then into the left ventricle which then pumps the blood into the aorta (an artery) away from the heart and into the systemic circulation.
What else can I help you with?
What is the correct sequence of the veins and arteries?
the arteries carry oxygen rich blood to all parts of the body. the veins return the blood to the heart to get oxygenated
Is the blood in arteries oxyenated or deoxygenated?
The blood in arteries is usually oxygenated because arteries carry blood away from the heart.
What make the pulmonary arteries unique among arteries?
they are the only arteries that carry de-oxygenated blood.
What makes the pulmonary artery different from all the other arteries?
The pulmonary artery runs from the heart to the lungs. It is the only artery that doesn't carry oxygenated blood. That makes it a darker red than the blood in other arteries, so it looks blue under your skin.
Which vessels carry blood away from the heart- vain or arteries?
Pulmonary arteries carry oxygenated blood away from the heart. Veins carry blood to the heart.
What is oxegenated?
Oxygenated means something has oxygen in it. For example, the heart pumps oxygenated and dioxygenated blood around the body.
What type of blood are the arteries responsible transporting?
Oxygenated blood is carried by all arteries but one which is the pulmonary artery
Which veins carry oxygenated blood?
They don't, arteries carry oxygenated blood
The bloodin arteries is?
The blood in the arteries is oxygenated.
What is the correct sequence of the veins and arteries?

Do arteries carry oxygen?
oxygenated blood the arteries have
What do arteries deliver?
oxygenated blood
Oxygenated blood is found in all arteries of the body. Is this true or false?
False. Oxygenated blood is found in the systemic arteries, which carry blood away from the heart to the body, but not in the pulmonary arteries, which carry blood from the heart to the lungs for oxygenation.
Difference of pulmonary arteries to ordinary arteries?
All arteries carry oxygenated blood except pulmonary artery. Pulmonary arteries carry deoxygenated blood to the lungs where it becomes oxygenated.
What carry's oxygenated blood?
Arteries carry oxygenated blood to the rest of the body from the aorta of the heart.
What arteries carry?
Arteries Carry oxygenated blood away from the heart
