Why is the following statement false? All arteries carry oxygen-rich blood, while all veins carry oxygen poor-?

Arteries carry blood from the heart, and veins return blood to the heart. Since the blood pumps oxygen poor blood from the heart to the lungs, this artery (pulmonary) has oxygen poor blood. The vein (Pulmonary vein) that returns blood from the lungs to the heart to be pumped to the rest of the body contains oxygen rich blood. So that statement is false.Why is the following statement false? All arteries carry oxygen-rich blood, while all veins carry oxygen poor-?
All arteries carry oxygen-rich blood, while all veins carry oxygen-poor....


This is a false statement because of the word used-'all.'


The pulmonary vein actually carries oxygenated blood.


Actually, the statement should be all arteries carry oxygen-rich blood, while all veins carry carbon-dioxide rich blood.


If you like the answer, please choose it as the best answer. Thanx!Why is the following statement false? All arteries carry oxygen-rich blood, while all veins carry oxygen poor-?
This is the general rule but it doesn't apply to the pulmonary veins or arteries. They are the opposite of this statement. Veins carry blood to the heart, arteries carry blood from the heart. It doesn't matter whether the blood is oxygenated or deoxygenated.
Pulmonary arteries carry deoxygenated blood from the heart to the lungs, pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart. Veins refer generally to blood flow toward the heart, arteries refer to blood flow from the heart
What happens in your lungs where pulmonary arteries carry oxygen-poor blood and the pulmonary vein carries oxygen-rich blood?
