Concept:Arteries carry blood away from the heart. However, not all arteries carry oxygen-rich blood. The pulmonary artery is a key exception.
Explanation:Most arteries carry oxygenated blood from the heart to the body.
But the pulmonary artery is different. It carries deoxygenated blood from the right ventricle to the lungs.
Arteries have thick and elastic walls to withstand high pressure.
The aorta is the largest artery and it carries oxygen-rich blood to the body.
Coronary arteries supply oxygen-rich blood to the heart muscle itself.
The pulmonary vein carries oxygenated blood from lungs to heart, showing veins can also carry oxygen-rich blood.
Option A states "All arteries carry oxygen rich blood." This is false because of the pulmonary artery.
Options B, C and D are true statements about arteries.
Answer:Option A is NOT true.
