Question

Why is it incorrect to state that arteries carry oxygenated blood and veins carry deoxygenated blood?

Answer 1

Answer: It is incorrect because arteries carry deoxygenated blood and veins carries oxygenated blood.

Step-by-step explanation:

Veins are blood vessels that carries blood to the heart. Most veins carries deoxygenated blood with the exception of pulmonary veins that carries oxygenated blood from lungs to the left atrium of the heart.

Arteries are blood vessels that carries blood away from the heart. Most arteries carries Oxygenated blood with the exception of Pulmonary arteries that are responsible for carrying deoxygenated blood from the right ventricle to the lungs. When the blood passes through the alveoli, it become oxygenated which is a process of respiration.

Answer 2

Since pulmonary artery carries deoxygenated blood while pulmonary vein carries the oxygenated blood.

Step-by-step explanation:

It is incorrect since it is not true for all the arteries and veins present in the body. The arteries such as the pulmonary artery deliver the deoxygenated blood from the right ventricle of the heart to the lungs. On the other hand, the pulmonary vein carries the oxygenated blood from the lungs to the left atrium of the heart. Therefore, arteries carry the blood away from the heart while the veins carry the blood towards the heart.
