The question is a little vague but I think it's referring to the difference in color between blood in the arteries and veins. Blood in the arteries is bright red. It is coming from the heart, by way of the lungs where it picks up oxygen, and then goes out to the tissues of the body to deliver it's oxygen. After the blood has delivered the oxygen it appears darker as it travels in the veins back to the heart. So "dark blood" would be found in the veins.
arteries are red. veins are blue to whoever said the opposite.

No the heart pumps the blood but it does pump the blood through the arteries.
The only arteries in the body that move deoxygenated blood away from the heart are the pulmonary arteries. Arteries are blood vessels.
Arteries carry blood to all parts of the body.
Yes, but this would be seen in arteries and they do not take blood for donations from arteries.
Arteries.

The arteries carrying blood to the lungs contain deoxygenated blood. In contrast, other arteries carry oxygen-rich blood.
the three blood vessels are the Veins capillaries Arteries the arteries.

Arteries ALWAYS bring blood away from the heart. Vein bring it back.
arteries are blood vessels that carry blood away from the heart
No the heart pumps the blood but it does pump the blood through the arteries.
your arteries contain white blood cells and red blood cells.
Away. Arteries carry blood away from the heart. The blood, they carry, is oxygenated, with the exception of the pulmonary arteries. While pulmonary arteries also carry blood away from the heart (to the lungs), the blood is deoxygenated.
