In Arteries, blood has already obtained the oxygen, which gives blood it's red color.
In veins, blood is returning back to the heart and lungs for oxygen. Oxygen-deprived blood is a bluish/purple.
your arteries contain white blood cells and red blood cells.
The blood in arteries is typically bright red because it is oxygenated and rich in hemoglobin.

The blood in ARTERIES is BRIGHT RED beacuse it is rich in oxygen. :)) -Zuri
Arteries carry oxygenated blood from the heart.
red blood cells
Systemic Arteries are represented as red in diagrams because they have oxygen in the blood, whereas Pulmonary Arteries are represented as blue because they carry deoxygenated blood.
It is red, because in it, there is red blood cells, which is the color red.
Arteries
oxygen rich blood is red, while oxygen poor blood is blue. this is the reason that blood in your arteries are always red, and blood in your veins are always blue.
The pulmonary arteries are the only ones not carrying oxygenated blood. Arteries transport blood away from the heart and veins are to carry blood back to the heart. When you think this way, you may be able to visualize which vessels has oxygenated blood.
oxygenated blood is a bright red (in arteries), deoxygenated blood is a dull brick red (in veins).
