The protein hemoglobin, which carries oxygen in the blood and appears brighter red in the vessels that carry oxygen. In the veins, the hemoglobin has already given up most of its oxygen to the body. Therefore the blood turns a darker red.
Dark red blood is oxygen-poor. Bright red blood is oxygen-rich.
Oxygen-poor blood is dark red; oxygen-rich blood is bright red.
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.
Yes, oxygenated blood is bright red
They are transported to an oxygen rich environment, the lungs. It is there that they pick up their oxygen.
Veins are blue because the blood is poor in oxygen, arteries are red because the blood is rich in oxygen.
When blood cells have oxygen they are red, when they have no oxygen they are a darker shade of red. The more haemoglobin the blood contains the more oxygen is going to attach to the iron which is the most important element of the haemo-globin.
Oxygen rich blood is physically transported by arteries; which lead away from the heart. Oxygen depleted blood is transported back to the heart by veins. Arteries are bigger than veins and are set deeper within the body. Within the veins and arteries are red blood cells that technically "carry" the oxygen. Red blood cells are composed of the protein haemoglobin which is rich in iron. It is the iron that enables the red blood cells to "carry" the oxygen by forming a chemical bond with the oxygen atom.

it is red as it is rich with oxygen
Sharks have two types of muscles, red and white. The red muscle is slow contracting and needs oxygen-rich operating environment. The white muscle is quicker at contracting, but does not need the oxygen-rich operating environment.
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.
