Most arteries are high in oxygen except for the pulmonary arteries.
Most veins carry blood low in O2 The only veins that carry blood high in oxygen are the pulmonary veins.
Do you mean 'When does blood carry the most O2'?
Well during exercise as your breathing rate is increased it would also increase the ammount of o2 in your blood, or when you're out in an open space. But mainly during daytime. *Also your heart beats faster when you do exercise so therefore more blood would be pumped around.

arteries
The blood vessel that carries deoxygenated (low oxygen) blood away from the heart is called the pulmonary artery. This artery carries blood to the lungs where it picks up oxygen and then travels back to the heart to be pumped out to the cells of the body. The best way to remember this is to remember that pulmonary means lungs and artery means a blood vessel that carries blood away from the heart. Most arteries carry blood that is rich in oxygen. The pulmonary artery is an exception.
haemoglobin carries oxygen in the blood

In the umbilical cord you have one vein and two arteries. This vein goes to the liver of foetus. This blood vessel contains most oxygen and food in case of foetus. After birth this vessel gets obliterated to form the falciform ligament.
The Erythrocytes, more commonly known as red blood cells carry oxygen to the body.
The Aorta would have the most because it leads from the heart to the rest of the body. The Aorta is the body's largest artery. It is the main blood vessel carrying oxygenated blood from the heart.
A red blood cell carries Oxygen and Carbon DIoxide
blood mainly carries oxygen and nutients (end products of digestion) to the body cells. the waste gas that blood carries away from the cell is called Carbon dioxide
Any vein, Artery or cappillary can be classed as a blood vessel as they all carry blood around the body. To be considered an artery the blood vessel must carry blood away from the heart. To be considered a Vein the blood vessel must carry blood towards the heart. A cappillery is an incredibly small blood vessel, it has walls thin enough to allow gasses to pass through, from the blood, to the body and vice versa. NB:- Most veins carry de-oxygenated and most arteries carry oxygenated blood. However, this is not allways the case. For example, the pulmonary vein carries oxygenated blood from the lungs to the Heart. Also, the Pulmonary artery carries de-oxygenated blood from the heart to the lungs. hope this helps
The Pulmonary Vein carries oxygenated blood from the lungs to the left atrium of the heart.
