Because it is oxygenated blood
When the blood is oxygenated it means that the iron atom (hemoglobin) of erythrocytes has carried the oxygen. The hemoglobin combined with oxygen gives red color to the blood.
Some animals has another atom in blood which is able to bind to oxygen for example octopus blood contains copper which binds to oxygen and it gives the blood a blue color.

Oxygenated blood is bright red, and would only come out of an artery. It will look strikingly different from venous blood which is darker, and what you would generally see if you had a superficial cut.
When blood that is rich in oxygen re enters the heart, the blood enters through the pulmonary valve. The pulmonary valve brings the oxygen rich blood to the pulmonary trunk of the pulmonary artery.
Blood containing red blood cells filled with oxyhemoglobin appears bright red.
Blood enters the nephron first. It enters through the afferent arteriole into the glomerulus, where filtration takes place to form the initial filtrate.
Capillaries. The diffusion of nutrients, oxygen, carbon dioxide and wastes take place in the capillaries. If you want to be more specific, it would be the venous ends of the capillaries where carbon dioxide enters the blood.
