the blood is bright red because of the oxygen from the air
No. Absolutely not! You have varying shades of red only. This is a common misconception because the pigments in our skin and the linings of our veins make it look as if we have blood in our veins. We have deep dark maroon colored blood when there is little oxygen in it, and we have bright scarlet red blood when it has its full capacity of oxygen. Then all the shades in between depend on how much oxygen and/or carbon dioxide is in the blood at the time.

Arterial Bleeding
Because arteries are blood vessels that carry blood away from the heart. There are many arteries that carry blood to all parts of the body. And how dangerous a severed artery is depends on how deep the cut is and what artery is cut.
It Is, That Is Where The Jugular Vein Is. The Jugular Vein Is The Biggest Most Important Vein In The Body And Runs Down Thw Side Of The Neck, If Opened There Is No Way To Close It And It Is Pressurized So It Spurts. All Your Blood Will Be Out Of Your Body Within 4 Minutes.
There is no simple method of observation for vein or atery bleeding. A safe assuming however, is if there is profuse amount at an excessive rate of blood leaving the victim's body they have a severed artery. If this is the case, they will likely die before an ambulance arrives. In either situation, pressure should be applied between the heart and the wound to slow the rate of blood loss.
As it gives out oxegen it looses the bright red
Fresh blood is brilliant red, but as it clots it will turn brown.
Arteries are buried much deeper than veins. Near the heart you can see them throb with the pulse. If you pierce one, the blood spurts out, sometimes in rhythym with the heartbeat. The blood is bright red. Veins are darker in color, don't show a pulse, and don't spurt, but rather drain more slowly. The blood is a darker color from dark red to purple or maroon. In a first aid context, look for the bright red color and stop the arterial bleeding first, best with direct pressure.
