Blood is bright red due to the high concentrations of oxygen in it. This blood is known as oxygenated blood. Blood that appears dark in color or "blue" is blood that has been used by the body and has a higher concentration of carbon dioxide in it. This blood in known as deoxygenated blood!
The vessel that brings blood back to the right atrium is the superior vena cava and the inferior vena cava.
Oxygen enters your blood stream in your lungs. Inside your lungs the air pipe branches into smaller pipes which branch a number of times eventually forming 'alveoli'. The great amount of braching increases the surface area so there is more area for oxygen excahnge to occur, making the process more efficient. In the alveoli the capillaries are very close to the surface, so close that the oxygen gas can move across the thin wall into the blood stream. This is facilitated by haemoglobin which attracts and bonds with oxygen molecules.

When two incompatible blood cells mix and come into contact with each other, a reaction called agglutination occurs. This can lead to clumping of the blood cells, which can block blood vessels and cause serious health complications.
brings more air into contact with the receptors..
Blood in the capillaries are never in direct contact with air. Blood in contact with air is called bleeding. Oxygen, carbon dioxide (and other gases) diffuse across the alveolar and capillary walls to enter the blood stream (and leave).
The respiratory system removes carbon dioxide from the blood and brings oxygen into the blood. This process occurs through the lungs, where oxygen from the air is exchanged for carbon dioxide in the blood.

? Are you asking what color does blue blood turn after it comes in contact with air? Red!
The inferior vena cava brings blood from the lower parts of the body to the heart. The blood is deoxygenated.
Vein
There are two, the Superior Vena Cava that brings blood from the head, and the Inferior Vena Cava that brings blood from the lower body.
! im pretty sure your mouth also brings air into the body
Blood clotting does occur for blood in uninjured blood vessels due to its insulation from air. Our bodies produce what is called heparin that prevents clotting of blood in vessels. Heparin allows our lungs to transfer oxygen to our blood. When blood is exposed to air it clots so heparin allows the blood to come in direct contact with the air we breath without clotting.
