The Nitrogen we breathe IS absorbed by the blood vessels (and all the body tissues). While the Nitrogen gas from the air is inert and does not play any part in body processes, Henry's gas laws require that some of the Nitrogen will be absorbed/dissolve in the blood (and body tissues). This becomes an issue for sub aqua divers where the presence of this dissolved nitrogen causes the "bends".
maybe marijuana? you smoke it and you inhale the smoke with your lungs..
Oxygen is absorbed into the blood primarily in the lungs. In the alveoli, oxygen diffuses from inhaled air into the surrounding blood vessels in exchange for carbon dioxide, which is then exhaled. This process is facilitated by the respiratory system during breathing.
