lungs
Block your nostrils/nares and mouth, or obstruct the trachea/windpipe. The nostrils/mouth are only ways in which your body takes in air and the trachea is the only passage that delivers air to the lungs. Therefore, blocking them would effectively cut off your air supply.
The Trachea
People breathe through their nostrils, and can also breathe through their mouth. If you block those, no air will get in. Of course, this results in death, so I would not normally recommend it.
