1 (The nose and mouth make up the first part where air enters your body. 2  The trachea, or windpipe, is the second part and it delivers air to the lungs. 3  Your lungs are the third part where oxygen is absorbed by the blood, which brings it to the rest of the body. 4  Finally, the diaphragm is the fourth part.
Oxygen is transported throughout the body via hemoglobin in the red blood cells. Oxygen transport and exchange provide the necessary oxygen to the body. This process is called respiration. Air is breathed in through the mouth and nose and after various processes it enters the blood through diffusion. The oxygen enters the red blood cells and in exchange carbon dioxide is taken out.
