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.
The Respiratory System gets oxygen through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters through the nose and mouth and travels through the larynx and the trachea. The inhaled oxygen then follows a path through your body. At the same time, the blood in the veins releases carbon to alveoli.
