The carbon dioxide is exchanged for new oxygen in the alveoli of your lungs.

In the blood, most of the carbon dioxide is carried in the blood plasma. Only little carbon dioxide is carried in the haemoglobin of the red blood cell in the form of carboxy-haemoglobin.
The carbon dioxide is carried in the veins to the right atrium of the heart and then it enters the right ventricle of the heart to be pumped to the lungs. Then carbon dioxide diffuses across the one cell thick blood capillaries near the alveoli of the lungs and then it is excreted from the lungs.

The red blood cells carry the carbon dioxide back to the lungs where tiny sacs called aveoli exchange the oxygen we breath in with the carbon dioxide we breath out.

It takes it back into the lungs.
You then breathe out, and the CO2 is ejected from your body as waste products to be photosynthesized by plants.

back to the lungs so it can be released to the air through the nose
