Lungs:

Lungs are the largest part involved in respiration. It takes in clean air from outside (containing oxygen) and expels out dirty air (containing carbon dioxide). Oxygen in lungs is taken in by blood and transported to cells of the body. There's hemoglobin cells in blood which do this job of taking that oxygen in. The cells use oxygen to burn carbs, generate energy but generate Carbon dioxide as a by product. This Carbon dioxide is transferred back to blood which is carried to lungs. It's here that lungs take that CO2 and expel it out.
