Answer:
We breathe to supply our bodies with oxygen and expel carbon dioxide. Oxygen is essential for the process of cellular respiration, where our cells use oxygen to convert nutrients into energy. Breathing allows us to take in oxygen from the air and release carbon dioxide, a waste product generated by our cells' metabolic processes. This exchange of gases occurs in the lungs through the process of inhalation and exhalation, ensuring our bodies receive the oxygen needed to sustain life.
