when we breathe in air it goes to the lungs into the alveoli and oxygen diffuses into blood capillaries
after that when we eat the food is "burnt" with oxygen that helps nutrients diffuse into capillaries in villi

In living organisms,respiration occurs at two levels; at the body level and at the cellular level.In case of the respiration occuring at the body level , oxygen and carbon dioxide are exchanged between the body and the surrounding . Cellular respiration occurs by two methods , namely aerobic respiration ( oxygen is involved ) and anaerobic ( oxygen is not involved ) . In anaerobic respiration,glucose is oxidized in three steps ,that is glycolysis , tricarboxylic acid cycle ,and electron transfer chain reaction . Anaerobic respiration involves only two steps : glycolysis and fermentation.
