Explanation:
HUMAN respiratory system is one of the most important life processes in living organisms
there are two types of respiration
1]body level respiration
2]cellular level respiration
in body level respiration there is an exchange of oxygen and carbon dioxide between our body and the surrounding
many organs like the diaphagram,alevoli lungs, nose, cells [mitochondria present in it] helps in respiration
