what is respiration in chemistry?
Respiration means breathing. When we inhale we take in oxygen and when we exhale we release carbon di oxide which is one of the waste products of our body. When we take in oxygen, it is directed to our lungs from where it enters blood and goes around our body to every organ- heart liver stomach etc...every part of our body and supplies oxygen to them. Organs and parts of our body need this oxygen to give them energy to function. When blood gives oxygen to the body organs and parts, in turn the organs give bak carbon di oxide to blood and this carbon di oxide then reaches lungs through blood and is exhaled out. So this is a very basic definition about the complex process of respiration.
