As we know that human system is a very complex system, so its very hard to understand this easily.
After the years and years of research work doctors and researchers understand this phenomena..
Today i am going to discuss about respiratory system.....
Respiratory system involved in the exchange of gases between the organism and environment .
the process of respiration is also present in plants ,animals, and others species likes birds etc .
as we know human respire through taking oxygen into the their cells and giving out carbon dioxide water and energy into the environment . Human being respire through lungs .
As compared to man plants survive by taking carbon dioxide into their cells and and giving out oxygen into the environment .During respiration, diffusion of oxygen from the air into the plant take place through the leaf stomata.
