---------------------------------------------------------------------------------------------------------

respiration is a complex process which starts with inhalation and exhalation.so here are the steps involved in it.,

1. inspiration
2. the air enters into lungs
3. it reaches into bronchi ⇒ bronchioles ⇒ alveoli ⇒alveolus.
4. here the oxygen is absorbed by blood capillaries.i.e., oxygen from alveolus diffuses into blood and carbondioxide from blood to alveoli.
5. then the oxygen enters cell.there occurs cellular respiration by which ATP  bonds are broken and energy releases.
6. and simultaneously., carbondioxide goes out i.e. exhalation.

• don't confuse breathing with respiration.
• breathing is just about inhaling and exhaling
• but respiration inhaling oxygen, mixing of it with blood and releasing energy in the body.
