Answer:
Air enters the body through nose and mouth. The air then warmed in the mucous secretions and hair in the nose. It then passes through Pharynx and larynx also called voice box. Then it continues into tube made of cartilage rings called Trachea. Next into two branches of tubes called Bronchi going to similar passageways called Bronchioles/Bronchus. Then the air inhaled is trapped in the air sac called Alveoli . It is where the exchange of gasses takes place in which Oxygen are taken in and the Carbon Dioxide are taken out of the bloodstream then exhaled out of the body. Alveoli are found in a pair of spongy organs called Lungs. The Medulla Oblongata is the one responsible of controlling the breathing by contraction and relaxation.
I'm not smart but I hope it's correct :)
