Detailed explanation-1: -The process of taking air into the lungs is known as inspiration or inhalation, and the process of breathing it out is expiration or exhalation. Air is inhaled through the mouth or the nose. The sequence of air passage during inhalation is as follows: Nostrils→pharynx→larynx→trachea→alveoli.
Detailed explanation-2: -Blood rich in carbon dioxide travels to the heart, which pumps it to the lungs. Carbon dioxide goes from the capillaries around the alveoli into the alveoli. Then carbon dioxide goes up the bronchioles to the bronchi, and then to the trachea to be exhaled.
Detailed explanation-3: -The air enters the body through the nostrils and passes through the windpipe, bronchioles and enters the alveoli. The oxygen from alveoli diffuses into the capillary. Now the oxygen in the lungs will be transported to all parts of the body.
