     • The respiratory system transports oxygen from the air we breathe, through a system of tubes, into our lungs and then diffuses it into the bloodstream, whilst carbon dioxide makes the opposite journey. Air enters the body and is warmed as it travels through the mouth and nose. It then enters the trachea. The trachea divides into two bronchi.

   How does air travel through the body?

   • First, air enters your body either through your nose or your mouth, where it is then held in your nasal cavity/oral cavity. Once inside the nasal cavity, the air passes through the nasal conchae. As it travels, the air makes rapid swirls of movement in order to cause small particles in the air to stick to mucus.

   How does air travel through the bronchioles?

   • One bronchus enters each lung. Each bronchus branches out into smaller tubes called bronchioles. Air travels through these bronchioles. At the end of the bronchioles, the air enters one of the many millions of alveoli where gaseous exchange takes place. Breathing is the term given to the process of taking air into and out of the lungs.

   Air travels from the external environment all the way through to your alveoli, where blood meets up with it through the capillaries. Blood exchange occurs here. The process of which a person takes one breath is called the respiratory cycle.

    Dec 28, 2021 · Air in the lung is humidified; therefore, water vapor pressure alters the pressure. Carbon dioxide mixes with oxygen. Oxygen is moved into the blood and is headed to the tissues. Lungs exert a pressure on the air to reduce the oxygen pressure. It would prevent contraction of the intercostal muscles.
