Webb2 juli 2024 · The inhaled air travels down each primary bronchus and then divides: some air enters the lungs where gas exchange occurs, while the remaining air fills the posterior (rear) air sacs. Then, during the first exhalation, the fresh air in the posterior sacs enters the lungs and undergoes gas exchange. WebbThese air sacs are involved in the exchange of gases. In animals, there are three types of respiratory organs—tracheae, gills and lungs. Insects have a fine system of air tubes reaching all parts of the body. Such a tube is called trachea. Oxygen reaches the tissues through the tracheae.

During active expansion, muscles attached to tall spurs within the abdomen (the apodemes) can lift upward on the tergum (roof of the abdomen), expanding abdominal volume ( 28 ).
