More recently, however, large variation in insect ventilatory patterns have been documented and insect respiration appears to be highly variable.

With the nostrils and mouth closed, the floor of the oral cavity is then pushed up, which forces air down the trachea into the lungs.

This means that the alveoli have a greater tendency to collapse i. The earlier generations approximately generations 0—16consisting of the trachea and the bronchi, as well as the sysetm bronchioles which simply act as air conduitsbringing air to the respiratory bronchioles, alveolar ducts and alveoli approximately generations 17—23where gas exchange takes place.

It is only in middle of the lungs that the blood and air flow to the alveoli are ideally matched. Cardiovascular system peripheral Artery Vein Lymphatic vessel Heart.
