WebThe gas exchange system of an insect is always at a risk of drying out due to them living on land. This is why the gas exchange system of an insect is internal, so as much moisture as possible is held in due to the humidity inside the insect’s body. Insects get oxygen from the air which has a high concentration of oxygen compared to in water ... WebGases diffuse faster in air than through water. The surface area of the tracheoles exposed to air increases. Large insects contract muscles associated with the abdomen to force air in and out of the spiracles. This is known as 'abdominal pumping'.

Tracheal System and Respiratory Gas Exchange SpringerLink

WebIn most insects that demonstrate discontinuous gas exchange, spiracle movements and active ventilation are closely coordinated by the nervous system to generate unidirectional air flow within the tracheal system. [2] This coordination leads to the highly regulated bursting pattern of CO 2 release. WebA large number of tracheoles run between cells and into the muscle fibres - the site of gas exchange; For smaller insects, this system provides sufficient oxygen via diffusion; Image showing the structure of the tracheal system of an insect.

"WebIn insects, gaseous exchange occurs through a network of tubes collectively known as the tracheal system. The small openings on the sides of an insect’s body are known as spiracles. Oxygen-rich air enters through the spiracles. The spiracles are connected to the network of tubes. From the spiracles, oxygen enters the tracheae. " - Gaseous exchange in insect

Insects were once believed to exchange gases with the environment continuously by the simple diffusion of gases into the tracheal system. More recently, large variation in insect ventilatory patterns have been documented, suggesting that insect respiration is highly variable.
