WebMar 29, 2024 · This video covers the gaseous exchange system in insects, focusing on the structure and the process of gas exchange. There are similarities to the mammalian gaseous exchange system.... 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. Some small insects do demonstrate continuous respiration and may lack muscular control of the spiracles. Others, however, utilize muscular contraction of the abdomen along with coordinated spiracle con… f1hst.com
