Description
Insects possess a unique respiratory system known as tracheal system. This system consists of a network of tiny tubes called tracheae that extend throughout their body. The tracheae deliver oxygen directly to the cells, allowing insects to bypass the need for lungs or respiratory organs. The openings of these tracheal tubes, called spiracles, are typically located on the sides of the insect's body and can be opened or closed to regulate gas exchange.
