Spiracles are small openings found on the bodies of certain animals, particularly invertebrates like insects and arthropods. These openings serve as entry points for air, allowing the organism to breathe. Spiracles are typically located on the sides of the body and can open and close to regulate airflow and minimize water loss. In insects, spiracles connect to a network of tubes called tracheae, which transport oxygen directly to tissues. This system is efficient for their small size, enabling them to thrive in various environments. Spiracles play a crucial role in the respiratory system of these creatures, ensuring they receive the oxygen needed for survival.
