How do insects relive themselves?

Insects relieve themselves through a process called excretion, primarily using a structure called the Malpighian tubules. These tubules filter waste products from the hemolymph (insect blood) and transport them to the gut, where water is reabsorbed, and solid waste is formed. The waste is then expelled through the anus. This process efficiently conserves water, which is vital for their survival in various environments.
