What is Malpighian tubule?
Malpighian tubul is an anatomical structure found in the digestive system of insects that live on Earth. Usually, these tubes exclude solid waste products and create an effective way to exclude insects and products remaining insect food. Sometimes Malpighian tubule is used for functions that are specific to a certain type of insects. For example, the larvae of certain types of beetles use the Malpighian tubules to produce silk. Malpighi was one of the first scientists to use a microscope in their studies. He made important discoveries using his lenses. Malpighi was the first to see the capillaries, and saw the first Malpighian Tubule. He is usually considered a father of comparative anatomy and microscopy. Empty tubules to the rectum where the waste is deposited for excretion. The number of tubes varies according to the species. Some have only a few, while others may have hundreds of tubules. The length of the tubules varies depending on how many of them are: insects with several tubules have long, twisted, while insects with many tubules have short structures.
tubules absorb uric acid, which is a by -product of the digestive process of insects, from Midgut. Tubul cells convert acid that is in solution, into crystals of uric acid. This creates a fixed waste product that is similar to birds.
Some species have other Malpighian tubules that have special functions. In the larval stage, there are many larvae and caterpillars tubules that secrete silk. They use material to create a cocoon in which they transform from one phase to the next, and insects lose the ability to create a silk when they ripen into an adult phase. Beetles of the leaves, however, maintains a specialized set of Malpighian tubules into adulthood. They create a sticky material with which the beetle covers eggs.
Malpighian tubule is advantageous for insects because insects make it possible to create solid waste as an alternative to liquid waste produced by mammals, fish and insects of water. Firm productionThe waste saves water, allowing insects to drink longer if access to the water is cut off. It also allows lighter insects because uric acid crystals are lighter than acid in solution.
