NEET BIOLOGY

Detailed explanation-1: -Malpighian tubules are thin, yellow colour filaments. About 100-1050 tubules are present at the junction of the midgut and hindgut. Malpighian tubules help in the removal of the excretory product from the haemolymph.

Detailed explanation-2: -Malpighian tubules line the gut of some species of arthropods, such as bees. They are usually found in pairs in the posterior regions of arthropod alimentary canals; the number of tubules varies with the species of insect.

Detailed explanation-3: -The excretory organ in a cockroach is the malpighian tubule.

Detailed explanation-4: -The Malpighian Tubules (MTs) are the main excretory organs in most insects. They play a key role in the production of primary urine and osmoregulation, selectively reabsorbing water, ions, and solutes.

Detailed explanation-5: -The Malpighian tubules of cockroaches take nitrogenous waste products from the haemolymph and convert them to uric acid, which is excreted.
