Detailed explanation-1: -This paper describes the different regions of the Malpighian tubules and the associated structures (ampulla, midgut, ileum) in the cockroach, Periplaneta americana. There are about 150 tubules in each insect.

Detailed explanation-2: -The malpighian tubules are the excretory organ of cockroach which excretes nitrogenous products and other remains of metabolites. It is present at the junction of the midgut and hindgut. These are fine, yellow-coloured and branched threads present in bundles, approximately about 150 in number.

Detailed explanation-3: -This system helps in the absorption of water, solutes, and waste from the surrounding tissue that is the hemolymph. In the form of calcium oxalate and nitrogenous molecules, these wastes are released into the surrounding. Malpighian tubules in humans are absent.

Detailed explanation-4: -Malpighian tubules are excretory organs of insects. These are unbranched tubules lying almost freely in haemocoel and open into alimentary canal. The main function of these tubules is to absorb nitrogenous waste product. Spiracles are the respiratory systems of insects through a series of external openings.

Detailed explanation-5: -The malpighian tubules are the excretory organ of the cockroach that excretes nitrogenous products and other metabolite remnants. It can be found near the intersection of the midgut and the hindgut. These are delicate, yellow-colored, branching threads that come in bundles of roughly 150. More items
