WebThe cryptonephric Malpighian tubules within the rectal complex are bathed in fluid within a functional compartment, the perinephric space, which is separate from the haemolymph. In this study, the scanning ion-selective electrode technique (SIET) was used to measure transport of Na+ and K+ across the rectal complex and across multiple regions ... WebMay 1, 1993 · It appears that in this complex Mas-DH is acting on a Na + /K + /2Cl − co-transporter, presumably on the basal membrane of the cryptonephric Malpighian tubules, because Mas-DH-stimulated fluid absorption by the cryptonephric complex is inhibited by bumetanide or the removal of Cl -, Na + or K + from the haemolymph side of the tissue.

WebJan 1, 2024 · Malpighian tubules (MTs) and the hindgut together constitute the excretory system of insects.
