As we learnt in
Excretory Structures among Various Groups of Animals -
Insects like cockroaches
- wherein
Malpighian tubules are the excretory structures of most of the insects including cockroaches. Malpighian tubules help in the removal of nitrogenous wastes and osmoregulation.
Ultrafiltration refers to filtration of very fine particles having molecular weight less than 68,000 daltons through malpighian corpuscle. Concentration of urine refers to water absorption from glomerular filtrate as a result of hyperosmolarity in the medulla created by counter-current mechanism in Henle's loop. Urine is carried from kidney to bladder hrough ureter.
Urinary bladder is concerned with storage of urine.
