True.
Selective reabsorption of materials occurs via cells lining the tubules in protonephridia and via capillaries in metanephridia.
Two nephridia kinds that are primarily seen in invertebrates are protonephridia and metanephridia. They are in charge of eliminating metabolic waste from the body and are generally functionally similar to the vertebrate kidney.
Protonephridia and metanephridia are two types of excretory glands, however, metanephridia are an excretory gland type with a ciliated funnel opening into the body cavity. Protonephridia are a network of dead-end tubules without internal openings. The fact that protonephridia are closed by a flame cell while metanephridia have an opening to the body cavity and are not closed by flame cells is another significant distinction between the two.
