Answer 1

This type of canal system is formed from the rhagon type by the outfolding of the choanocyte layer.  In this type, oval or rounded chambers lined by flagellated cells are formed by evagination of the radial canals. The surface is perforated by dermal pores These pores lead into incurrent canals, which are found in mesenchyme. These canals are usually branched. In many cases, dermal pores open into subdermal spaces, which are large and provided with spicules. Incurrent canals open into small, rounded chambers provided with flagellated cells. The openings of the incurrent canals into the flagellated chambers are called prosopyles. The flagellated chambers open into the excurrent canals by small apertures, known as apopvles. These excurrent canals are united to form large tubes, which open into spongocoel. This cavity is largely obliterated. Spongocoel opens to the outside by the osculum
