Incurrent canals definition
WebIt is estimated that water enters through more than 80,000 incurrent canals at a speed of 6cm per minute. However, because Leuconia has more than 2 million flagellated chambers whose combined diameter is much greater than that of the canals, water flow through chambers slows to 3.6cm per hour. WebThe body walls of the second sponges show two types of the canal system, radial canal system and in current canals. The radial canal is flagellated because of the presence of choanocytes. The water enters into the body through Ostia, which are pumped to incurrent canal followed byprosophyles.
