porocyte
Quick Summary
Porocytes are large, tubular cells found in some sponges that form the walls of incurrent canals. These canals are part of the sponge's water-current system, which is essential for its survival. Sponges, belonging to the phylum Porifera, are primitive aquatic animals that lack definite organs, nervous systems, and musculature. Their water-current system, consisting of pores, canals, and chambers, circulates water to bring food and oxygen, and to remove waste. Porocytes can contract, helping to close the pores during unfavorable environmental conditions.12345
