Collar cells have long tails or flagella that line the inner sponge cavity and funnel water. Specialized cells, called collar cells, have flagella that move water through the pores in a sponge. But they do have unique, specialized cells that help them survive. ependymal cell, type of neuronal support cell ( neuroglia) that forms the epithelial lining of the ventricles (cavities) in the brain and the central canal of the spinal cord. then engulfed via endocytosis by the collar cells that line body cavity. True, they don’t have nerves, muscles, or organs. filter feeders -water moves through sponge and microscopic food are. Each time you breathe out, air leaves the alveoli and rushes into the outside atmosphere, carrying waste gases with it. Sponges may seem simple, but there’s more to them than meets the eye. The blood in these capillaries also releases carbon dioxide into the air inside the alveoli. Oxygen in the air inside the alveoli is absorbed by the blood in the mesh-like network of tiny capillaries that surrounds each alveolus. In fact, alveoli in the two lungs provide as much surface area as half a tennis court! Each time you breathe in, the alveoli fill with air, making the lungs expand. The morphology of the simplest sponges takes the shape of an irregular cylinder with a large central cavity, the spongocoel, occupying the inside of the cylinder (Figure 1). trovascular cavity break up the prey, cells lining the cavity. ![]() Only vertebrates possess a true endothelial lining, defined as a layer of epithelial cells. ![]() The two lungs may contain as many as 700 million alveoli, providing a huge total surface area for gas exchange to take place. most sponges feed by sieving food out of the water. Invertebrate vessels are always lined by extracellular matrix. These tiny air sacs are the functional units of the lungs where gas exchange takes place. ![]()
