Sponges do have several distinct types of cells, each with different functions. (See FIG.) The body wall of a sponge is perforated by numerous pores or ostia through which water is drawn into a central cavity called the spongocoel or central cavity. The osculum is a large opening at one end of the sponge through which all the resulting excurrent is evacuated.
The main function of red blood cells is the transport of oxygen from the lungs to the body's cells. Red blood cells contain a protein called hemoglobin that actually carries that oxygen. In capillaries, oxygen is released to be used by the body's cells. Ninety-seven percent of the oxygen carried by the blood from the lungs is carried through hemoglobin. The other 3 percent is dissolved in the plasma.
