Describe how the water vascular system of an echinoderm functions.
Water enters the tube feet then travels through the radial canals. It is released on the dorsal side of the animal.

Controls water pressure and allows the echinoderm to pump water through its body for respiration and locomotion
Describe how the Amoebocyte functions in the digestive process of a sponge
Food particles are engulfed via phagocytosis and transferred to Amoebocyte. The Amoebocyte transfers nutrients to other cells of the sponge
Describe how choanocytes function in the digestive process of a sponge
The beating of flagella lets Choanocytes create a current that draws water in. Food particles are then engulfed via phagocytosis
