Seastar or starfish belongs to the phylum Echinodermata. Echinoderms have bilateral symmetry, organ system level of organization, show complete metamerism, and are coelomates. They have an endoskeleton of calcareous ossicles, have a complete digestive system , and a water vascular system that serves as respiratory system, circulatory system, excretory system and helps in locomotion, capture, and transport of food. They have tube feet as a part of the water vascular system which are small active tubular projections present on the oral face of the starfish.

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.
