The effect of the structure of the digestive tract in different invertebrates on the size of the organism they can eat. Introduction: The invertebrates are those organisms that lack a back bone. Every organism has a different method of digestion depending on the structure of their digestive system . For example, the sponges have a filter feeding mechanism in which they take up water from the surrounding in their siphons and filters it to obtain microbes or nutrient particles and utilize it as a source of food.

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.
