The adaptive variation in the shape of the tooth of vertebrates. Introduction: The digestive system functions to digest the food and absorb the nutrients from them. Vertebrates have specialized organs for digesting the food. Specialization of the digestive system occurs with the presence of mouth and anus, separate organs for the intake of food and elimination of waste products 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.

Nutrition and Digestion Identify the different modes of feeding mechanisms found in the Animal Kingdom, describe each and give 2 example animals for each mode. Why do Cnidarians, Flatworms and Protists have simple or no extensively developed digestive system? (clue: mention their digestive structure and their mode of feeding) What are the structural adaptations of snakes that allowed them to eat and digest a whole prey? Why do insects of one species have a changing diet requirement during their life history? Different birds have varying food habits, discuss the structural and physiological adaptations that allow them to process these foods. What are the four stages of the digestive process, describe each stage/step and indicate what are the products/substances produced and their fate? Discuss the role of the endocrine system in controlling digestion. (no plagiarism pls, thank u!)
