Even thought its not part of the digestive system teeth are very resourceful for aiding digestion‚ in all Herbivores they have a Horny pad which helps initially crush the food and a meeseter that is larger than that of a carnivore so it can chew for longer‚ they have cainines at the front and molars and pre molars that grind at the back‚ so that the foodis crushed and soft making the break down and digestion of food easier. Example: Cow chews its food for a long time to crush it andmake it easier

salivary glands‚ liver and pancreas are considered to be accessory digestive organs. These organs produce saliva (salivary glands)‚ bile (gallbladder and liver) and digestive enzymes which contribute to the breakdown process of food. Mechanical digestion begins with the process of taking food into the mouth or ingestion and chewing it until it can be moved through the alimentary canal during the propulsion process. This process includes swallowing and in a series of muscle contractions and relaxation

functionally a digestive organ. . Mouth The process of digestion begins in the mouth where food is chewed until it reaches a consistency whereby it can be swallowed. The following accessory structures aid this early stage of digestion: Tongue — a muscle that is covered by taste buds. It assists the process of chewing and man oeuvres food to a position where it can be swallowed easily. Salivary glands — begin the process of chemical digestion through the secretion of the enzyme‚ salivary amylase

providing energy and nutrients to the body‚ six major functions take place in the digestive system; Ingestion‚ secretion‚ mixing and movement‚ digestion‚ absorption‚ and excretion. The mouth is where food begins its journey through the digestive system in the mouth‚ also known as the oral cavity. Inside the mouth are many accessory organs that aid in the digestion of food‚ the tongue‚ teeth‚ and salivary glands. Teeth chop food into small pieces‚ which are moistened by saliva before the tongue and other

acid (HCL)‚ it is a term that covers all digestive enzymes. The process of digestion‚ absorption and assimilation begins with the enzymes present in the saliva that soften what we eat so it continues into the gullet as a paste. Penetrating the diaphragm‚ this gullet ends in a strong‚ muscular bag we know as the stomach. Having taken about 3 seconds to reach here‚ this foodstuff is turned acidic by the HCL for further digestion by peptin and gastrin before it enters the small intestines where this acid
