It also has a permeable coat which tends to stick to the mucus‚ hence it will move down the alimentary

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

DIGESTIVE SYSTEM Digestion is a process of breaking down complex food molecules into simple ones‚ suitable for absorption and their subsequent utilization in our body PURPOSE to convert complex food molecules into simpler ones‚ suitable for absorption and utilization production of energy‚ necessary for survival & vital chemical activity growth & development of the body repairing function reproductive function lactation FUNCTION to keep the
Premium Bile acid Digestive system Stomach
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

prevent food from clogging these airways. 16. During digestion‚ enzymes such as amylase break chemical bonds between the sugar monomers in starches. Digestive enzymes also break down foods and make the nutrients available to the body. 17. Mechanical digestion includes the muscles of the stomach contracting to mix stomach fluids and food which produces a mixture known as chyme. Chemical digestion includes the production of acids that aid the digestion and absorption of food. 18. In the stomach‚ hydrochloric
