The Important Role Of Yoga In Digestive System



The organs comprising this system are: the​ mouth,​ the​ pharynx,​ the​ gullet (foodpipe),​ the​ stomach,​ the​ duodenum,​ and the​ small and large intestines. From the​ viewpoint of​ the​ science of​ diet,​ the​ food we​ consume should enfold five constituents,​ namely,​ carbohydrates,​ proteins,​ fats,​ mineral salts,​ and vitamins. the​ first three constituents in​ this list are supposed to​ yield energy that is​ requisite for the​ life activity of​ an​ individual. One gram of​ carbohydrate or​ protein gives 4.1 calories of​ energy,​ while one gram of​ fat is​ found to​ give 9.2 caloriesof energy. we​ acquire large sum of​ carbohydrates from cereals,​ potatoes,​ sugar,​ etc. the​ proteins,​ in​ accumulation to​ supplying energy,​ perform another important function,​ that of​ building the​ muscles of​ the​ body. They are of​ two types,​ namely,​ plant proteins,​ which are contained in​ great quantities in​ pulses,​ and dried nuts,​ and animal proteins,​ which may be established from animal sources,​ like eggs,​ meat,​ fish,​ poultry,​ milk,​ and so on. the​ animal proteins are extra valuable,​ and hence vegetarians must contain adequate quantity of​ milk in​ their diet,​ so as​ to​ fulfill the​ requirements of​ animal proteins. the​ fats can also be had from two sources,​ namely,​ plants and animals. Both these are create to​ have identical energy value. But the​ animal fats,​ which are contained in​ butter,​ meat,​ egg,​ fish and poultry,​ are more valuable in​ as​ much as​ they are rich in​ vitamins a​ and D.

Numerous minerals,​ like Calcium,​ Magnesium,​ Phosphorus,​ Sodium,​ Iodine,​ Sulphur,​ etc.,​ are originated in​ the​ human body. They play an​ important role in​ controlling the​ biochemical activity going on​ in​ the​ body.Calcium and Phosphorous are basically required for the​ proper development of​ bones and teeth. Many disorders are caused due to​ deficiencies of​ various minerals,​ and hence,​ it​ is​ necessary to​ have them in​ sufficient amounts in​ one’s diet.

The vitamins,​ even though needed in​ very minute amounts,​ are often found to​ be lacking in​ diets. They are obtained from fruits,​ vegetables,​ milk,​ etc.,​ and are very intimately concerned with the​ maintenance of​ health and vigour of​ the​ body. Along with these nutrients,​ water is​ also needed in​ large amounts,​ because nearly 65% of​ the​ weight of​ our body is​ made by water. the​ body fluids,​ like saliva,​ the​ blood,​ the​ digestive juices,​ and endocrine secretions contain large amounts of​ water. Water helps in​ maintaining the​ body temperature within the​ normal range.

The mouth is​ the​ important organ for food. the​ food is​ cut into pieces with the​ teeth,​ and is​ ground into finer forms,​ and is​ moistened with saliva,​ so that it​ can be without difficulty passed down the​ throat. the​ pharynx is​ a​ part next to​ the​ mouth,​ where seven paths come and meet: two from the​ nose,​ one from the​ mouth,​ two from the​ ears,​ one going down to​ the​ lungs,​ and one to​ the​ stomach. the​ food masticated and moistened in​ the​ mouth passes through the​ pharynx,​ down this last path,​ made by the​ gullet or​ oesophagus,​ which leads eventually to​ the​ stomach. the​ food remains in​ the​ stomach for about two hours,​ and gets mixed with the​ Hydrochloric Acid and digestive juices secreted by the​ stomach wall. it​ then passes to​ the​ duodenum which has the​ shape of​ an​ inverted horse-shoe. Three digestive juices get mixed with it​ here,​ namely,​ the​ pancreatic juice (secreted by the​ glands called pancreas),​ the​ bile (produced in​ the​ liver),​ and the​ juice of​ the​ duodenum itself. as​ a​ result of​ the​ action of​ various digestive juices,​ the​ constituents of​ food,​ especially the​ fats,​ proteins and carbohydrates are broken down to​ simpler substances which can be assimilated in​ the​ body. the​ small intestines which are over twenty feet long,​ are responsible for absorption of​ the​ digested constituents of​ food. the​ remaining part goes to​ the​ large intestines (nearly five feet long),​ and is​ ultimately eliminated through the​ anus after absorbing water from it​ in​ the​ large intestines. the​ assimilated constituents of​ food are largely stored in​ the​ liver,​ and are supplied to​ the​ tissues,​ muscles,​ and all the​ parts of​ the​ body,​ through the​ agency of​ blood.
