EXCRETORY SYSTEM AND PRANAYAMA

THE IMPORTANT PARTS OF THE EXCRETORY SYSTEM ARE LUNGS,LARGE INTESTINE,KIDNEYS,SKIN ETC. IN THE BODY,CARBON DIOXIDE IS FORMED ALL THE TIME. IN THE SAME WAY, THE EXCRETORY PRODUCTS ARE CONTINUOUSLY EXPELLED FROM THE BODY VIA THE URINE, FAECES,SWEAT AND EXHALED AIR. THE LAYERS OF INNUMERABLE AIR SACS AND THE AREA OF THE BLOOD CAPILLARIES SURROUNDING THEM ARE SO VAST THAT THEY CAN EXPEL CARBON DIOXIDE AND PROVIDE SUFFFICIENT OXYGEN TO THE BODY AND BRAIN. THEIR AREA IS SO VAST THAT,IN COMPARISON,THE AREA OF THE SKIN IS VERY SMALL. ALONGWITH MAN’S INTELLECTUAL ADVANCEMENT, HIS NEED FOR OXYGEN HAS INCREASED. DUE TO THIS, DURING THE PROCESS OF EVOLUTION, THE BREATHING THROUGH THE SKIN MUST HAVE BECOME LESS AND LESS AND THE DEVELOPMENT OF THE LUNGS MUST HAVE BECOME MORE AND MORE TO BECOME THE PRESENT-DAY RESPIRATORY SYSTEM.

DUE TO THE DISCIPLINED, RHYTHMIC AND PROPORTIONAL POORAKA AND RECHAKA IN PRANAYAMA,THERE ARE RHYTHMIC CONTRACTIONS AND EXPANSIONS OF THE BRONCHI,BRONCHIOLES AND AIR-SACS. THESE GIVE THEM THE HABIT OF SYSTEMATIC BREATHING SO THAT, AT OTHER TIMES ALSO,BREATHING CONTINUES IN AN ORDERLY AND BETTER WAY AND THE EXPULSION OF CARBONDIOXIDE,OTHER POISONOUS GASES AND WASTE MATERIAL FROM THE BODY BECOMES EASY. ALSO,IN PRANAYAMA,FULL USE IS MADE OF THE EXTRA RESERVE BREATHING CAPACITY. ONLY DUE TO THE CONSTANT USE OF THIS CAPACITY,IT IS READILY AVAILABE FOR ANY WORK AT ANYTIME,WHENEVER IT IS NEEDED.HENCE,THE RESPIRATORY SYSTEM CAN NOT ONLY FUNCTION IN NORMAL LIFE BUT IS EVER-READY TO SUCCESSFULLY FACE EVEN VERY CRUCIAL SITUATIONS.
IN POORAKA, THE AIR SACS ARE COMPLETELY FILLED WITH AIR. IN KUMBHAK THEY ASSUME STHE ‘AIR-FILLED’ SPACES, LIKE BALOONS AND SUSTAIN THE SAME UPTO THE END OF THE KUMBHAKA,AS PER THEIR CAPACITIES. IN RECHAKA,THE MOVEMENTS ARE PERFORMED LIKE THE ‘PAYMENT THROUGH THE BUCKET’ACTION [IN BOMBAY AND OTHER BIG CITIES,THOSE STAYING ON THE 2ND AND 3RD FLOORS MAKE TRANSACTIONS OF TAKING MATERIALS [LIKE VEGETABLES ETC] AND PAYING MONEY THROUGH BASKETS WHICH ARE LOWERED AND RAISED WITH THE HELP OF THE ROPES TIED TO THEM. WHILE LOWERING THE BASKET IT HAS TO BE LOWERED VERY SLOWLY],WHILE RELAXING THE MUSCLES,IF SUCH CONTROLLED AND SLOW MOVEMENTS ARE THERE,THEN THESE ARE CALLED’ PAYING THROUGH THE BUCKET ACTION’.THESE MMOVEMENTS BRING FLEXIBILITY,FIRMNESS AND MUSCLE TONE TO THE MUSCLES AND,DUE TO THIS,THEIR MINUTE AND DELICATE COVERINGS[LAYERS]ALSO BECOME FLEXIBLE AND FULL OF TONE. DUE TO SCH CONTROLLED AND DISCIPLINED CONTRACTIONS AND EXPANSIONS,THE UNDESIRABLE SIDE EFFECT SUCH AS EXCESSIVE EXPANSION AND INFLAMMATION OF AIR-SACS[EMPHYSEMA] WHICH OCCURS IN EXERCISES DONE IN A COMPETITIVE SPIRIT[ESPECIALLY,WEIGHT LIFTING,DOING STRENUOUS WORK,FAST RUNNING ETC.] DO NOT OCCUR IN PRANAYAMA. ON THE CONTRARY, THESE CONDITONS WHICH CAN OCCUR IN EXERCISES CAN BE AVOIDED BY THE PRACTICE OF PRANAYAMA
