Show THE HUMAN MACHINE ITNE MANS BODY AND ITS WONDERS OF mechanical DEVICES I 1 J manyo of le the inventions of 0 the day are art on the ho clevell ami and deviben in nature a patent oillie I 1 so fearfully and wonderfully ig is tho tile human buman body made that scientists iro aro beginning to realize that many of the inventions of tho the day are infringe ments on oil tia natures tures patent office A good deal of trouble and worry in the tile past could have been avoided had bad inventors made a careful study of the devices employed in making these hu lin man bodies of oura ours the useful things they are the principles of the block and pulley or the tackle could havo have been discovered ages before had tha flies feea of natures patent office been ransacked for there are several complete pulleys in the body notably the one which moves the eyeball inward toward tho tile dioso I 1 engineers made exhaustive tests and experiments before they discovered that a hollow shaft t or rod pf af iron or steel is about twice as strong as a solid one yet nature had patented this device in our bones since the birth of adam and eve and every important bone is practically constructed on this principle the ball and socket of the hip bones were the forerunners of the modern ball bear hearings lugs and it waa the first automatic oiling machine used in the world the value of air pressure and a vacuum was unknown to man until the last century but every one of us carried the secret in the air tight hip joint which nature had bad assigned to lessen the muscular effort to hold our legs upright in position engineers have made wonderful progress s in developing compound sueon suction on and tind circular pumps but all of the principles contain edlin them are found in the heart and this little pumping machine is still without a rival in the MID mechanical chanilal ch anical world I 1 the principles principle of the safety valve for steam engines are not so new as they seem our human bodies carry with them the first automatic safety valves ever designed there are upward of 25 of them we call them by the common name of sweat glands each such little gland has a safety valve which lets off beat from the body when it gets beyond d a safe oaf e temperature wo we cannot stand a rise of more than 8 to 10 degrees of temperature pera ture and live it therefore the safety valves were closed for twenty four hours death would supervene adams apple was the first stora storage e cistern ever built and it works with automatic regularity through health and sickness it is a most important organ of the body althou although gb for centuries tt it was considered a superfluous attachment it regulates regulated the flow of blood between the heart and the brain when it ceases to operate somebody dies of apoplexy or a rush of blood to the brain when the heart sends up too much blood to the head the adams apple ap pp le steps in to check the flow and store it up for future emergencies it the heart is temporarily weakened or put out of good running order the blood stored in this cistern is given up and sent to the brain the perfect working of this little device is apparent when we coris consider lder how comparatively few die of rush of blood to the brain or from a deficiency of supply the eye has a score of small inventions worthy of recording the ear car nearly as many more moro and the vital organs an equal number thero there is the liver with its quarantine station let any poisons enter our systems with faoa and they are immediately neld up at nt this quarantine station and destroyed by a secret process it Is only when poisons enter in large quantities that the station cannot handle them but the stomach operates cooperates co with the liver and intercepts intercept a some of the poisons there arc are small machines there which aich manufacture minute quantities of hydrochloric acid field from the salts eaten this acid Is made in exact proportion to the tile amount of food consumed and suf flees to destroy the microbes mic robes which we swallow but there is even a third quarantine station located in the mouth millions illions Af of microbes mic robes are destroyed in lit the mouth dally daily by the juices juice elaborated there for this very tory purpose it if it was not for these three quarantine stations working contina bously night and day we should be killed off by microbes mic robes within an hour after eating a meal in the car there is a little device which might have been the original of our modern compressed air inventions the ulm delicate drum of the car must have an RD equal pressure from the outside and inside to receive and transmit the sound vibrations to make this possible the ous eustachian tube was devised its function Is to regulate the air pressure inside tile ear let it fall to work an and d one becomes stone deaf in the bones of the head there are many little channels hollowed out which are called the tile semicircular canals these bait Is are filled with fluid lymph for centuries no one could understand der stand their meaning some soma physicians considered them of no uso this tendency to belittle organs lu in the hur human body whose functions could not bo be explained has hits characterized mort than one generation of savants savanis sa now heso peculiar semicircular canals are known to be wonderful little devices to adaist us its in keeping our balance they net act a good deal as the ballast does on a ship or more prop properly efly speaking like the fluid in a spirit level the brain keeps an eye on this spirit level and 19 1 iliade conscious of the blodys relative position the fluid hows flows back and forth in the canals and when we get got it at a dangerous daneo roua angle the brain knows it new now york tribune |
