 alcohol, and ether. In dyeing it yields a fine purple- 

 red coloring-matter, and several other dyes of commer-

 . spiration (res-pe-ra'-shun) \j-espiratio : respirare, to 

 reathe again]. The inspiration and expiration of air 

 arough the lungs. In biology, the continuous inter- 

 hange between the gases of living organisms and the 

 ases of the medium in which they live, continuous 

 i aroughout life. This consists in all active cells in plants 

 ; f a constant absorption of the oxygen of the air into 

 le tissues, where it causes oxidation of the assimilated 

 ; ubstances and the release of carbon dioxid. The 

 lovements of protoplasm are dependent upon respi- 

 ltion. It is the opposite of assimilation. R., Ab- 

 iominal, respiration caused by the contraction of the 

 iiaphragm and the elasticity of the abdominal walls 

 tod viscera. It is more common in men than in 

 vomen. R., Aerial, respiration in which the respi- 

 atory membrane receives oxygen and is relieved of 

 arbon dioxid by means of atmospheric air. R., 

 Amphoric, a blowing respiration engendered in large 

 avitfes with firm walls. Its peculiar character is 

 lue to an echo from the walls of the cavity. R., 

 Aquatic, respiration in which the respiratory mem- 

 rane.the branchial mucosa(gills),the skin, etc. , receive 

 «ygen and are relieved of carbon dioxid by means of 

 ater. R., Artificial, artificial production of the 

 )rmal respirator}' movements. See Artificial Respi- 

 Uion. R., Biot's, periodic respirations without 

 iy variation in the extent of the individual respira- 

 •ns. It occurs normally during sleep. R., Blood, 

 e giving off of carbon dioxid and taking up of 

 ygen by the blood during its passage through the 

 ngs. The blood while passing through the capil- 

 ries gives up its oxygen to the tissues and takes up 

 rbon dioxid. R.. Blowing. See R., Bronchial. 

 '.., Branchial, respiration by means of gills or bran- 

 in aquatic animals. R., Bronchial, respira- 

 ' >n as heard over the trachea or bronchial tubes in 

 i< alth ; it is high in pitch, equal in inspiration and 

 f piration, blowing in character, especially the ex- 

 element, and is marked by a brief pause 

 tween inspiration and expiration. It is well 

 :ined only in case of pulmonary consolidation. 

 ., Broncho-cavernous, a form intermediate in char- 

 ter between bronchial and cavernous respiration. R., 

 "oncho-vesicular, respiration having the characters 

 both bronchial and vesicular respiration. It is 

 ard over areas of consolidation surrounded by 

 i tches of healthy lung-tissue. R., Buccal. See 

 reathing. R., Cavernous, a blowing respi- 

 lon of low pitch, circumscribed, alternating with 

 rgling, and deriving its chief character from the nature 

 the caviu in which -it is generated. R., Center of, 





RESPIRATION 



the nervous center regulating the act of respiration is 

 situated in the floor of the fourth ventricle near the 

 point of the calamus. It is automatic in its action. 

 R., Cerebral, respiration in which the lips are closed, 

 the cheeks distended, the nostrils dilate with each 

 expiration, which is attended with a puffing sound ; 

 the respirations are irregular. It is observed especi- 

 ally in typhus fever and in apoplexy. R., Cheyne- 

 Stokes, a peculiar type of breathing in which 

 there is a rhythmic increase of the respirations up to a 

 certain degree of rapidity, then gradually' decreasing 

 again to temporary cessation. This pause may be as 

 long as half a minute. This form of respiration is 

 most commonly seen in the late stages of tuberculous 

 meningitis, but it may also be noted in apoplexy, fatty 

 degeneration of the heart, and nephritis with uremia. 

 R., Clavicular, a form resorted to by singers and in 

 which the clavicle is brought into play in the respiratory 

 movements, the shoulders being elevated. R., Cogged 

 or Cogwheel. See R., Interrupted. R., Costal, respi- 

 ration in which the chest-movement predominates over 

 the diaphragmatic movement. It is seen especially in 

 women , and is supposed to be related to gestation or per- 

 haps partially to the mode of dress. R., Costo-inferior, 

 respiration in which the elevation and depression (respi- 

 ratory movements) are confined chiefly to the lower ribs. 

 It is best seen in dogs. R., Costo-superior, respiration 

 in which the respiratory movements involve chiefly the 

 upper ribs. It is most common in women. R., Cu- 

 taneous, the giving off of carbon dioxid and taking 

 up of oxygen through the skin. R., Diaphragmatic. 

 See R., Abdominal. R., Direct, respiration in which 

 the living substance of an organism, as an ameba, 

 takes oxygen directly from the surrounding medium 

 and returns carbon dioxid directly to it, no respiratory 

 blood being present. R., Divided, respiration in which 

 there exists a distinct interval between inspiration and 

 expiration. It is seen in emphysema as a result of the 

 distention of the air- vesicles and consequent reduction 

 in expelling force. R.. Exaggerated, an increase in 

 intensity, without alteration in character or rhythm of 

 the respiratory movements. R., External. See R., 

 Blood. R., Extrinsic (of F. Hcicitt), the inspiration 

 and immediate expiration of a gas, so that a portion 

 that has once been inspired is not inspired again. R., 

 Facial, a term applied to all the movements of the 

 face during inspiration and expiration. R., Feeble, 

 diminution in the intensity, without alteration in the 

 character or rhythm of the respiratory movements. 

 R., Fetal, the interchange of gases between the fetal 

 and the maternal blood through the medium of the pla- 

 centa. R., Forced, respiration induced by blowing 

 air into the lungs by means of a bellows, or in some 

 other way, as in physiologic experiments. R.. Harsh. 

 See R., Broncho-vesicular. R., Hissing, an increased 

 vesicular murmur causing a hissing sound. R., Hollow. 

 See R., Amphoric. R., Indeterminate, the most pro- 

 nounced vesicular grade of broncho-vesicular respira- 

 tion. R., Indirect, respiration in which the living sub- 

 stance of the organism, as in all the higher animals, 

 gets rid of carbon dioxid and obtains oxygen by means 

 of a circulating respiratory blood. R., Inner or Inter- 

 nal, the taking up of oxygen and giving off of carbon 

 dioxid by the body-elements for their own require- 

 ments. It occurs in man in the capillary system. R., 

 Interrupted, respiration in which either inspira- 

 tion or expiration is divided into two or more parts. 

 It is most often heard at the apex of the righi 

 lung, anteriorly. R., Intestinal, the interchange of 

 respiratory gases in the mucous membrane of the in- 

 testines. R., Intra-uterine, respiration by the fetus 

 before delivery. R., Intrinsic (of F. Hewitt), the
