Isiqondiso Humoral nezinqubo zokuphila

Evolution kuholela ukubonakaliswa ezihlukahlukene izinguquko emzimbeni eziphilayo, okuyinto eyabasiza ukuba bajwayele ukuba izimo zemvelo ukuze usinde kuleli zwe. Uma sikhuluma izinguquko esinazo emqondweni hhayi kuphela izici zangaphandle, izinguquko yangaphakathi emzimbeni kubaluleke ngisho ngokwezinga elikhulu. Okokuqala, kuhlobene izinqubo zokuphila yimuphi umzimba. Ngo kusaqalwa kwemvelo waqala ukuthatha ukuma isiqondiso humoral, njengoba enye yalezi izindlela nezinqubo.

Inani lawo ngokwanele ezinkulu ngoba isidalwa esiphilayo, ngoba ivumela ukuba aqondise ezihlukahlukene izinqubo yezinto eziphilayo futhi amakhemikhali ngu ketshezi. It okungukuthi lo msebenzi wenziwa humoral isiqondiso. Njengoba medium liquid izenzo igazi, lymph, izicubu uketshezi ezihlukahlukene, njengoba ibalulekile emzimbeni futhi ngokuyinhloko bakha ingxenye enkulu-ke. Humoral isiqondiso okungukuthi kungenzeka sibonga yokuthi amaseli, izicubu izitho zabo ukuphila secrete ezihlukahlukene eziphila abakhuthele izinto. Lezi zihlanganisa ngokuyinhloko, amahomoni metabolites, kodwa futhi kukhona ezinye izinhlobo.

isiqondiso Humoral e abantu

Onjalo nqubo yaqala ukuvela izidalwa eziphilayo isikhathi eside, butholakala eziningi, kodwa has umehluko ezithile kuye ngokuthi ifomu ethize. Ikakhulukazi umuntu, kanye ezinye izinhlobo zezilwane eziyinkimbinkimbi kakhulu: lezi zinqubo angaphansi isiqondiso sezinzwa. isiqondiso Ngethukile humoral ndawonye bakha ukusebenza uhlelo olulodwa. Igama layo yesayensi isiqondiso neurohumoral, futhi lafundvwako njengoba umthetho, kuphela kuleli fomu.

Phakathi umzimba secrete imikhiqizo ethile ethinta izitho effector nezinzwa, emsipheni izikhungo. Ngakho humoral noma reflex kubangelwa ukusabela ezithile ezidingekayo ekusebenzeni umzimba evamile.

Uma sicabanga ngesibonelo ukusabela komzimba womuntu ezinjalo, ezinye zazo uqale ukusebenza lapho udinga ukubuyisela imisebenzi ebalulekile. Phakathi umsebenzi ngesivinini umzimba, ophilisayo kwenhliziyo kanye ukuphefumula. Umthwalo imisipha kuvusa isidingo kusheshiswe ukushaya kwenhliziyo, ukuze abanikeze umoya-mpilo. Lokhu-ke kuholela yokuthi igazi kuba kakhulu CO2, kodwa ukuze ayibulale owadingayo ukuze ube ukuphefumula njalo - ngoba umzimba, elikhishiwe kwezinye izinguqulo yokushodelwa umoya futhi kuqeda-carbon dioxide. Lesi isibonelo sesimiso somthetho humoral.

isilawuli sezinzwa

Kulokhu osekushiwo, kuyacaca ukuthi lezi zinqubo kubalulekile ukuze umzimba athuthukile kakhulu futhi zitholakala yonke indawo. Kubantu, bonke exhunywe ohlelweni olulodwa neurohumoral, ngoba iyiphi ukuphendula kubangelwa ezinzwa amaza ngocansi ngqo amakhemikhali - neurotransmitters. Ngesikhathi esifanayo ehilelekile izinqubo ezinjalo kanye nezinye izinto, kuhlanganise ama-hormone. Cabanga ukusebenza kohlelo ngaphandle isixhumanisi olulodwa engenakwenzeka. Kuyadingeka ukuba acabangele yokuthi ukulawulwa humoral imisebenzi umzimba Kwenziwa njalo, kodwa ngeke ayithathe indawo embulungeni yonke.

Ukuqalisa izinqubo ezinjalo kufanele inake wonke izici uketshezi lomzimba. Ikakhulukazi, umsebenzi wabo yemvelo luncike okuqukethwe izici ezihlukahlukene kuzo - adrenalin, catecholamines, histamine, acetylcholine, serotonin, ama-enzyme ehlukahlukene inhibitor, kanye nabanye abaningi. Ngakho, ebhekisela izinqubo zomthetho letentiwako ngosizo lolu ketshezi, kubalulekile ukuba acabangele Ukwakheka kwabo.
