Neuro-humoral system. Ulawulo nokuphefumla kunye neempawu zayo.

Emzimbeni womntu lilawula zonke iinkqubo ebalulekileyo. Nature inikeza iindlela ezimbini zisetyenziselwa le njongo - a Wayesoyika humoral. Ke uncedo Kukho nokulawula nokuphefumla.

Ukuphefumla - inkqubo ebalulekileyo emzimbeni wethu. Isixokelelwano sokuphefumla ubonelela ngokutshintshiselana CO2 kunye O2 phakathi eziphilayo kunye nokusingqongileyo lwangaphandle. Oku kubaluleke kakhulu imisebenzi zokulawula luvo eziliqela CNS, apho zifumaneka kwiindawo ezininzi zobuchopho kwaye ezidityanisiweyo baneembono ngokubanzi of "iziko yokuphefumla". Ubethwa kwizinto Wayesoyika humoral, ngaloo ndlela kukho nokuphefumla isixhobo efanelekileyo umsebenzi iimeko zokusingqongileyo ukuba iguquka.

ulawulo ukoyika eziphefumlayo

Izakhiwo ukuba zibalulekile ukuvela izingqisho nokuphefumla afunyanwa okokuqala kwi Oblongata Medulla. intshabalalo yayo kukhokelela ekubeni abanjwe sokuphefumla. Le neuron libandakanyeka ngqo ukulawulwa nokuphefumla. Kungenxa yoko le nto iziko sokuphefumla na umsebenzi rhoqo. Kuyo kukho pulses excitation zesingqisho kunye zibhalwe umsebenzi ezinesingqi. Ngaphezu koko, la ukusuka kwiziko ngokusebenzisa luvo centrifugal zisulelane kwizihlunu bokuphefumla uvalo. Ngaloo alternation abathwele expiratory kwaye inspiratory emzimbeni wethu. Xa nqgo buhlungu, ukukhuthazwa igazi iinqanawa receptor inkanuko okanye ngokwamalungu kwisisu, utshintsho sokuphefumla lwenzeka reflex ngokupheleleyo.

Ngoko ke, ukuba ukurhogele imisi ammonia, kuya kuba receptors axakane mucosal ngeempumlo, oko kungabangela ukulibaziseka yenkqubo zokuphefumla reflex. Oku ukukhusela umzimba, okusebenzayo ukukhusela imiphunga berhasi yingozi. Ulawulo nokuphefumla kwenzeka xa iintshukumisa luvo evela kwizihlunu bokuphefumla receptors ibekwe emiphungeni ngokwabo. Ukusuka kwezi la mandla kwaye kuxhomekeke ubunzulu inhalation kunye nomphunga.

Ulawulo umoya kunceda umzimba ukuziqhelanisa nolu tshintsho zokusingqongileyo, ezifana zazibambe umoya wakho, umntu unako ukutshintsha rhythm yakhe kunye nobunzulu. Iimbaleki na isiphumo neuron ichaza utshintsho prelaunch e ukuphefumla, intliziyo eyonyukileyo kunye groove yayo phambi kokuba khuphiswano.

ulawulo Humoral of ukuphefumla.

Kwi iziko sokuphefumla luchaphazela umchiza ukwakhiwa igazi, oko kukuthi lakhiwe igesi. Oluhlala egazini, icarbon dioxide receptors okukruqulayo sibuphethe ngezitya yegazi nadlulisela igazi entloko, waza wajika ngokusekelwe zezinto iziko sokuphefumla. Nomphumela ofanayo, kunye nezinye iimveliso kunye iasidi, abhalisela egazini, ezifana lactic acid. umxholo lwalo ukunyuka igazi ngexesha umsebenzi dystrophy. Le ntsabelo yeziko nokuphefumla ukutshintsha imeko eziphilayo ngenxa yempembelelo yokusingqongileyo lwangaphandle kwenzeka kweso, kumcimbi lemizuzwana. Mhlawumbi, ngoko umzimba wethu ukhathazekile imeko yempilo yethu kwaye ulumkisa ingozi elizayo okanye esondelayo. ummiselo Humoral kungenziwa Yayikufanele ngokuba le ndlela yamandulo yokuxhulumana iiseli imizimba yethu.

Kwakhona, imisebenzi eyimfuneko emzimbeni wethu zilawulwa yi iihomoni. Iyasebenza kakhulu kwaye ke izinto zomzimba kuyimfuneko ukuba ziveliswa kwamadlala yonyango. iiseli Secretory glands ngokudibana wayo komhlaba kunye Imithambo yegazi. Kungenxa yoko le iihomoni Ngena egazini ngokukhawuleza. isenzo sabo emzimbeni kakhulu.

Njengoko ubona, kunye nolawulo Wayesoyika humoral zibaluleke gqitha umzimba uphela, kungekhona nje isixokelelwano sokuphefumla.
