Physiology kunye komzimba womntu. Le nkqubo emithanjeni

Inkqubo emithanjeni - ukuba yinxalenye yenkqubo sentliziyo, leyo zongeza kuyo. Iqhuba imisebenzi ebalulekileyo emzimbeni womntu impilo yawo kubalulekile ubomi yayo yesiqhelo. Nkovu iyahluka kwenye igazi nto ukugeleza isangqa eqhubekayo. intshukumo yakhe olucothayo kakhulu, ngenxa yokuba kufuneka ukuba zisebenze.

Interesting neqiniso! Kumaxesha amandulo, inkqubo emithanjeni kubonwa njengoko onefuthe ephambili senhliziyo yabantu. Sawo, nayo, ichaza iqela izifo ezehlela abantu.

Yintoni inkqubo emithanjeni?

Ngokutsho kwendlela ezakhiwe ngayo inkqubo emithanjeni yabantu okusaqhubekayo umzimba uphela. Oku kuquka:

• emithanjeni;
• iimpahla;
• iindawo;
• lymphatics kunye neziqu;
• amalungu emithanjeni.

Ngokutsho kwakhe, ulwelo iqukuqela kwizicwili - le nkovu, kwindawo engundoqo apho - kuba amanzi, iityuwa, iiprotheni, amafutha. nokubunjwa kwayo liyafana plasma yegazi, umzimba ubonelelo. Nkovu enemibala. Xa abantu, kuba iqulathe ukusuka kwiilitha 1 ukuya 2.

wenza njani nkovu Ukwakheka?

Nkovu owabumba kwenzeka ngale ndlela ilandelayo. Le emithanjeni igazi lwenzeka kwi-plasma wokucoca igazi. Ulwelo eliseleyo ngenxa yale coco ihanjiswa kulo isithuba extracellular. Ngaloo kwakhiwa lolwabo fluid, inxalenye yayo babuyela igazi; esinye isahlulo kuya emithanjeni nkovu. intshukumo kwayo kuxhomekeka yindibanisela izihlunu, indawo umzimba nokuphefumla.

Apha ezinjalo kunzima - komzimba womuntu. Inkqubo emithanjeni kunye storoenie isimo sawo babecinga ukuba nkcukacha zincinane. Qwalasela eli candelo omzimba womntu ngokweenkcukacha.

Ubume yenkqubo emithanjeni

emithanjeni emithanjeni - ityhubhu encinci ubukhulu ezahlukeneyo, abunaluthando inwebu, leyo uqala ongayaziyo. Bayeyona umchiza ngenxa interlacing-nye, labona postcapillaries ukuba ezakhiwe ezinkulu equlethe lwezivalo. Le valve tyhala nkovu kwicala elinye, ukuthintela intshukumo yayo umva.

Isilumkiso! Igama elithi "nkovu" ayichanekanga, kuba nkovu yi yimveliso endothelium kunye mezhendotelialnyh ungqameko, ixesha ngalinye nangokuhlaziya umzimba. Oogqirha bathi oku inkqubo nkovu.

Ngokutsho yesebe eziphilayo ebizwa ngokuba "komzimba womuntu", inkqubo emithanjeni liquka empahla akhiwa postcapillaries. I inkulu kubo ukulandela indlela imithambo yegazi, kwaye zibizwa ngokuba kubaqokeleli. Baya kuqokelela nkovu yemithombo ezinkulu - imilenze ephezulu nesezantsi, amalungu. Nohlulwe yangaphakathi (imi kufutshane imithambo yegazi) nangaphandle (ise inyama ongama). Kwakhona iimpahla zahlulwe afferent kunye efferent (ngokuxhomekeke flow nkovu ngokunxulumene kwiindawo nkovu).

Ukususela abaqokeleli akhiwa iziqu emithanjeni, eziguqulelwe kwi imibhobho.

nodes nkovu

Inkqubo emithanjeni yomntu (owakhiwe ixesha elide akazange ukunika le nxalenye ingqalelo yethu ngenxa emzimbeni) Kwakhona uye "abacoci" yayo. iindawo nkovu - ukuma encinane semilo setyhula okanye embhoxo ukuba ububanzi of malunga 2 cm Zinelungelo ithinti ezipinki-izimvi .. Bona ibekwe ecaleni iimpahla emithanjeni. Abantu abatsha ngabona iindawo nkovu ezi okweqanda imilo, yaye abadala, bona anaba ubude. Owona msebenzi wabo - into yokuhlambulula nkovu ukusuka izinto eziyityhefu ndifikile apho. iindawo nkovu ukudlala indima lokucoca, leyo uyazibambisa ubuthi "kukhupho" sele usule nkovu.

amalungu emithanjeni - a udakada, tonsils kunye thymus (leyo iqalisa lokufikisa). Owona msebenzi wabo - zinqanda intshayelelo kunye nophuhliso losuleleko emzimbeni.

Yiyiphi imisebenzi emzimbeni ethwele inkqubo emithanjeni?

Enye nenzululwazi olunzima kakhulu ubugocigoci ke komzimba womuntu. Inkqubo emithanjeni, abamisebenzi yabo ibaluleke kakhulu umzimba, wenza umsebenzi omkhulu.

Okokuqala, oko linoxanduva omzimba, andingowasemzimbeni, ukukhusela kuyo ukunxibelelana kwiintsholongwane. Kungenxa yoko le nto, ukuphendula kwii ka pathogen emzimbeni (usulelo intsholongwane) anda kwiindawo nkovu. Kuyinto zabo ebantwaneni ibonisa ubukho, yithini, isifo sephepha, nangona, ukongeza, kwiindawo nkovu Ekwandeni kunye nenani nezinye izifo. Zikhusela iqulathe amanyathelo ezimbini:

• Intsholongwane intshabalalo nge macrophage;
• imveliso lymphocyte.

Internet igazi. Le spleen lutshabalalisa iiseli ezibomvu zegazi ubulala zonke iintsholongwane kunye iintsholongwane ezifumaneka egazini. Iiseli Young ezibomvu ukuvelisa lomongo wethambo. Yokuhluza nkovu. Ukuba igazi magciwane, ngoko ke kwiindawo nkovu luhluzwa kubo. Kungenxa yesi sizathu, kwiimeko oogqirha Oncology olukrokrelwayo kuqala ujonge ukuba ubukho metastases nkovu node. Inkqubo emithanjeni yomntu (komzimba ngokufutshane kuxoxwa) kulo mzekelo ubonisa njani isifo kuye wonke umzimba.

Yayikukuphuphuma ulwelo esikule egazini. Plasma, ibekwe igazi engena iindonga isitya kwezinye iithishu. Udlula i iimpahla emithanjeni, ukuwuhlamba ndabuyela egazini. Loo ejikelezayo into eqhubekayo.

Izifo yenkqubo emithanjeni

Ngokutsho komzimba womuntu, inkqubo emithanjeni kubaluleke kakhulu ukuba impilo emzimbeni, kwaye oko kuya fail kunokubangela iingxaki ezinzulu.

Phakathi kwamaqela yezifo kwenkqubo emithanjeni ayinabantu:

• malformations;
• ukuphatheka;
• komtshiso oko;
• ithumba.

Enye iimpawu zokuqala zezi zifo - nkovu esiludumbo ukukhula kunye ukuncipha sifo. Ukwanda ukubila, ukudinwa, izigulane intloko ebuhlungu ukhathazekile, iqondo lobushushu nga kuvuswa. Vela nkovu nokudumba. Izifo nkovu iyingozi kakhulu ngoba emzimbeni kuqala ukuze yande abulale. Leyo lunyhasho umsebenzi wayo kuchaphazela onke amalungu kunye neenkqubo zomzimba.

Iindlela ngenxa yonyango ezimbi kwenkqubo emithanjeni kuxhomekeke ngqo kuhlobo sifo. Unyango inokuba nomahluko - ukusuka endala ukuba iphiramidi ebonisa unxibelelwano okanye iindlela zokusebenza.

Siyathemba ukuba abantu abanomdla komzimba womuntu, inkqubo emithanjeni (iifoto, ebonisa nzima ngayo le nxalenye yomzimba wethu, lucaciswa kule nqaku) kunye nemisebenzi yayo, wafunda lukhulu izinto ezintsha ezinomdla imvelo ephilayo. Indlela ukukugcina usempilweni?

Impilo yenkqubo emithanjeni

Okokuqala, oogqirha Siyaleza iliso impilo yabo kunye nokuthintela izitenxo kwisiqwenga zesisu, kuba ubhaptizo ungcoliseko umzimba uphela kwaye kuphazamisana nenkqubo emithanjeni. Akabi ukumelana nokungena ityhefu. Qaphela ukudla.

Kabini ngonyaka, yenza umyalezo. Le nkqubo ngempumelelo ibalekisa nkovu, kodwa ingakumbi rezultativen emithanjeni semibhobho yokuthanjiswa, nto leyo echaphazela ngqo nkovu. Ukuba awukwazi ndwendwela i therapist yokuthanjiswa, egeza, tipakani washcloth umzimba nkovu yangoku.

Lawula ubunzima bakho. Nkovu inovakalelo kakhulu utyebile. Ukugcina yokuphila asebenzayo kwaye inempilo!
