Ngaba wakha wazibuza ukuba zingaphi izinto ezimangalisayo ezenzekayo emizimbeni yethu? Njengenethiwekhi yeendlela kwisixeko esikhulu, imizimba yethu inenkqubo yemithambo yegazi ethwala igazi kuyo yonke. Le nkqubo ibandakanya iindlela eziphambili (imithambo yegazi), iindlela ezincinci, kwaneendlela ezincinci kakhulu ezikhokelela emakhaya. Ezo ndlela zincinci zezo sizibiza ngokuba 'ziiCapillaries'. Ezi zezona zihambisa ioksijini kunye nezondlo kuyo yonke iseli emzimbeni wethu kwaye ziqokelela imveliso yenkunkuma apho. Ngoko ke namhlanje sithetha ngezi ntlobo zincinci, kodwa zibaluleke kakhulu zemithambo yegazi, 'iiCapillaries eziqhubekayo'.
Ngamafutshane, zithini ezi capillaries?
Khawuthelekelele u-odola into kwi-intanethi. Ilori enkulu iyizisa kwisixeko esikhulu, ize iveni encinci iyizise edolophini lakho, ekugqibeleni kufike umfana ohambisa impahla ngebhayisekile aze ayizise emnyango wakho. Yiyo le indlela igazi elijikeleza ngayo emzimbeni wethu. Imithambo yegazi emikhulu (imithambo yegazi) ethwala igazi elineoksijini esuka entliziyweni ifana neelori. Xa elo gazi lifikelela kwizitho zomzimba, liyahlukana libe yimithambo yegazi emincinci. Ekugqibeleni, ii-capillaries zezona mithambo yegazi mincinci ebonelela ngeoksijini kunye nezondlo kwiseli nganye. Kanye njengaloo mfana ohambisa impahla.
Iindonga zezi capillaries zenziwe ngohlobo oluthile lweseli olubizwa ngokuba 'zii-endothelial cells' . Ezi seli zidibene ngokusondeleyo kwaye zicwangciswe ngomgca oqhubekayo, yiyo loo nto igama elithi 'continuous'. Ezi zezona ntlobo zixhaphakileyo ze capillaries ezifumaneka emzimbeni wethu.
Ngaba kukho iintlobo zezi capillaries eziqhubekayo?
Ewe, kukho iintlobo ezimbini eziphambili. Umahluko phakathi kwazo bubungakanani bezithuba phakathi kweeseli ezenza iindonga. Masibone ukuba zeziphi.
| Uhlobo lwe-capillary | Inkcazo kunye nendawo |
|---|---|
| Ii-capillaries ezingatshixwanga rhoqo | Izikhewu phakathi kwezi seli zincinci kakhulu. Ngenxa yoku, ziingceba ezincinci kakhulu ezifana namanzi, iglucose, iihormones, kunye neegesi ezinokudlula kuzo. Njengesihluzo apho ucofa khona ikomityi yeti. Ezi zifumaneka kwinkqubo yethu yemithambo-luvo, ulusu, kunye nemiphunga . |
| Ii-capillaries ezihlala ziqinile | Ezi zinemingxuma emikhulu kancinci, ebizwa ngokuba yi-'fenestrations', phakathi kweeseli. Oku kuvumela izondlo kunye nezinye izinto ezisegazini ukuba zidlule ngokukhawuleza. Ezi zifumaneka kwizintso zethu, emathunjini amancinci, nakwiindlala ze-endocrine . |
Kukho olunye uhlobo olubizwa ngokuba yi-'sinusoidal capillaries'. Aziqhubeki, oko kuthetha ukuba kukho izithuba ezinkulu phakathi kweeseli. Ezi zifumaneka kwiindawo ezifana nesibindi, i-spleen, kunye ne-lymph nodes.
Ezi zinto zinceda njani amalungu omzimba wethu?
Le mithambo yegazi mincinci iyinxalenye ebalulekileyo yokusebenza kwamalungu amaninzi abalulekileyo emizimbeni yethu.
Ikhusela ingqondo
Ingqondo yethu sisitho esibuthathaka kakhulu. Ayinakungena kuyo nantoni na. Loo khuselo lubonelelwa yinkqubo ekhethekileyo yee-capillaries. Siyibiza ngokuba 'ngumqobo wegazi-ubuchopho' . Ifana neofisi yevisa yokungena kwilizwe. Ivumela kuphela izinto ezibalulekileyo ezifunekayo kwingqondo, njengeoksijini namanzi, ukuba zingene, kwaye ithintela iityhefu kunye neentsholongwane egazini ukuba zingangeni kwingqondo. Oku kwenziwe ngala ma-capillaries angenawo ulwelo esithethe ngawo ngaphambili.
Ukuzisa iihomoni kwindawo efanelekileyo
Iihomoni ziveliswa zii-endocrine glands emizimbeni yethu. Ezi homoni kufuneka ziye kwizitho ezifanelekileyo emzimbeni kwaye zilawule ukusebenza kwazo. Ezi capillaries zibonelela 'ngenkonzo yokuhambisa' ngokongeza ezo homoni egazini kwaye zizithwale ziye kwindawo eziyifunayo.
Inceda izintso
Ezi capillaries zidlala indima enkulu kwinkqubo apho izintso zethu zihluza igazi kwaye zivelise umchamo. Ngexesha lenkqubo yokucoca, ezi capillaries zikwanceda umzimba ukuba ufunxe kwakhona izinto ezifana namanzi kunye nesodium ezifunekayo.
Ukutshintshiselana kwegesi emiphungeni
Xa siphefumla, ioksijini esiyiphefumlayo yongezwa egazini, kwaye ikharbon diokside egazini ithunyelwa emiphungeni ukuze ikhutshwe ngezi capillaries zincinci emiphungeni.
Inceda ekugayweni kokutya.
Sifanele sigaye ukutya esikutyayo size sihambise izondlo kwiiseli zomzimba wethu. Kwisisu esincinci, ezi zondlo zifunxwa egazini ngee-capillaries. Emva koko, izondlo zisasazwa emzimbeni wonke.
Ziziphi izifo ezichaphazela la ma-capillaries?
Nangona zibalulekile, kukho iimeko ezahlukeneyo zempilo ezinokuchaphazela ezi capillaries zincinci. Ezinye zazo zisenokuba ziimeko zemfuza ezikhoyo ekuzalweni, ngelixa ezinye zinokuvela kamva.
| Iimeko zofuzo (zokuzalwa) | Iimeko ezingezizo ezemfuza (eziqala kamva) |
|---|---|
| Ukukhubazeka kwemithambo yegazi (AVM): Imeko apho imithambo yegazi kunye nemithambo yegazi ebuchotsheni okanye emgogodleni zidibana, zidlule kwii-capillaries. | Ii-capillaries eziphukileyo: Ngamanye amaxesha, ukukhwehlela okanye ukuhlanza kunokonakalisa imithambo yegazi emincinci engaphantsi kolusu. |
| I-telangiectasia ye-hemorrhagic hemorrhagic: Imeko ebangelwa kukukhula okungaqhelekanga kwemithambo yegazi enokubangela ukuba iqhume kwaye yophe ngokulula. | I-Capillary leak syndrome: Yimeko enzima apho uxinzelelo lwegazi luyehla ngequbuliso. Oku kunokufuna unyango kwi-ETU. |
| I-Microcephaly-capillary malformation syndrome: Ii-capillaries ezivulekileyo kubantwana abazelwe benentloko encinci. | I-Spider nevus: Imeko efana nesigcawu esinechaphaza elincinci embindini kunye nemithambo yegazi ebomvu ejikelezileyo. Iqhelekile kwiindawo ezifana nobuso nentamo. |
| Ukuwohloka kwe-macular: Ukonakala kombono ngenxa yokuvuza kwegazi kwi-capillaries yeliso. | I-Vasculitis: Ukudumba kwemithambo yegazi. Oku kunokubangela ukuba ii-capillaries zivaleke okanye ziqhume. |
Izazinzulu zisaphanda ukuba utshintsho ekusebenzeni kwezi capillaries luchaphazela na izifo ezifana nesifo sika-Alzheimer, istroke, kunye ne-vascular dementia .
Ngoko ke, singazigcina njani ii-capillaries zethu ziphilile?
Kusezandleni zethu ukunyamekela le mithambo yegazi mincinci, kodwa ixabiseke kakhulu. Akunyanzelekanga ukuba senze nantoni na ekhethekileyo ngaloo nto. Eyona nto iphambili kukugcina indlela yokuphila intle.
Izinto eziqhelekileyo onokuzenza:
- Kuphephe ukutshaya: Ukutshaya lutshaba olukhulu lwemithambo yegazi. Ngoko ke ukuba uyatshaya, zama ukuyeka.
- Yiba nobuchule bokwenza izinto ngokukhawuleza:Ukuzilolonga imihla ngemihla kulungile kakhulu ekujikelezeni kwegazi.
- Gcina ubunzima obusempilweni: Ukutyeba kakhulu kubeka uxinzelelo kwimithambo yegazi.
- Lawula ukusetyenziswa kotywala: Ukusela utywala kakhulu kuyingozi kwimithambo yegazi.
Kwakhona, ukuba uneemeko ezifana nesifo seswekile, uxinzelelo lwegazi oluphezulu , okanye i-cholesterol ephezulu , landela imiyalelo kagqirha wakho ngononophelo. Ukulawula ezi meko kubaluleke kakhulu kwimpilo ye-capillary.
Khusela ii-capillaries, ingakumbi ebusweni:
Ulusu lobuso bethu luthambile kakhulu, ngoko ke imiphunga yesikhumba apho inokonakala lula.
- Xa uhlamba ubuso bakho, buhlambe kancinci, ungabuhlikihli ngamandla.
- Qiniseka ukuba usebenzisa i -sunscreen efanelekileyo xa uphuma ngaphandle.
- Ukuba unesifo solusu esifana ne -rosacea , bona ugqirha uze ufumane unyango olufanelekileyo.
Ngokunyamekela ezi zinto, ungagcina la malungu omzimba wethu amancinci kodwa ayimfuneko, ii-capillaries, esempilweni. Ukuba uneengxaki okanye amathandabuzo ngale nto, ungaze ungathandabuzi ukuthetha nogqirha wakho wosapho.
Umyalezo Wokuya Ekhaya
- Ii-capillaries zezona mithambo yegazi mincinci emzimbeni wethu. Zezona zithwala ioksijini kunye nezondlo kuzo zonke iiseli zethu.
- Ii-capillaries eziqhubekayo zezona zixhaphakileyo. Iiseli zazo ziqhagamshelwe ngokuqinileyo.
- Umqobo wegazi nobuchopho, okhusela ubuchopho, wenziwe ngala ma-capillaries.
- Izinto ezinje ngokutshaya, imikhwa yokutya engafanelekanga, kunye nokungenzi nto zinokuchaphazela kakubi impilo yee-capillaries.
- Singayikhusela le nkqubo yemithambo yegazi exabisekileyo ngokugcina indlela yokuphila esempilweni nokulawula izifo ezifana nesifo seswekile kunye noxinzelelo lwegazi oluphezulu.
