Wakambozvibvunza here kuti zvinhu zvingani zvinoshamisa zvinoitika mukati memiviri yedu? Kungofanana nemigwagwa iri muguta guru, miviri yedu ine nzira yemitsipa yeropa inotakura ropa mukati mayo. Iyi nzira inosanganisira migwagwa mikuru (tsinga), nzira diki, uye kunyange migwagwa midiki inoenda kudzimba. Migwagwa midiki iyoyo ndiyo yatinodaidza kuti 'Capillaries'. Idzi ndidzo dzinoendesa okisijeni nezvinovaka muviri kumasero ese ari mumuviri wedu uye dzinounganidza marara ikoko. Saka nhasi tiri kutaura nezvemhando idzi diki, asi dzakakosha kwazvo dzemitsipa yeropa, 'Continuous Capillaries'.
Zvichitaurwa zviri nyore, chii chinonzi capillaries idzi?
Fungidzira watenga chimwe chinhu online. Rori hombe rinouya nacho kuguta guru, mota diki rinouya nacho kuguta rako, uye pakupedzisira mukomana wekutakura nebhasikoro anouya oendesa pakeji pasuo rako. Ndizvo zvinotenderera ropa mumuviri wedu. Mitsipa mikuru yeropa (tsinga) inotakura ropa rakawanda neokisijeni kubva pamoyo yakafanana nemarori. Kana ropa iroro rasvika munhengo dzemuviri, rinopatsanuka kuita mitsipa midiki. Pakupedzisira, mitsipa midiki yeropa inopa okisijeni nezvinovaka muviri kumasero ese. Sezvakaita mukomana wekutakura.
Madziro emakapillari aya anoumbwa nerudzi rwakakosha rwesero rinonzi 'endothelial cells' . Masero aya akabatana zvakanyanya uye akarongwa mumutsara unoenderera mberi, saka zita rekuti 'continuous'. Aya ndiwo marudzi emakapillari anowanikwa mumuviri wedu.
Kune mhando dzema capillaries aya anoenderera mberi here?
Ehe, kune mhando mbiri huru. Musiyano uripo pakati padzo ndewehukuru hwemipata iri pakati pemasero anoumba madziro. Ngationei kuti ndeapi.
| Rudzi rwe capillary | Tsananguro nenzvimbo |
|---|---|
| Mapapillari asina kuvharwa anoenderera mberi | Maburi ari pakati pemasero aya madiki kwazvo. Nekuda kweizvi, zvidimbu zvidiki chete zvakaita semvura, glucose, mahormone, uye magasi zvinogona kupfuura nepakati pazvo. Sesefa yaunosvina kapu yetii. Izvi zvinowanikwa mutsinga dzedu, ganda, nemapapu . |
| Ma capillaries anoenderera mberi akapfava | Aya ane maburi akakura zvishoma, anonzi 'fenestrations', pakati pemasero. Izvi zvinoita kuti zvinovaka muviri nezvimwe zvinhu zviri muropa zvipfuure nekukurumidza. Izvi zvinowanikwa muitsvo dzedu, muura hudiki, uye mumagland e endocrine . |
Kune rumwe rudzi runonzi 'sinusoidal capillaries'. Hadzisi dzinoenderera mberi, zvichireva kuti pane mipata yakakura pakati pemasero. Izvi zvinowanikwa munzvimbo dzakadai sechiropa, spleen, uye lymph nodes.
Izvi zvinobatsira sei nhengo dziri mumuviri wedu?
Mitsipa midiki iyi yeropa chinhu chakakosha pakushanda kwenhengo dzakawanda dzinokosha mumuviri wedu.
Inodzivirira uropi
Uropi hwedu inhengo inonzwisisika zvikuru. Hahugoni kupindwa nechero chinhu. Dziviriro iyoyo inopihwa nehurongwa hwakakosha hwe capillaries. Tinoidaidza kuti 'blood-brain barrier' . Zvakafanana nehofisi yevisa yekupinda munyika. Inongobvumira zvinhu zvakakosha zvinodiwa neuropi, senge oxygen nemvura, kuti zvipinde, uye inodzivirira chepfu nehutachiona muropa kuti zvisapinde muuropi. Izvi zvinoumbwa ne capillaries dzisina fenestrated dzatakambotaura nezvadzo.
Kuunza mahormone panzvimbo chaiyo
Mahormone anogadzirwa nemasero emudumbu ari mumuviri wedu. Mahormone aya anofanira kuenda kunhengo dzakakodzera mumuviri uye kudzora mashandiro adzo. Ma capillaries aya anopa 'basa rekutumira' nekuwedzera mahormone iwayo muropa uye kutakura kuenda kunzvimbo yaunoda.
Inobatsira itsvo
Ma capillaries aya anoita basa guru mukuita kuti itsvo dzedu dzisefe ropa uye dzigadzire weti. Munguva yekusefa, ma capillaries aya anobatsirawo muviri kutora zvinhu zvakaita semvura ne sodium yaunoda.
Kuchinjana kwegasi mumapapu
Patinofema, okisijeni yatinofema inowedzerwa muropa, uye kabhoni dhayokisaidhi iri muropa inoendeswa kumapapu kuti ibudiswe kuburikidza neaya madiki diki ari mumapapu.
Inobatsira kugaya chikafu.
Tinofanira kugaya chikafu chatinodya uye kuendesa zvinovaka muviri kumasero emuviri wedu. Muura hudiki, zvinovaka muviri izvi zvinopinda muropa kuburikidza netsinga dzeropa. Zvadaro, zvinovaka muviri zvinopararira mumuviri wese.
Ndezvipi zvirwere zvinokanganisa mitsipa iyi yeropa?
Pasinei nekukosha kwazvo, kune zvirwere zvakasiyana-siyana zvinogona kukanganisa mitsipa midiki iyi. Zvimwe zvacho zvinogona kunge zviri zvirwere zvemajini zviripo pakuzvarwa, nepo zvimwe zvinogona kukura gare gare.
| Mamiriro ekuberekwa (emajini) | Zvirwere zvisiri zvemajini (zvinotanga gare gare) |
|---|---|
| Kukanganisika kwetsinga dzeropa (AVM): Mamiriro ezvinhu apo tsinga dzeropa netsinga dzemuuropi kana dzemusana zvinosangana, zvichipfuura ma capillaries. | Matsipa eropa akatyoka: Dzimwe nguva, kukosora kana kurutsa kunogona kukuvadza tsinga diki dzeropa dziri pasi peganda. |
| Kubuda ropa muropa kwenhaka: Chirwere chinokonzerwa nekukura kwetsinga dzeropa zvisina kujairika izvo zvinogona kuita kuti dziputike nekubuda ropa zviri nyore. | Capillary leak syndrome: Chirwere chakakomba apo BP inodzikira kamwe kamwe. Izvi zvingada kurapwa muETU. |
| Microcephaly-capillary malformation syndrome: Kukura kwemasero eropa muvana vanoberekwa nemusoro mudiki. | Spider nevus: Chirwere chinotaridzika sedandemutande rine kadonhwe kadiki pakati netsinga dzeropa dzvuku dzakaripoteredza. Chinowanzoitika munzvimbo dzakadai sekumeso nemutsipa. |
| Kuora kwemaziso: Kukuvadzwa kwekuona nekuda kwekubuda kweropa kubva mutsinga dzemaziso. | Vasculitis: Kuzvimba kwetsinga dzeropa. Izvi zvinogona kukonzera kuti matsipa eropa avharidzike kana kuputika. |
Masayendisiti achiri kuongorora kana shanduko mukushanda kwema capillaries aya dzichikanganisa zvirwere zvakaita sechirwere cheAlzheimer, sitiroko, uye vascular dementia .
Saka, tingachengetedza sei mitsipa yedu yeropa iine hutano?
Zviri mumaoko edu kutarisira tsinga idzi diki dzeropa, asi dzinokosha zvikuru. Hatifanirwe kuita chero chinhu chakakosha paizvozvo. Chinhu chikuru ndechekugara tichirarama hupenyu hwakanaka.
Zvinhu zvakajairika zvaunogona kuita:
- Dzivisa kusvuta: Kusvuta ndiwo muvengi mukuru wetsinga dzeropa. Saka kana ukasvuta, edza kurega.
- Iva nepfungwa dzinoshanda:Kurovedza muviri zuva nezuva kwakanakira kufamba kweropa.
- Ramba uine huremu hwakanaka: Kufuta kunoisa dambudziko patsinga dzeropa.
- Dzora kunwa doro zvakanyanya: Kunwa doro zvakanyanya kunokuvadza mitsipa yeropa.
Uyewo, kana uine zvirwere zvakaita sechirwere cheshuga, BP yakakwira , kana cholesterol yakakwira , tevera mirairo yachiremba wako nokungwarira. Kudzora zvirwere izvi kwakakosha zvikuru pahutano hwemitsipa yeropa.
Dzivirira ma capillaries, kunyanya pachiso:
Ganda riri pachiso chedu rakapfava zvikuru, saka mitsipa yeropa iripo inogona kukuvara zviri nyore.
- Paunenge uchigeza kumeso kwako, geza zvinyoro nyoro, usingakwize zvine simba.
- Iva nechokwadi chekushandisa mafuta akanaka ekudzivirira zuva paunenge uchienda panze.
- Kana uine chirwere cheganda chakadai serosacea , enda kuna chiremba wowana kurapwa kwakakodzera.
Nekutarisira zvinhu izvi, unogona kuchengetedza masero madiki aya emuviri wedu, ayo ari eropa, aine hutano. Kana uine matambudziko kana kusava nechokwadi panyaya iyi, usambozeza kutaura nachiremba wemhuri yako.
Mharidzo Yekuenda Nayo Kumba
- Ma capillaries ndiwo tsinga diki dzeropa mumuviri wedu. Ndidzo dzinotakura okisijeni nezvinovaka muviri kumasero edu ese.
- Ma capillaries anoenderera mberi ndiwo anonyanya kuwanikwa. Masero avo akabatana zvakasimba.
- Chidziviriro cheropa neuropi, chinodzivirira uropi, chakagadzirwa nema capillaries aya.
- Zvinhu zvakaita sekusvuta, kudya zvisina kunaka, uye kusaita maekisesaizi zvinogona kukanganisa hutano hwetsinga dzeropa.
- Tinogona kuchengetedza hurongwa uhwu hunokosha hwetsinga dzeropa nekurarama hupenyu hune hutano uye kudzora zvirwere zvakaita sechirwere cheshuga neBP.
