Reka twige ku mitsi y'amaraso iri mu mubiri wacu.

Ese wigeze wibaza uburyo amaraso agenda mu mibiri yacu? Imibiri yacu igizwe n'urusobe rw'imihanda mito, nk'imiyoboro itwara amaraso. Iyi miyoboro y'amaraso tuyita. Iyi ni yo itwara amaraso ava mu mutima wacu akayajyana mu bice byose by'umubiri wacu akayagarura mu mutima wacu. Iyi miyoboro y'amaraso ni nk'intumwa z'ingenzi zituma imibiri yacu ikomeza kubaho.

Imitsi y'amaraso ni iki? Ubwoko bwayo ni ubuhe?

Mu magambo make, imiyoboro y'amaraso ni sisitemu y'imiyoboro mito itwara amaraso mu mubiri wawe. Ni nk'imiyoboro itwara amazi, ariko itwara amaraso atanga ubuzima. Iyi sisitemu ni nk'uruziga rufunganye; rutangirira ku mutima wawe, rugenda mu mubiri wawe wose, hanyuma rukagaruka mu mutima wawe. Umutima wawe n'iyi miyoboro y'amaraso ni byo bigize sisitemu yawe y'amaraso . Tekereza, hari imiyoboro y'amaraso igera ku birometero 60.000 mu mibiri yacu! Ni uko uburebure bwabyo, sibyo?

Hari ubwoko butatu bw'ingenzi bw'imitsi itwara amaraso. Reka turebere hamwe ibyo ari byo:

• Imitsi : Iyi ni imiyoboro miremire kandi ikomeye itwara amaraso meza kandi afite ogisijeni ava mu mutima ajya mu mubiri wose. Iyi mitsi ni nk'inzira zigana mu mibiri yacu. Irakomeye cyane kandi ifite inkuta nini kuko igomba gutwara amaraso umutima utera ku muvuduko mwinshi.
• Imitsi : Iyi itwara amaraso adahumeka neza kandi adahumeka neza ava mu bice bitandukanye by'umubiri akayajyana mu mutima. Imitsi imeze nk'imitsi mito y'amaraso. Ikiyigira idasanzwe ni uko ifite uburyo bw'udutsi duto imbere muri yo kugira ngo tubuze amaraso gutembera inyuma.
• Kapilari : Iyi ni imitsi mito y'amaraso mu mubiri. By'umwihariko, ni yo ihuza imitsi n'imitsi. Ifite inkuta nto cyane, bityo biroroshye cyane ko ogisijeni, intungamubiri, dioxyde de carbone , n'imyanda yinjira mu maraso no kuyasohokamo.

Bashiki bato b'imitsi: arteriole

Uko imitsi ikwirakwira mu mubiri wose, irakura ikagera mu mashami mato n'ato. Nk'uko amashami y'ishami rinini ry'igiti amera. Ayo mashami mato twita arteriole. Aroroshye cyane kandi yoroshye. Ashobora kwiyongera cyane. Uko ni ko afasha mu kugenzura umuvuduko w'amaraso .

Imiyoboro y'inkari ihuza imitsi: Venules

Tuyita imitsi mito ikura amaraso mu mitsi ikayajyana mu mitsi . Iyi mitsi ikora nk'imiyoboro mito ihurira hamwe igakora uruzi runini.

Ni iki kibera imiyoboro y'amaraso?

Mu magambo make, inshingano nyamukuru y'imitsi y'amaraso ni ugutanga amaraso kuri buri rugingo n'ingingo zose z'umubiri wacu. Ibi biterwa nuko aya maraso arimo ogisijeni n'intungamubiri izi ngingo zikenera kugira ngo zikore. Nk'uko dukeneye ibyo kurya n'ibyo kunywa kugira ngo tubeho, ibi bintu ni ingenzi ku bice by'umubiri wacu. Nanone, indi nshingano ikomeye y'imitsi y'amaraso ni ukugarura imyanda na dioxyde de carbone ikorerwa muri izi ngingo no ku ngirangingo no kuyifasha kuyikura mu mubiri.

Iyi mitsi y'amaraso iherereye he?

Niba wibaza aho iyi mitsi y'amaraso iherereye mu mubiri wacu, igisubizo kiri hose! Guhera ku mitsi minini y'amaraso, irakura ikagera mu mashami mato, igakwirakwira mu mubiri wose nk'urushundura rw'igitagangurirwa. Uku ni ko buri rugingo n'uturemangingo two mu mubiri wacu bihabwa amaraso. Ese wari uzi ko hari miliyari z'iyi mitsi y'amaraso mu mubiri wacu! Inyinshi muri zo ni utwo dutsi duto twitwa ' Capillaries' , 'Venule', na 'Arterioles' twavuze mbere. Iyi mitsi mito ifitanye isano n'imitsi minini 160 gusa n'imitsi 200 gusa.

Umutsi w'amaraso w'ingenzi kandi munini mu mubiri wacu ni aorta, cyangwa icyo twita `(Aorta)`. Iyi ni yo nzira nyamukuru ikwirakwiza amaraso meza ava mu mutima ajya mu mubiri wose. Uyu mutsi w'amaraso unyura mu gituza, unyuze mu gifu, umanuka unyuze mu nda (igifu), maze ugacikamo amashami abiri ku kibuno (`Pelvis`), utanga amaraso mu mubiri wo hasi no ku maguru.

Mu buryo nk'ubwo, umutsi mukuru mu mubiri wacu ni vena cava, cyangwa `(Vena Cava)`. Ufite ibice bibiri. `Superior Vena Cava` iherereye mu ruhande rwo hejuru rw'iburyo rw'igituza. Izana amaraso yanduye ava mu mutwe, mu ijosi, mu maboko no mu gituza ajya mu mutima. `Inferior Vena Cava` iherereye hafi y'agahu , ku ruhande rw'iburyo. Izana amaraso ava mu maguru, mu birenge, mu nda no mu kibuno agaruka mu mutima.

Imitsi y'amaraso ikorwa ite? Ni ibihe bice byayo?

Ese wigeze ukuraho igitunguru? Gifite ibice, sibyo? Mu buryo nk'ubwo, imiyoboro yacu y'amaraso igizwe n'ibice bitatu by'ingenzi by'imitsi. Ibi bice bihurira hamwe kugira ngo bibe urukuta rw'imiyoboro y'amaraso. Reka turebe ibyo ari byo:

• Tunica intima : Uru ni rwo rugingo rw'imbere. Uko amaraso agenda, rukora kuri uru rugingo. Ruraryoshye cyane. Urabizi? Amaraso agomba gutembera neza, nta mbogamizi. Anagenga umuvuduko w'amaraso.Iyi "Tunica intima" inafasha mu gukumira kuvura amaraso no gukumira uburozi bwinjira mu maraso.

• Ibiganiro : Uru ni urwego rwo hagati. Rurimo imiyoboro irambura, ari yo miyoboro irambura, n'imitsi. Ibi bituma imiyoboro y'amaraso yaguka kandi ikanagabanuka. Indi nshingano y'ingenzi y'uru rwego ni ugufasha amaraso gukomeza gutembera mu cyerekezo kimwe. Rurambura kandi rugafatana nk'umukandara w'icyuma iyo bikenewe.

• Adventitia : Uru ni urwego rw'inyuma. Rurimo imitsi n'indi mitsi mito y'amaraso. Uru rwego niho imitsi y'amaraso yakira ogisijeni n'intungamubiri, kandi runafasha gukuraho imyanda. Mu by'ukuri, urwego rw'inyuma, rwitwa adventitia, rutanga imitsi y'amaraso imbaraga, imiterere, n'uburinzi.

Imitsi y'amaraso isa ite?

None se, iyi mitsi y'amaraso isa ite? Ubusanzwe iba imeze nk'"umuyoboro". Ariko, ntabwo ihora igenda mu murongo ugororotse, ahubwo igenda mu buryo bugoramye kandi buzunguruka mu mubiri wose. Imwe mu mitsi minini y'amaraso, cyane cyane imitsi, igaragara munsi y'uruhu rwacu. Ese wigeze utanga amaraso? Cyangwa warafashwe amaraso yawe kugira ngo apimwe? Ushobora kuba warabonye imitsi y'ubururu imbere mu kuboko kwawe, sibyo? Iyo ni imitsi. Ntabwo bitangaje kuba nubwo amaraso yacu atukura, asa n'ubururu munsi y'uruhu?

Ese imiyoboro y'amaraso nayo irwara indwara? Ni izihe?

Yego rwose. Kimwe n'ibindi bice byose by'umubiri wacu, imiyoboro y'amaraso ishobora kurwara indwara zitandukanye n'ibibazo. Reka turebe zimwe mu ndwara zikunze kugaragara:

• Aneurysm : Iki ni igihe urukuta rw'imitsi rucika intege cyangwa rukangirika, bigatuma rubyimba inyuma, rugakora ikibyimba gisa n'ikirahure. Ibi bishobora kubaho mu mitsi aho ari ho hose mu mubiri. Ikintu kibi cyane ni uko iyo aneurysm yacitse, ishobora gutera kuva amaraso menshi mu mubiri. Bishobora gushyira ubuzima mu kaga.

• Indwara z'imitsi : Iki cyiciro kirimo indwara nyinshi zikomeye. Urugero, harimo indwara y'imitsi y'umutima (CAD), indwara y'imitsi y'amaraso ya carotid (CAD), n'indwara y'imitsi yo mu gice cy'imbere (PAD). Izi ndwara zose zirimo kugabanuka buhoro buhoro kw'imitsi y'amaraso. Ibi akenshi biterwa n'indwara yitwa atherosclerosis.

• Ateriosclerosis : Muri make, iyi ni indwara aho ibinure, cholesterol, n'ibindi bintu byirundanya mu nkuta z'imitsi, nk'umwanda ufunga umuyoboro, bigatuma imitsi ifungana kandi igakomera. Ibi tubyita plaque zo mu mitsi.Ibi byongera ibyago byo kurwara indwara y'umutima cyangwa indwara yo gucika kw'imitsi .

• Amaraso apfundika : Hari igihe amaraso ashobora kupfundika mu mitsi cyangwa mu mitsi. Ayo mapfundika ashobora kubuza amaraso gutembera burundu cyangwa igice. Ibi bishobora gutera indwara zikomeye nko kugabanya imitsi mu mitsi (DVT), kugabanya imitsi mu bihaha, gucika imitsi, cyangwa kuziba imitsi burundu.

• Umuvuduko ukabije w'amaraso (`Umuvuduko ukabije w'amaraso / Umuvuduko ukabije w'amaraso`) : Benshi muri mwe mugomba kuba mwarumvise ibi. Iki ni cyo gihe umuvuduko uterwa n'amaraso ku nkuta z'imitsi urenze urugero rusanzwe. Iyo ibi bidagenzuwe igihe kirekire, bishobora kwangiza umutima, impyiko, amaso, ndetse n'ubwonko.

• Indwara ya Raynaud : Iyi ndwara ibaho iyo imitsi mito yo mu ruhu ifunze mu buryo butunguranye. Ibi bibaho cyane cyane iyo uhuye n'ubukonje cyangwa iyo ufite stress. Iminwe y'intoki ishobora guhinduka ibara ry'umukara, ubururu, no kubura ibinya.

• Imitsi y'imitsi ya Varicose : Iki nacyo ni ikintu abantu benshi babona. Cyane cyane mu maguru, imitsi isa n'aho igoramye, ibyimbye, ndetse rimwe na rimwe ipfutse. Ibi bishobora gutera ububabare no kumva amaguru aremereye.

• Ubusembwa bw'imitsi : Ibi ni ukwivanga kudasanzwe cyangwa kudahuza neza kw'imitsi. Urugero ni indwara yitwa ubumuga bw'imitsi itera amaraso. Ibi akenshi biba ari indwara ivukanwa .

• Vasculitis : Muri make, uku ni ukubyimba kw'imitsi y'amaraso. Ibi bishobora gutuma inkuta z'imitsi y'amaraso zikomera kandi zigafungana, ibyo bikaba byabuza amaraso gutembera neza.

Wamenya ute niba hari ikibazo? Ni ibihe bimenyetso?

Ibimenyetso by'indwara z'imitsi bishobora gutandukana cyane. Biterwa n'ubwoko bw'indwara n'ubukana bwayo. Hari igihe, nk'indwara zo mu mitsi twavuze, cyangwa ubumuga bw'imitsi, nta bimenyetso na bike bishobora kubaho kugeza igihe bibaye ikibazo gikomeye.

Ariko, muri rusange, niba ubonye kimwe muri ibi bimenyetso, ni byiza kujya kwa muganga kugira ngo akugire inama:
