Reka dusobanukirwe neza uburyo amaraso atembera mu mubiri wacu? (Sisitemu yo kuzenguruka amaraso)

Muraho! Mumeze mute? Uyu munsi tugiye kuvuga ku buryo butangaje kandi bw'ingenzi mu mubiri wacu. Ubwo ni bwo buryo bwacu bwo kuzenguruka kw'amaraso, cyangwa nk'uko bamwe babyita, "Sisitemu yo Kuzenguruka Inzira z'Imitsi". Hari igihe ushobora kuba warigeze kumva ko yitwa "Sisitemu y'Imitsi y'Imutima". Ayo yombi ni amazina y'uburyo bumwe. Reka turebe icyo ari cyo, uko bikora, n'uko byakomeza kubaho neza.

Urusobe rw'amaraso ni iki? Mu magambo make...

Muri make, inzira z'amaraso mu mubiri wawe zigizwe n'umutima n'imitsi y'amaraso . Ibi byombi bikoresha amaraso mu gutwara intungamubiri kuri buri turemangingo two mu mubiri wacu no gukura imyanda muri utwo turemangingo.

Tekereza umutima wawe nk'ipompo y'amazi. Iyi pompe ipompa amaraso mu rusobe rw'imitsi y'amaraso mu mubiri wawe wose. Iyi mitsi y'amaraso yitwa imitsi n'imitsi . Aya maraso atwara ogisijeni - umwuka utanga ubuzima duhumeka - n'intungamubiri ku mitsi yawe, mu ngingo zawe, no mu ngingo zawe. Ni na bwo buryo bukusanya imyanda ikayijyana mu ngingo aho ishobora gukurwa.

Ni izihe nshingano z'ingenzi z'iyi gahunda?

Sisitemu yacu y'amaraso ikora imirimo itatu y'ingenzi:

1. Gutwara amaraso mu mubiri wose.

2. Gutwara ogisijeni n'intungamubiri mu ngingo zacu, mu mitsi no mu ngingo.

3. Diyozede ya karuboni – umwuka utagifite akamaro mu mibiri yacu kandi uvamo iyo duhumeka – ni ugukura imyanda n'imyanda ya shimi mu ngingo zacu.

Amanywa n'ijoro, ndetse no mu gihe usinziriye, umutima wawe uhora utera amaraso mu mubiri wawe wose, nk'aho ugenda mu ruziga. Iyo dukurikije iyi nzira y'amaraso, atangirira mu mutima akanyura mu mitsi minini y'amaraso yitwa "Imitsi" kugira ngo ikwirakwize amaraso mu ngingo zacu no mu ngingo zacu.

Mu ngingo zacu, mu rusobe rw'imitsi y'amaraso myiza cyane yitwa capillaries , umwuka wa ogisijeni mu maraso urarekurwa maze imyanda igasubizwa mu maraso. Nyuma yo kuva muri izi ngingo n'ingingo, aya maraso asubira mu mutima binyuze mu mitsi y'amaraso yitwa imitsi. Aya maraso anyura mu mutima ajya mu bihaha, aho yongera gushyirwamo ogisijeni, maze urugendo rugatangira. Ibi bibaho incuro ibihumbi ku munsi, buri segonda umutima wawe utera.

Ese ushobora kwiyumvisha, umutima wawe upompa litiro zigera ku 2.000 z'amaraso mu mubiri wawe buri munsi! Mu bihe nk'ibi, iyo ukora imyitozo ngororamubiri, umutima wawe upompa amaraso menshi kurushaho. Ibi bivuze ko inzira zacu zo gutemberamo amaraso zihuza n'ingano y'amaraso n'umwuka umubiri wacu ukeneye.

Imwe mu nshingano z'ingenzi z'urusobe rw'amaraso ni ugukomeza gutanga amaraso mu bwonko no mu mutima.Kubera ko, iyo ubwonko butakiriye amaraso akenewe, bushobora guta ubwenge mu masegonda make. Iyo amaraso ahagaze mu minota ine, ubwonko bushobora kwangirika. Mu buryo nk'ubwo, iyo umutima utakiriye amaraso ahagije, imikorere yawo yo gupompa izahita inanirwa.

None se, aya maraso yinjira ate mu mubiri wose?

Sisitemu yacu y'amaraso, cyangwa "Sisitemu y'umutima n'imitsi" (Cardiovascular System), ikora hifashishijwe imiyoboro y'amaraso. Imiyoboro imwe n'imwe y'amaraso ("Imitsi") igarura amaraso mu mutima, mu gihe indi miyoboro y'amaraso ("Imitsi") ikura amaraso mu mutima.

Imitsi yawe y'amaraso, hamwe n'umutima n'ibihaha, bikomeza gupompa amaraso mu mubiri wawe wose. Dore uko bikora:

1. Amaraso adahumeka neza aturuka mu mutima ajya mu bihaha. Aya maraso anyura mu gice cy'imitsi y'ibihaha (imitsi migari y'ibihaha).

2. Ogisijeni yongerwa muri aya maraso ari mu bihaha byawe.

3. Imitsi y'ibihaha itwara aya maraso akungahaye kuri ogisijeni mu bihaha ikayajyana mu gice cy'ibumoso cy'umutima.

4. Kuva mu gice cy'ibumoso cy'umutima, aya maraso akungahaye kuri ogisijeni yoherezwa mu gice cy'ibumoso cy'umutima. Iki gice cy'imitsi y'umutima gitanga amaraso mu gice cyose cy'umubiri binyuze mu mitsi.

5. Uko amaraso agenda mu mubiri wose no mu ngingo, atanga intungamubiri, agakwirakwiza imisemburo, kandi agakusanya imyanda.

6. Hanyuma, imitsi igarura amaraso adafite ogisijeni, akungahaye kuri dioxyde de carbone mu mutima. Amaraso ava mu mutima yoherezwa mu bihaha.

7. Mu bihaha, umwuka wa dioxyde de carbone urasohoka, ogisijeni yongerwa mu maraso mu buryo bwo guhinduranya. Hanyuma, iyo usohoye umwuka, uwo mwuka wa dioxyde de carbone urasohoka.

Uburyo amaraso akura umwuka wa ogisijeni mu bihaha agasubira mu mutima bwitwa uburyo bwo kuzenguruka kw'ibihaha . Uburyo bwo gutanga amaraso afite ogisijeni mu mubiri wose bwitwa uburyo bwo kuzenguruka kw'umubiri .

Iyi sisitemu iherereye he?

Umutima wawe uherereye hagati mu gituza cyawe. Uhujwe n'imitsi itwara amaraso mu mubiri wawe wose.

Ni ibihe bice by'urusobe rw'amaraso mu mubiri?

Umutima wawe n'imitsi y'amaraso ni byo bigize urusobe rw'amaraso. Buri gice muri ibi gifite akazi kihariye ko gufasha kwimura amaraso mu mubiri wawe wose. Uku ni ko uturemangingo twacu tubona ogisijeni n'intungamubiri ndetse n'uburyo imyanda ikurwaho.

Ni ibihe bice bine by'ingenzi by'urusobe rw'amaraso mu mubiri?

Ibice by'ingenzi by'urusobe rw'amaraso ni ibi bikurikira:

• Umutima: Uru ni urugingo rugizwe n'imitsi. Rupompa amaraso mu mubiri wose. Umutima ni wo rugingo rwonyine mu miyoboro y'amaraso. Ibihaha byawe ni iby'urusobe rw'ubuhumekero.
• Imitsi: Iyi ni imiyoboro mito kandi y'imitsi itwara amaraso afite ogisijeni mu mutima ikayajyana mu bice byose by'umubiri. Umutsi munini mu mubiri wacu niAorta. Imitsi y'umutima iva kuri aorta, hanyuma uko igenda iva ku mutima, iva muri iyo mitsi mito (arteriole).
• Imitsi: Iyi mitsi ijyana amaraso yakuwemo umwuka mu mutima. Imitsi itangira ari mito (venules) hanyuma ikagenda iba minini uko yegera umutima. Imitsi ibiri y'ingenzi (vena cava iruta izindi na vena cava iciriritse) ijyana amaraso mu mutima. Imitsi yo mu maguru yawe ifite imitsi ibuza amaraso gutembera inyuma.
• Imitsi y'amaraso: Iyi mitsi ihuza imitsi mito cyane (arteriole) n'imitsi y'amaraso (venule). Inkuta z'imitsi y'amaraso ni nto cyane, bigatuma ogisijeni, dioxyde de carbone, intungamubiri, n'imyanda biva mu maraso bijya mu turemangingo, no mu turemangingo bijya mu maraso.

Imiyoboro y'amaraso isa ite? Ingana iki?

Ushobora gutekereza ko umutima ari wo uyobora amaraso mu mubiri. Uhujwe n'urusobe rw'imitsi y'amaraso ikwirakwira mu mubiri wose.

Niba wigeze ubona imiyoboro y'amazi cyangwa imiyoboro y'amazi mabi munsi y'umuhanda, uzi ko ari minini cyane. Iyi miyoboro igabanamo imito izana amazi mu ngo ikajyana imyanda. Mu buryo nk'ubwo, imiyoboro y'amaraso ijyana amaraso mu mutima imeze nk'imiyoboro minini iri munsi y'umuhanda. Ni yo miyoboro minini y'amaraso mu mubiri. Uko ugenda uva mu mutima, iyi miyoboro igabanamo imiyoboro mito y'amaraso ifasha gukwirakwiza ogisijeni mu mubiri wose no gukuraho imyanda.

Imitsi y'amaraso igizwe n'ibice by'ingirabuzimafatizo, imitsi, n'imitsi irabagirana. Imitsi yo mu mitsi yawe igenzura ubugari bwayo. Ibi bigira ingaruka no ku muvuduko w'amaraso yawe. Iyo imitsi y'amaraso yagutse, ibi byitwa "Vasodilation," kandi umuvuduko w'amaraso uragabanuka. Iyo imitsi y'amaraso yagabanutse, ibi byitwa "Vasoconstriction," kandi umuvuduko w'amaraso uriyongera.

Umutima wawe ugizwe n'imitsi n'izindi ngingo. Amaraso atemba mu byumba bine.

Umutima wawe ubusanzwe ungana n'inkovu yawe. Ariko niba ufite indwara y'umutima, ushobora kuba munini cyane. Imitsi yawe y'amaraso izenguruka umubiri wawe wose, kuva hejuru kugeza hasi. Rero iyi miyoboro ni minini nkuko nawe uri muremure kandi mugari. Mu by'ukuri, hari imitsi y'amaraso irenga ibirometero 60.000 mu mibiri yacu!

Umutima usanzwe upima hagati ya ounces 8 na 12, ariko ibi bishobora gutandukana bitewe n'igitsina, ibiro by'umubiri muri rusange, n'indwara.

Ni izihe ndwara n'ibibazo bikunze kugira ingaruka ku mikorere y'amaraso mu mubiri?

Ibibazo byinshi bigira ingaruka ku bice by'imiyoboro y'amaraso biterwa no gutembera buhoro cyangwa kuziba kw'amaraso mu miyoboro y'amaraso. Kubera ko imiyoboro yacu y'amaraso itanga ogisijeni ku mubiri wose, iyo hari imiyoboro y'amaraso yazibye, biragoye gutanga ogisijeni.

Dore bimwe mu bibazo bikunze kugira ingaruka ku mikorere y'amaraso:

• Umuvuduko ukabije w'amaraso
• Kolesteroli nyinshi
• Arrhythmia (umutima utari usanzwe utera)
• Indwara y'umutima
• Ihindagurika ry'imitsi y'umutima
• Umutima unaniwe ('Umutima unaniwe' - intege nke mu mitsi y'umutima wawe)
• Aneurysm ikunze kugaragara cyane mu muyoboro w'amaraso cyangwa mu bwonko.
• Igisebe cy'imitsi
• Atherosclerosis - plaque yiyongera mu mitsi yawe
• Indwara z'umutima
• Indwara z'imitsi ( urugero, thrombosis y'imitsi yo mu bwonko igana kure ndetse no kugabanuka k'imitsi yo mu bihaha)

Guhindura imibereho yawe byoroheje n'inama zo kugumisha urusobe rw'amaraso mu buzima bwiza

Hari ibintu byinshi ushobora gukora kugira ngo umutima wawe n'imitsi y'amaraso bikomeze kugira ubuzima bwiza. Dore bimwe muri byo:

• Kora imyitozo ngororamubiri buri gihe. Ishyirireho nibura iminota 150 mu cyumweru.
• Gusinzira ukeneye buri joro.
• Kugenzura umuvuduko ukabije w'amaraso.
• Kugenzura urugero rw'ibinure byinshi bya cholesterol.
• Kwirinda ibikomoka ku itabi.
• Kurya indyo yuzuye umutima. Urugero, indyo irimo fibre nyinshi n'ibinure bike byuzuye.
• Kugukomeza kugira ibiro byiza.
• Kugumana urugero rw'isukari mu maraso rusanzwe.
• Shaka uburyo bwiza bwo kugabanya stress.

Ese inkuru y'amaraso atukura n'ubururu ni ukuri? Ese imitsi ihora itwara amaraso arimo ogisijeni?

Hari abantu bibwira ko amaraso y'ubururu atemba mu mitsi mu bice bimwe na bimwe by'umubiri wacu. Ariko mu by'ukuri, buri gitonyanga cy'amaraso yacu ni umutuku. Amaraso akura ibara ryayo ritukura muri poroteyine ikungahaye kuri feri yitwa hemoglobine . Ibi biboneka mu turemangingo dutukura tw'amaraso. Hari abantu bise amaraso akungahaye kuri ogisijeni "amaraso atukura."

Imitsi yawe itwara amaraso afite umwuka muke wa ogisijeni. Ibi rimwe na rimwe byitwa "amaraso y'ubururu" kuko imitsi yawe ishobora kugaragara nk'ubururu munsi y'uruhu rwawe. Ariko mu by'ukuri amaraso ni umutuku. Imitsi ni ubururu bwijimye bitewe n'urugero ruto rwa ogisijeni.

Imitsi itwara amaraso menshi arimo ogisijeni. Ariko hari ibitandukanye bibiri: umutsi w'ibihaha n'umutsi w'ibihaha. Umutsi w'ibihaha utwara amaraso adahumeka mu bihaha. Umutsi w'ibihaha utwara amaraso afite ogisijeni mu mutima.

Amaherezo, icyo ugomba kwibuka! (Ubutumwa bwo kujyana mu rugo)

Imikorere y'amaraso mu mubiri wawe ni urwego rutangaje rukora akazi k'ingenzi ko kugukomeza kubaho, ruguha umwuka mwiza n'intungamubiri buri gihe. Ufite imbaraga zo gukomeza umutima wawe n'imitsi y'amaraso.Kureka kunywa itabi, kurya indyo yuzuye, gukora imyitozo ngororamubiri, no kugenzura umuvuduko w'amaraso na cholesterol byose ni byiza ku mikorere y'amaraso yawe. Baza muganga wawe icyo wakora kugira ngo urinde kandi ukomeze umutima wawe n'imiyoboro y'amaraso. Komeza ugire ubuzima bwiza!
