Ni gute amaraso agenda mu mubiri wawe wose? (Urugendo rw'amaraso n'imitsi itembera mu maraso) Reka tubigenzure mu buryo bworoshye!

Ese wigeze wibaza uburyo iki kintu cyitwa amaraso kizenguruka imibiri yacu nta kibazo? Ntabwo ari ibintu bitangaje? Buri segonda umutima wacu utera, aka gasanduku gato kanyuza amaraso mu buryo bw'imiyoboro mu mibiri yacu yose. Ibi ni byo twita ' Sisitemu yo Gutembera kw'amaraso ' . Iyi miyoboro imeze nk'imiyoboro yoroshye itwara amaraso ku gice cyose cy'umubiri. None se, reka tubiganireho mu buryo burambuye?

Kuki amaraso ari ay'agaciro gakomeye kuri twe?

Amaraso ni ingenzi cyane mu buzima bwacu. Tekereza gato, ni yo afasha buri karemangingo gato n'ingingo mu mubiri wacu kubaho no gukora. Dore ibintu by'ingenzi bibaho ku maraso:

• Amaraso ajyana ogisijeni n'intungamubiri by'ingenzi mu mubiri wacu, kimwe no kuzana ibiryo n'ibinyobwa mu ngo zacu.
• Amaraso kandi afasha gukuramo dioxyde de carbone idakenewe n'indi myanda yiyongera mu ngingo ikayikura mu mubiri, kimwe no gusohora imyanda mu rugo rwawe.
• Kubera ibi byose rero, amaraso ni ingenzi mu kubungabunga ubuzima bwacu no gutuma buri gice cy'umubiri wacu kigira ubuzima bwiza .

Ese usobanukiwe ukuntu amaraso ari ay'agaciro?

Hari ubwoko butatu bw'ingenzi bw'imitsi y'amaraso!

Hari ubwoko butatu bw'ingenzi bw'imitsi ijyana amaraso mu mubiri wacu. Nk'uko imihanda ifite imihanda minini, imihanda mito, n'imihanda yo ku nkengero.

1. Imitsi y'amaraso - imiyoboro itwara amaraso meza iva mu mutima

Imitsi ni imitsi itwara amaraso akungahaye kuri ogisijeni (ubusanzwe igaragara mu ibara ritukura ku mashusho) n'intungamubiri ziva mu mutima wacu zijya mu zindi ngingo zose z'umubiri. Tekereza nk'aho umutima ari ipompo y'amazi, naho imitsi ikaba nk'imiyoboro minini itwara amazi meza ava muri iyo pompe ijya mu busitani bwose.

• Iyi gahunda y'imitsi itangirana na aorta, umuyoboro munini w'amaraso usohoka mu mutima. Ni nk'umuyoboro munini usohoka mu kigega cy'amazi kinini.
• Ibi bitwara amaraso akungahaye kuri ogisijeni ava mu mutima ajya mu ngingo zose z'umubiri.
• Uko ugenda uva mu mutima, iyi mitsi igenda yigabanyamo amashami, buhoro buhoro igenda iba mito. Nk'uko uruzi runini rwigabanyamo imigezi mito.

Rero, akazi gakomeye k'imitsi ni ugukwirakwiza amaraso meza mu mubiri wose .

2. Capillaries – ahantu hato cyane ho guhanahana amakuru

Imiyoboro ya capillaries ni urusobe rw'imiyoboro y'amaraso mito cyane kandi myiza cyane. Iyi ni yo ihuza imiyoboro ibiri minini y'amaraso, imiyoboro y'amaraso n'imitsi. Tekereza ko ari urukurikirane rw'imihanda mito iri hagati y'imihanda ibiri minini.

• Inkuta z'izi capillaries ni nto cyane, zimeze nk'urushundura.
• Utu dukuta duto dutuma ibintu byiza nka ogisijeni n'intungamubiri biva mu maraso bijya mu turemangingo tw'imitsi, n'ibintu bidakenewe nka dioxyde de carbone n'imyanda ikorerwa mu turemangingo tw'imitsi bigaruka mu maraso . Ni nko gucuruza ibicuruzwa ku isoko.

Mu by’ukuri, iyi gahunda y’ingenzi ku rwego rw’uturemangingo tw’umubiri ibera muri utwo turemangingo duto. Mu by’ukuri, ni duto cyane ku buryo hari uturemangingo duto duto kurusha umusatsi wacu! Ariko akazi bakora ni kanini cyane, si byo se?

3. Imitsi – imitsi ijyana amaraso mabi mu mutima

Imitsi ni imitsi itwara amaraso yangiritse cyangwa "yanduye" (akunze kugaragara mu ibara ry'ubururu ku mashusho) ayivana mu ngingo z'umubiri wacu ayijyana mu mutima. Ni nk'imiyoboro ikusanya amazi yakoreshejwe ikayasubiza mu kigega.

• IbiImitsi y'amaraso itwara amaraso afite ogisijeni nkeya n'umwuka wa karuboni mwinshi mu mubiri ikawujyana mu mutima.
• Uko iyo mitsi yegera umutima, irafatanya ikongera ikaba minini. Nk’uko imigezi mito ihurira hamwe igakora uruzi runini.
• Amaherezo, umutsi munini witwa `superior vena cava` uzana amaraso ava mu mutwe no mu maboko ukayajyana mu mutima. Mu buryo nk'ubwo, umutsi munini witwa `inferior vena cava` uzana amaraso ava mu nda no mu maguru ukayajyana mu mutima.

Bityo rero, inshingano nyamukuru y'imitsi ni ukugarura amaraso arimo imyanda ikora mu mubiri mu mutima no kuwuyobora kugira ngo utunganywe .

Ubu buryo bw'imitsi y'amaraso bungana iki kurusha uko ubitekereza?

Noneho urabona uburyo imitsi, imitsi, n'imitsi igoranye mu mibiri yacu. Ese wari uzi ko imitsi yose y'amaraso - ni ukuvuga imitsi yose, imitsi, n'imitsi ivanze hamwe - ifite uburebure bwa kilometero zirenga 60.000 ! Amaraso yacu atembera muri iyi sisteme nini buri gihe. Ni nk'urusobe rw'imihanda mu mujyi, imodoka zigenda zigaruka buri gihe. Rero umutima wacu ni wo ufasha mu kuvoma aya maraso yose. Ni wo muyobozi w'iyi gahunda yose.
