Ushwankathelo

Intliziyo inamagumbi amane kunye nemithambo yegazi emine ephambili ethi izise igazi entliziyweni, okanye ihambise igazi.

Amagumbi amane yi-atrium elungileyo kunye ne-ventricle yasekunene kunye ne-atrium yasekhohlo kunye ne-ventricle yasekhohlo. Imithambo yegazi ibandakanya i-vena cava ephezulu nephantsi. Ezi zizisa igazi emzimbeni ukuya kwi-atrium elungileyo. Okulandelayo yimithambo yemiphunga ehambisa igazi lisuka kwi-ventricle yasekunene iye emiphungeni. I-aorta yeyona umthambo mkhulu womzimba. Ihambisa igazi eline-oksijini etyebileyo ukusuka kwi-ventricle yasekhohlo ukuya kuwo wonke umzimba.

Ngaphantsi kwengubo eqinileyo yentsimbi yentliziyo, uyayibona ibetha.

Ngaphakathi kwamagumbi kukho uthotho lwezivalo zendlela enye. Ezi zigcina igazi lihamba kwicala elinye.

Idayi ifakwe kwi-vena cava ephezulu, iya kudlula kuwo onke amagumbi entliziyo ngexesha lomjikelo wentliziyo.


Igazi kuqala lingena kwi-atrium elungileyo yentliziyo. Ukuncipha kwemisipha kunyanzela igazi nge-tricuspid valve ukuya kwi-ventricle elungileyo.

Xa izivumelwano ezifanelekileyo ze-ventricle, igazi linyanzeliswa nge-pulmonary semilunar valve kwi-pulmonary artery. Emva koko iya kwimiphunga.

Emiphungeni, igazi lifumana ioksijini emva koko igqibe ngemithambo yemiphunga. Ibuyela entliziyweni kwaye ingena kwi-atrium yasekhohlo.

Ukusuka apho, igazi linyanzeliswa nge-mitral valve ukuya kwi-ventricle yasekhohlo. Le yimpompo yemisipha ethumela igazi kuwo wonke umzimba.

Xa iikhontraki ze-ventricle yasekhohlo, inyanzela igazi kwi-aortic semilunar valve nakwi-aorta.

I-aorta kunye namasebe ayo athatha igazi alise kuzo zonke izicwili zomzimba.
