Ukubuka konke

Inhliziyo inamagumbi amane nemithambo yegazi eyinhloko emine eletha igazi enhliziyweni, noma ehambisa igazi.

Amakamelo amane yi-atrium efanele kanye ne-ventricle yangakwesokudla ne-atrium yesobunxele ne-ventricle engakwesokunxele. Imithambo yegazi ifaka i-vena cava ephakeme futhi engaphansi. Lokhu kuletha igazi emzimbeni ku-atrium efanele. Okulandelayo ngumthambo we-pulmonary ohambisa igazi kusuka ku-ventricle efanele uye emaphashini. I-aorta ingumthambo omkhulu womzimba. Ithwala igazi elinomoya-mpilo lisuka emgudwini ongakwesobunxele liye kuwo wonke umzimba.

Ngaphansi kokumboza okunzima okunamicu kwenhliziyo, uyayibona ishaya.

Ngaphakathi kwamagumbi kunochungechunge lwama-valve wendlela eyodwa. Lokhu kugcina igazi ligobhoza liqonde ohlangothini olulodwa.

Idayi ejojelwe kwi-vena cava ephakeme, izodlula kuwo wonke amagumbi enhliziyo ngesikhathi somjikelezo wenhliziyo owodwa.

Igazi kuqala lingena e-atrium elungile yenhliziyo. Ukuncipha kwemisipha kuphoqa igazi ngokusebenzisa i-tricuspid valve iye ku-ventricle efanele.

Lapho izinkontileka ze-ventricle efanele, igazi liphoqelelwa nge-valve semilunar ye-pulmonary emthanjeni we-pulmonary. Bese iya emaphashini.

Emaphashini, igazi lithola umoya-mpilo bese lihamba ngemithambo yamaphaphu. Ibuyela enhliziyweni bese ingena e-atrium yangakwesobunxele.

Ukusuka lapho, igazi liphoqelelwa nge-mitral valve lingene ku-ventricle engakwesokunxele. Leli yimpompo yemisipha ethumela igazi kuwo wonke umzimba.

Lapho inkontileka ye-ventricle yangakwesobunxele, iphoqa igazi nge-aortic semilunar valve futhi lingene ku-aorta.

I-aorta namagatsha ayo ahambisa igazi kuzo zonke izicubu zomzimba.
