Amandla egazi kwiindonga zomthambo kuthiwa uxinzelelo lwegazi. Uxinzelelo oluqhelekileyo lubalulekile ekuhambeni okufanelekileyo kwegazi ukusuka entliziyweni ukuya kumalungu omzimba kunye nezicubu. Intliziyo nganye ibetha ngamandla igazi kuwo wonke umzimba. Kufuphi nentliziyo, uxinzelelo luphezulu, kwaye kude nalo lusezantsi.
Uxinzelelo lwegazi luxhomekeke kwizinto ezininzi, kubandakanya nokuba ingakanani igazi elimpompayoyo kunye nobubanzi bemithambo igazi elihamba kuyo. Ngokubanzi, okukhona igazi limpontshiwe kunye nokuncipha komthambo inyuka uxinzelelo. Uxinzelelo lwegazi lulinganiswa zombini njengezivumelwano zentliziyo, ezibizwa ngokuba yi-systole, kwaye njengoko iphola, ebizwa ngokuba yi-diastole. Uxinzelelo lwegazi lweSystolic lulinganiswa xa ikhontrakthi yentliziyo yesivumelwano. Uxinzelelo lwegazi lwe-diastolic lulinganiswa xa ii-ventricles zentliziyo zikhululekile.
Uxinzelelo lwe-systolic lwe-115 yeemilimitha zemekyuri luthathwa njengesiqhelo, njengoko kunjalo nangoxinzelelo lwe-diastolic engamashumi asixhenxe. Ukuba umntu unoxinzelelo lwegazi olungaguquguqukiyo lwe-140 ngaphezulu kwe-90, uya kuvavanywa uxinzelelo lwegazi oluphezulu.
Ukushiya kunganyangwa, uxinzelelo lwegazi oluphezulu lunokonakalisa amalungu abalulekileyo, anje ngengqondo kunye nezintso, kunye nokukhokelela kwistrowuku.
