Amandla egazi ezindongeni zemithambo abizwa ngokuthi umfutho wegazi. Ingcindezi ejwayelekile ibalulekile ekugelezeni okufanele kwegazi lisuka enhliziyweni liye ezithweni zomzimba nezicubu zomzimba. Inhliziyo ngayinye ishaya ngamandla igazi kuwo wonke umzimba. Eduze kwenhliziyo, ingcindezi iphakeme, futhi kude nayo yehla.
Umfutho wegazi uncike ezintweni eziningi, kufaka phakathi ukuthi inhliziyo ishaya igazi elingakanani nobubanzi bemithambo igazi elihamba ngayo. Ngokuvamile, lapho igazi elimpontshwa ngokwengeziwe futhi umthambo uncipha kuba namandla ingcindezi iba phezulu. Umfutho wegazi ulinganiswa ngazo zombili njengezinkontileka zenhliziyo, ezibizwa nge-systole, futhi njengoba iphumula, ebizwa nge-diastole. Umfutho wegazi we-Systolic ulinganiswa lapho inkontileka yama-ventricles enhliziyo. Umfutho wegazi we-diastolic ulinganiswa lapho ama-ventricles enhliziyo ekhululekile.
Ukucindezelwa kwe-systolic okungamamilimitha ayi-115 e-mercury kubhekwa njengokujwayelekile, kanjalo nengcindezi ye-diastolic ka-70. Imvamisa, le ngcindezi kungashiwo ukuthi ingu-115 ngaphezulu kwama-70. Uma umuntu ene-blood pressure engaguquguquki efunda okungu-140 ngaphezu kwama-90, uzohlolwa umfutho wegazi ophakeme.
Uma ingalashwa, umfutho wegazi ophakeme ungalimaza izitho ezibalulekile, njengobuchopho nezinso, futhi kuholele ekushayweni unhlangothi.
