Igazi lijikeleza kuwo wonke umzimba, lihlinzeka ngemisoco yonke indawo futhi lisusa ukungcola, ngakho-ke kufanele ligcinwe ngaphansi kwezimo ezijwayelekile.Kodwa-ke, lapho umkhumbi wegazi ulimala futhi uqhuma, umzimba uzokhiqiza uchungechunge lokusabela, okuhlanganisa i-vasoconstriction ukunciphisa ukulahlekelwa kwegazi, ukuhlanganiswa kwe-platelet ukuze kuvinjwe isilonda ukuze kumiswe ukopha, kanye nokusebenza kwezici zokuxhuma ukuze zakhe i-thrombus ezinzile ukuze uvimbele. ukuphuma kwegazi kanye Inhloso yokulungisa imithambo yegazi yindlela yomzimba yokuphuma kwegazi.

Ngakho-ke, umphumela we-hemostatic womzimba ungahlukaniswa ube izingxenye ezintathu.Ingxenye yokuqala ikhiqizwa ukuxhumana phakathi kwemithambo yegazi nama-platelet, okubizwa ngokuthi i-primary hemostasis;ingxenye yesibili ukusebenza kwezici coagulation, futhi ukwakheka reticulated coagulation fibrin, okuyinto esonga platelets futhi abe thrombus ezinzile, okuthiwa i-hemostasis yesibili, okuyilokho esikubiza ngokuthi coagulation;Kodwa-ke, lapho igazi liyeka futhi lingaphumi, enye inkinga ivela emzimbeni, okungukuthi, imithambo yegazi ivinjiwe, okuzothinta ukunikezwa kwegazi, ngakho-ke ingxenye yesithathu ye-hemostasis ngumphumela wokuqedwa kwe-thrombus ukuthi. lapho umkhumbi wegazi ufinyelela umphumela we-hemostasis nokulungiswa, i-thrombus izohlakazwa ukuze kubuyiselwe ukuhamba kahle komkhumbi wegazi.

Kuyabonakala ukuthi i-coagulation empeleni iyingxenye ye-hemostasis.I-hemostasis yomzimba iyinkimbinkimbi kakhulu.Ingasebenza lapho umzimba uyidinga, futhi lapho ukuhlangana kwegazi kuyifezile injongo yayo, ingahlakaza i-thrombus ngesikhathi esifanele futhi ilulame.Imithambo yegazi ivaliwe ukuze umzimba ukwazi ukusebenza ngendlela evamile, okuyinhloso ebalulekile ye-hemostasis.

Izifo ezivame kakhulu zokopha ziwela ezigabeni ezimbili ezilandelayo:

.

1. Ukungajwayelekile kwemithambo neplatelet

Isibonelo: i-vasculitis noma ama-platelet aphansi, iziguli zivame ukuba namachashazi amancane okopha emaphethelweni aphansi, okuyi-purpura.

.

2. Isici se-coagulation esingavamile

Kubandakanya i-congenital hemophilia kanye nesifo sika-Wein-Weber noma isifo sokusha kwesibindi, ubuthi begundane, njll., kuvame ukuba namachashaza amakhulu e-ecchymosis emzimbeni, noma ukopha okujulile kwemisipha.

Ngakho-ke, uma unokopha okungenhla okungavamile, kufanele uthintane ne-hematologist ngokushesha ngangokunokwenzeka.
