Imibhobho yokuhamba kwegazi

Livela
Imibhobho yegazi.

Umbhobho wegazi yityhubhu engumthambo ethwala igazi xa lihamba lijikeleza umzimba. Imithambo yegazi ethatha igazi entliziyweni ingoonothumela. Ize imithambo yegazi ebuyisela igazi entliziyweni ibengoonobuyisa. Imithambo ezii-Capillaries yona iphakathi koonobuyisa noonothumela kwaye ezi-capillaries zondla igazi nge-tissue. 

Intliziyo xa idibene nayo yonke imithambo esemzimbeni ibizwa ngokuba yi-circulatory system. igazi lihamba ngokumpompa kwentliziyo lize lithwale ioksijini liyise kwii- tissues.

Isenzo sokuya ivuleka imithambo yegazi sibizwa ngokuba yi-vasodilation, oku kwenzeka kunceda ukuba umzimba ukwazi ukugxotha amandla obushushu  (igama elingu-vas- ngesiLatini lithetha ukuthi  "isitya sokukhongozela" okanye "isikhongozeli"[1]). Ukwakheka kwemithambo yegazi kubizwa ngokuba yi-vasoconstriction, inqanda ukuba umzimba ungaphulukani nobushushu.
