Ziziphi iintlobo zegazi ezikhoyo kwaye kungani zichazwe?
Uhlalutyo olubanzi lwegazi, oluqhutywe ngexesha lokukhulelwa, likuvumela ukuba uhlole imeko yomzimba wesifazane, ukubonakalisa iinkqubo ezivuthayo ezivuthayo. Ukufunda ngokuthe ngqo kubonisa ukuphendulwa komzimba womntu kwiinguqu ezenzeka kuyo, kubandakanywa nezifo. Ukuqwalaselwa ngokugqithisileyo ekuhlalutyweni kweziphumo kunikezelwa kwisibonakaliso esinjengezinga le-hemoglobin, ukwehla kwayo kungabonakalisa i- anemia , eqinisweni, ebangela i-hypoxia yomntwana.
Ukuze kuqinisekiswe ukukhulelwa ngokwawo ngendlela yokuhlolwa kwegazi, ngomhla we-5 uphando lwenziwe, olubizwa ngokuba ngumlinganiselo we-hCG. Ukubalwa kwebala kuvela kumhla wokubanjwa kwecala. Ngokukhawuleza, le hormone iqalisa ukuhlanganiswa emva kokukhulelwa kwaye ibonise ukufakwa.
Uhlalutyo lwe-Genetic yegazi, olumiselweyo ngexesha lokukhulelwa, lusetyenziswe ukubonisa kwiindawo zokuqala zokukhula kwabantwana bokungabikho kokuzalwa okungqinelana nokuguqulwa kwamagciwane. Phakathi kwezi ziyi-syndrome ye-Edwards, i-Down, ukuphulwa, njenge-trisomy, i-polysomy. Xa zisungulwe, umba wokukhupha isisu usombulule.
Uvavanyo lwegazi lwegazi, olumiselwe kwabasetyhini ngethuba lokubambana, linikeza ithuba lokuvavanya iimpawu zeprotheni, i-lipid metabolism, ukuxutywa kwamatyu egazini, inqanaba lamavithamini kunye nezixhobo ezincedisayo. Ingqwalasela ekhethekileyo ihlawulwa kwiiprotheni zengxube, iimitha ze-nitrogen metabolism. Uvavanyo lwe-biochemical luquka ukuhlolwa kwegazi kwi-glucose, edlalwa rhoqo ngexesha lokukhulelwa. Nguye ovumela ukuba abone ukuphulwa okunjalo njengesifo sikashukela. Ngenxa yobuthathaka obuncitshiweyo bomzimba wesetyhini okhulelwe ukuba u-insulin obangelwa yintsebenzo yeprolactin kunye ne-estrogens, utshintsho lwe-glucose ukunyamezela, olukhokelela ekuphuhlisweni kwesifo sikashukela sesifo sikashukela.
