Isibonakaliso esikhulu kunazo zonke sobungozi bokukhuluphala obuphuma emzimbeni womuntu sitholakala ku- isikhumba. Inani lamafutha esiswini liyasitshela uma ngabe kukhona ubungozi bezempilo kulokhu. Indlela elula futhi esheshayo yokuthola inani lamafutha esiswini umuntu anayo ngesilinganiso seteyipu. Siyisonga okhalweni, ezingeni lenkaba, futhi sinake ukuthi zingaki amasentimitha izinyathelo zokuzungeza.
Ukuthola umphumela onembile, kubalulekile ukuma ume mpo nokuthi isilinganiso seteyipu silingana. Ngaphezu kwalokho, i- isisu Akufanele kube nenkontileka, kepha ikhululeke ngokuphelele. Isibalo somkhawulo samadoda singu-100 cm, kanti kwabesifazane siphansi ngandlela thize, ama-95 cm.
Lapho isibalo siphezulu, kunengozi yokuthola izifo zemetabolic noma zenhliziyo, yize, ngenhlanhla, kuyinkinga enesisombululo naphezu kwendima ebalulekile edlalwa izakhi zofuzo. Ukhiye wokunqoba i- amafutha esiswini Imayelana nokuhlala usebenza. Kumele kuqashelwe ukuthi, phakathi kwabantu abakhuluphele ngokweqile, labo abanesimo sepheya (okhalweni namathanga abanzi) babhekwa njengabanempilo kunalabo abanesimo se-apula (okhalweni olubanzi).
Lapho umuntu ezuza isisindo esiningi kakhulu, umzimba wakhe uqala ukugcina amafutha ezindaweni ezingajwayelekile, njengezitho zomzimba. Amanye amafutha angaphansi kwesikhumba, kanti amanye ajulile, azungeze inhliziyo, amaphaphu, isibindi nezinye izitho. Amafutha ajulile abizwa kanjalo amafutha we-visceral, futhi kuvamile ngabantu abakhuluphele ngokweqile, yize futhi kungaba yinkinga ngisho nakubantu abancane.
