Yaye eneneni, kuzo zombini ezi meko, le imizimba kwakheka ngenxa yeenguqu kunye utshintshwano leeseli umongo wethambo. Hormone ziveliswa thymus abadala kunye nabantwana, ajike iiseli stem ibe thymocytes. Nabo ke, kweyela kwiindawo nkovu okanye udakada. Ngenxa yoko, thymocytes nibe baguqulwe T-lymphocyte. I-B-lymphocyte senziwa similise iiseli esiqwini, ngokutsho iingcali ezininzi, kukuba ngqo kwi umongo wethambo.

Ngaphandle kwento yokuba thymus libandakanyeka inguqu iiseli lomongo wethambo kule ndlala rhoqo wavelisa thymopoietin kunye thymosin, ezo iincindi zamadlala kudlala indima enkulu immune komzimba.

Kukho Kukwaphula emininzi imisebenzi yalo iziko. Kukho abantwana ubani akananto thymus. Iimpawu ezibonisa ukungabikho ebesakugunyaziswa nguMthetho weGunya, akukho nto kodwa ukuhla kweelana umzimba womntu kwezinye izifo ezosulelayo. Oku kwakhona ziquka nezinye iinkalo.

Abo yesakhono ukugqiba ukwanda thymus usana ezinye iimpawu. Umzekelo, kwimeko enjalo aphela rhoqo wabona ekweneni tonsils, adenoids, iindawo nkovu idumbile. Uyakwazi ukwenza i X-reyi yesifuba, nto leyo eya ngoko nangoko uphawula ukwanda thymus.

izifo yokusetyenziswa wachaza Authority namhlanje iphathwa ngempumelelo. Ngamanye amaxesha ukususwa thymus efunekayo. Nangona kunjalo, ngaphandle koku, ugqirha ukubekwa ucwangciso olukhethekileyo. Xa kunjalo, umntu ukugula kakhulu zigqunyiwe, ukwenzela ukunciphisa ingozi yosulelo. Ukuba uphawula ukuba wagula kakhulu, kunye nezifo (esosulelayo) ithatha ixesha elide, qhagamshelana nogqirha wakho. Iya kulimisela uphando uze ukhethe indlela efanelekileyo yonyango.
