Ukubuka konke

Amangqamuzana egazi akhethekile amhlophe abizwa ngama-lymphocyte adlala indima enkulu ekuphenduleni kwamasosha omzimba kubahlaseli bangaphandle. Kunamaqembu amabili amakhulu, womabili akha umongo wethambo.

Iqembu elilodwa, elibizwa ngokuthi ama-T-lymphocyte noma ama-T-cell, lifudukela endlaleni ebizwa nge-thymus.

Bethonywe ama-hormone, bavuthwa lapho baba yizinhlobo eziningana zamaseli, kufaka phakathi umsizi, umbulali namaseli acindezelayo. Lezi zinhlobo ezahlukene zisebenza ngokubambisana ukuhlasela abahlaseli bangaphandle. Banikela ngalokho okubizwa ngokuthi yi-immune-mediated immunity, engaphelelwa ngabantu abane-HIV, igciwane elibangela ingculaza. Igciwane lesandulela ngculaza lihlasela futhi libhubhise amaseli T omsizi.

Elinye iqembu lama-lymphocyte libizwa ngama-B-lymphocyte noma ama-B cell. Ziyakhula emnkantsheni wethambo futhi zithole amandla okubona abahlaseli abathile bakwamanye amazwe.

Amaseli avuthiwe B adlulela emanzini omzimba aye kuma-lymph node, ubende negazi. NgesiLatin, uketshezi lomzimba lwalwaziwa njengamahlaya. Ngakho-ke ama-B-cell ahlinzeka ngokwaziwa ngokuthi yi-humoral immune. Ama-B-cell nama-T-cell womabili ajikeleza ngokukhululekile egazini nase-lymph, efuna abahlaseli bakwamanye amazwe.
