Iiseli ezimhlophe zegazi ezikhethekileyo ezibizwa ngokuba zii-lymphocyte zidlala indima ebalulekileyo ekuphenduleni amajoni omzimba kubahlaseli bangaphandle. Kukho amaqela amabini aphambili, omabini lawo enza kumongo wethambo.
Elinye iqela, elibizwa ngokuba yi-T-lymphocyte okanye ii-T-seli, lifudukela kwidlala elibizwa ngokuba yi-thymus.
Bephenjelelwa zihormone, bayavuthwa apho kwiindidi ezininzi zeeseli, kubandakanya umncedisi, umbulali, kunye neeseli zokucinezela. Ezi ntlobo zahlukeneyo zisebenza kunye ukuhlasela abahlaseli bangaphandle. Banikela ngento ebizwa ngokuba kukuzikhusela komzimba okuneseli, okunokusilela kubantu abane-HIV, intsholongwane ebangela uGawulayo. Intsholongwane kaGawulayo ihlasela ize itshabalalise iiseli ezincedisayo zeT.
Elinye iqela leelemphocyte libizwa ngokuba zii-B-lymphocyte okanye ii-B cells. Bayakhula kumongo wethambo kwaye bafumane amandla okuqonda abahlaseli abathile bangaphandle.
Iiseli ze-B ezikhulileyo ziyahamba zihamba emzimbeni womzimba ziye kwii-lymph node, spleen, kunye negazi. NgesiLatin, ulwelo lomzimba lwalusaziwa ngokuba ziihlazo. Ke ii-B-cell zibonelela ngento eyaziwayo njengesiqhulo sokuzikhusela. Iiseli ze-B kunye neeseli ze-T zombini zijikeleza ngokukhululekileyo egazini nakwi-lymph, zikhangela abahlaseli bamanye amazwe.
