<prompt> Yini efakwe ohlwini? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Isimiso sokuzivikela somzimba esishintshashintshayo savela ezilwaneni ezinomgogodla zakuqala futhi sivumela ukuphendula okuqinile komzimba kanye nenkumbulo yokugomela, lapho igciwane ngalinye likhunjulwa yi-antigen ethile. Impendulo evumelana nezimo iqondene ne-antigen ethile futhi idinga ukubonwa kwama-antigen athile angewona awomuntu phakathi nenqubo ebizwa ngokuthi ukubonakaliswa kwe-antigen. Ukwehluka kwe-antigen kuvumela ukukhiqizwa kwezimpendulo ezenzelwe ama-pathogen athile noma amangqamuzana atheleleke ngama-pathogen. Ikhono lokwenza lezi zimpendulo ezenziwe ngezifiso ligcinwa emzimbeni ngamaseli enkumbulo. Uma igciwane lingena emzimbeni izikhathi ezingaphezu kwesisodwa, la mangqamuzana akhethekile enkumbulo asetshenziselwa ukulikhipha ngokushesha.
