Despre sistemul imunitar

Sistemul imunitar este format dintr-un sistem complex de celule, tesuturi si organe, parte din mecanismul de protectie al organismului. Functionarea acestui sistem se manifesta prin imunitate. Semnificatia termenului "imunitate" este, evident, rezistenta. Functia principala a sistemului imunitar consta in a face distinctia intre substantele proprii organismului si cele straine si in a le indeparta pe cele straine, in cazul in care exista.1

Vitamina C contribuie la functionarea normala a sistemului imunitar, stimuleaza productia de leucocite si imbunatateste functia acestora.2

Atunci cand sistemul imunitar produce anticorpi si lupta, continutul de vitamina C din leucocite se reduce semnificativ. In acest context, cantitatea de vitamina C disponibila in circulatia sanguina pentru a fi utilizata de organism joaca un rol important.3
