The polynuclear ne fararen jini (ko leukocytes), sabili da haka ƙwayoyin garkuwar jiki.

Akwai nau'ikan sel fararen jini da yawa, gami da:

• da polynuclear, don haka suna saboda sun bayyana suna da nuclei da yawa
• da mononucleaires, wanda ya hada da "kayan aiki guda ɗaya"Da"lymphocytes«

Kwayoyin polynuclear sune sel waɗanda ke yawo a cikin jini kuma a zahiri suna da cibiya mai yawa. A ciki, suna ƙunshe da “granulations”, waɗanda ke ɗaukar launuka daban -daban lokacin da aka fentin su da fenti na musamman. Don haka mun bambanta:

• neutrophils, waɗanda girmansu ya riƙe abin da ake kira dyes na tsaka tsaki (launin shuɗi)
• eosinophils, waɗanda manyan abubuwan farin ciki suka juya orange
• polynuclear basophils, waɗanda ke ɗauke da manyan ja-ja

Waɗannan ƙwayoyin salula suna tafiya zuwa shafuka a cikin jiki inda akwai kamuwa da cuta ko kumburi. Wannan ƙaura yana faruwa ne a ƙarƙashin rinjayar ƙwayoyin sunadarai waɗanda ƙwayoyin cuta ke fitarwa ko kuma ta jawo su, wanda ke jawo su zuwa wurin “daidai”.

Polynuclear neutrophils sune mafi yawan sel polynuclear: suna wakiltar yawancin sel fararen jini da ke yawo cikin jini (50 zuwa 75%). A matsayin nuni, adadin su ya bambanta daga 1,8 zuwa biliyan 7 a kowace lita na jini (watau 2000 zuwa 7500 neutrophils a mm³ na jini).

Da zarar cikin nama mai cutar, neutrophils suna iya “phagocytize” (wato, hadiye, ta wata hanya) barbashi na waje.
