Answer:

Fighting diseases.

Explanation:

Leucocytes/White blood cells help to defend the body against diseases.

They are much more larger than red blood cells and are nucleated(having a nuclei or nucleus).

Most importantly, they are formed in the BONE MARROW and some lymph nodes. Sadly, their life span lasts only for few days compared to the Erythrocytes which stays for about three months before they're worn out.

Peace.
