There are several synonyms for the term WBC, which stands for White Blood Cells. These synonyms include leukocytes, immune cells, white cells, and white corpuscles. White Blood Cells play a crucial role in our immune system by fighting off infections and harmful foreign substances in our bodies. They are produced in bone marrow and circulate throughout our bloodstream, constantly monitoring our bodies for threats. When an infection or foreign substance is detected, white blood cells rush to the site and work to eliminate the threat. Understanding these synonyms allows us to communicate more effectively with healthcare professionals and gain a better understanding of our body's defense mechanisms.
