cells that fight infections and foreign substances in the body
White Blood Cells (WBCs), also known as leukocytes, are a crucial component of the immune system. They help the body fight infections and other diseases by identifying and destroying pathogens like bacteria, viruses, and foreign substances. There are several types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with specialized functions in immune response.
