Leukocytes

Leukocytes, or white blood cells, are a vital part of the immune system. They help defend the body against infections and diseases by identifying and attacking harmful organisms like bacteria and viruses. There are several types of leukocytes, each with specific roles, such as fighting infections, producing antibodies, and coordinating the immune response. Unlike red blood cells, which carry oxygen, leukocytes are larger and less numerous. They travel through the bloodstream and can migrate to tissues to protect the body. Maintaining a balanced level of leukocytes is crucial for good health and fighting off illnesses.
