Which type of blood cell is involved in the immune response?

Leukocytes, or white blood cells, play a crucial role in the immune response. They are essential components of the body's defense system, tasked with identifying and neutralizing pathogens such as bacteria, viruses, and other foreign bodies. Unlike erythrocytes, which are primarily responsible for transporting oxygen, and thrombocytes, which are involved in blood clotting, leukocytes are specifically designed to recognize and respond to immune threats.

There are several types of leukocytes, including lymphocytes, neutrophils, monocytes, eosinophils, and basophils, each of which has specialized functions in the immune system. For example, lymphocytes include B cells that produce antibodies and T cells that help in cell-mediated immunity. This specialization allows for a versatile and adaptive immune response, enabling the body to better defend itself against infections.

Thus, the involvement of leukocytes in the immune response is foundational to understanding how the body protects itself against disease and maintains overall health.
