White blood cells (WBCs), also known as leukocytes, are formed in the bone marrow. This soft tissue inside your bones is responsible for producing all types of blood cells, including WBCs.
WBCs are essential for the immune system, defending the body against infections and diseases. Different types of WBCs have specific roles in fighting off pathogens.
Bone marrow is a crucial component of the hematopoietic system, the body's blood-forming system. It constantly produces new WBCs to replace those that die or are used to fight infections.
