What are blood cells that assimilate bacteria and foreign invaders.

There are only three types of blood cells and these are: Red Blood Cells (RBCs), White Blood Cells (WBCs), and platelets. They are the components of the blood that play significant roles in the body.  

White Blood Cells or WBCs are the types of blood cells responsible for assimilating bacteria and foreign invaders in the body. WBCs play a big role in the immune system of the body as these cells help fight infections by attacking viruses and bacteria that enter the body. They are larger in size compared to Red Blood Cells because they are also responsible for the repair of broken tissues in the body. They originate from the bone marrow and they constantly guard and circulate throughout the bloodstream.
