Answers
Answer:
Monocytes and lymphocytes....
Answer:
a monocytes
Explanation:
Monocytes circulate in the blood and become macrophages in the tissues. These cells are very important in alerting the immune system about an infection. Macrophages are scavengers whose job is to engulf or eat up infecting germs and even infected cells. In the bone marrow, granulocytes and monocytes arise from a common precursor under the influence of the granulocyte-macrophage colony-stimulating factor. Monocytes leave the bone marrow and circulate in the blood. After a period of hours, the monocytes enter the tissues, where they develop into macrophages, the tissue phagocytes that constitute the reticuloendothelial system (or macrophage system). Macrophages occur in almost all tissues of the body. Those in the liver are called Kupffer cells, those in the skin Langerhans cells. Apart from their role as scavengers, macrophages play a key role in immunity by ingesting antigens and processing them so that they can be recognized as foreign substances by lymphocytes. pack
