Caption: Blood monocyte and phagocytosis of a dying red blood cell. Monocytes are derived from bone marrow monoblasts and promonocytes. A monocyte is a circulating phagocyte that ingests microbes, invading particles, cellular debris and dying red blood cells. They are delivered to the blood and can enter the tissues to develop into macrophages.
