The common lymphoid progenitor produces either natural killer cells (granular lymphocytes) or small lymphocytes. They have always been associated with parasitic, inflammatory, and allergic immune responses. They need to pass from the circulation, through the vessel wall into the extravascular tissues in order to carry out these functions. While dendritic cells are not phagocytes, they are known to nibble cells, removing and digesting part of the membrane and so killing the cell. Hematopoietic stem cells differentiate into one of two progenitor cell groups the common myeloid progenitor that produces granulocytes and monocytes, and the common lymphoid progenitor that differentiates into lymphocytes. The cells are all prokaryotic. Dendritic cells are important antigen-presenting cells that communicate with a broad range of cell types. Blood carries things you need, like oxygen and glucose, and waste. These two cell types work together, even though basophils only make up around one percent of all white blood cells in the blood and tissues. They are a key factor in asthma pathology. The reticuloendothelial tissues of the spleen, liver, lymph nodes, and other organs produce the monocytes (4 to 8 percent of the white cells). Anemia is a condition characterized by the lack of production of new or healthy red blood cells. B lymphocytes secrete antibodies, which are proteins that bind to foreign microorganisms in body tissues and mediate their destruction. eating| Compare the effect on the host cell of a lytic (virulent) phage and a lysogenic (temperate) phage.

Structure and function of RBC critical to understand: Think and read briefly about Sickle Cell Anemia (sickle shaped) and other RBC disease conditions would include; Hereditary Spherocytosis (ball shaped), or Sideroblastic Anemia (RBC too small). White blood cells - Production of antibodies and killing pathogens Plasma (a fluid that gives liquidity to blood) - It transports carbon dioxide, hormones, carbon dioxide, urea and heat. Your red blood cells also transport carbon dioxide to your lungs for you to exhale. Intermediate monocytes are antigen-presenting cells that also stimulate T cell production, help renew damaged blood vessels, and take part in the inflammatory response. They suck them right up, just like a vacuum cleaner! White blood cells or leukocytes (leukos = white, cytes = cells) are so-called because they are true cells that do not contain the red protein, hemoglobin.The real value of white blood cells is that most are specifically transported to areas of infection, thereby providing a rapid and potent defense against infectious agents. They can differentiate into dendritic cells, macrophages, histiocytes, microglia cells, osteoclasts, and mesangial cells, but as monocytes have their own set of functions. Monocytes, which constitute between 4 and 8 percent of the total number of white blood cells in the blood, move from the blood to sites of infection, where they differentiate further into macrophages. This section looks at their functions. Phagocytes About 70 per cent of white blood cells are phagocytes. A healthy persons WBC count is typically 4,500 to 10,000 per ul of blood. Eosinophils constitute 1% to 4% of the white blood cells.
