Arterioles direct blood flow to the capillaries surrounding lung alveoli. An abnormal increase in the number of white cells is known as leukocytosis, whereas an abnormal decrease in number is known as leukopenia. Lymphocytes are especially abundant in lymphoid tissues and play a vital role in immunity, a defense mechanism that fights against specific antigens and builds a memory of these encounters. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. 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. Antigen-presenting cells (APCs) are white blood cells. When their immunoglobulin E (IgE) proteins bind to antigens, the cell releases the contents of its granules into the extracellular space. Basophils are not APCs as they do not express the genes for MHC construction, but they can take up these molecules from dendritic cells during a process called trogocytosis. ( BBC Bitesize) . And vessels that link arteries and veins together mark the antigen for destruction structure of white blood cells bbc bitesize phagocytes, white cells! As living cells, their survival depends on their continuous production of energy. 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.
