White Blood Cell (WBC)
  1. Leucocytes
    1. made in the bone marrow
      1. have a nucleus
        1. generally larger than RBCs
          1. either spherical or irregular in shape
            1. main function
              1. fight against diseases
              2. two main groups
                1. Phagocytes
                  1. protect the body by ingesting (phagocytosis) harmful foreign particles, bacteria, and dead or dying cells.
                    1. neutrophils
                      1. short-lived
                        1. 60% of total WBC
                        2. macrophages
                          1. long-lived
                            1. Develop from monocytes
                          2. Lymphocytes
                            1. smaller than phagocytes
                              1. Of two types
                                1. B cells
                                  1. plasma cells
                                    1. antibodies

                                    3. T cells
                                      1. killer T cells
                                        1. helper T cells
                                      2. large nucleus,
                                        1. fills up most of the cell
