Surgical technologists and technicians are a critical part of surgical teams in hospitals and clinics. The surgical supply technician is a surgical technician who is specifically responsible for providing sterile instruments to the team. In some settings, a surgical supply technician is sometimes referred to as a central service technician or a sterile supply technician.
White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All white blood cells are produced and derived from multipotent cells in the bone marrow known as hematopoietic stem cells.
Human blood actually contains three different classes of cells: red blood cells for carrying oxygen, five types of white blood cells for fighting infection and platelet cells for wound clotting. As such, each type of cell has its own lifespan, from a few hours to several decades.
