8 Blood Clotting Platelets rupture, releasing a chemical into the blood. The chemical triggers the formation of protein fibers. The protein fibers trap blood cells, forming a clot. Visual 25-7

11 Splinter Wound Bacteria (green) enter the body on the end of a splinter. Macrophages (purple) squeeze through the capillary walls. As the wound heals, the macrophages finish destroying the bacteria. Visual 25-10

12 Human Immune System macrophage B cells B2 plasma cells T cells B1 bacteria B3 antibodies B5 A1 killer T cells B4 A2 memory B cell A4 A3 infected cell memory T cell The immune response: When macrophages identify a foreign substance (bacteria), two series of events begin to happen simultaneously. T cells activate killer T cells (A1) as well as B cells (B1). Some killer T cells attack the bacteria (A2), and others attack infected cells (A3). Meanwhile, the activated B cells produce plasma cells (B2), which in turn produce antibodies (B3). The antibodies attack the invading bacteria (B4). After the bacteria have been destroyed, some T cells (A4) and some B cells (B5) become memory cells to guard against future infections. Leftover antibodies also remain in the bloodstream, enhancing the body s immunity. Visual 25-11
