Forensic Science Chapter 8 Vocabulary

clumping of cells caused by an antigen—antibody response

• antigen

• agglutination

• reaction in which antibodies attach to specific antigens; causes agglutination in cross blood-type transfusions

• blood drop created solely as a result of gravity

angle at which blood strikes a target surface relative to the horizontal plane of the target surface

• area of convergence

• satellite

• angle of impact

• area of origin

proteins secreted by white blood cells that attach to specific antigens

• antibodies

• antigen–antibody response

two-dimensional view of the intersection of lines formed by drawing a line through the main axis of at least two drops of blood that indicates the general area of the source of the blood spatter
