RBCS and One Neutrophil

RBCS and Small Lymphocyte

Clotting Process

Antigens are attacked by your WBCs and antibodies and include: Pathogens (bacteria, viruses, protozoa, etc.) Cancer Cells Non-Self Antigens (not normally found in your body) Includes “foreign” antigens from others that are introduced into the body through blood transfusions or organ transplants.

QOD: What materials does the plasma transport throughout the body?

Whodunit Lab Heads up: 1. Agglutination is clumping/clot formation of red blood cells. 2. Agglutinogens are antigens. 3. Agglutinins are antibodies. 4. Evidence of agglutination is a cloudy appearance to the mixture in the well after being stirred vigorously.

Rh System

Rh + PLASMA RBC Rh Rh Rh Rh

Rh - No anti-Rh antibodies in Plasma RBC

Hemolytic Disease An injection of anti-D antibody is given to Rh+ women immediately after the birth of the baby (the parents are too preoccupied with the new arrival to notice!). The injection contains antibodies to Rh factor, which destroy any of the baby’s blood cells that may have entered the woman’s bloodstream before they have a chance to sensitize her.
