Blood Types

What is the basis of the ABO and Rh blood groups?

• Blood pressure

• Rh factor, Antibodies, Antigens, Agglutination

• Heart rate

• Blood sugar levels

What is an antigen?

• A genetically determined protein on the surface of our cells

• A type of antibody found in plasma

• A type of blood cell

• A foreign substance that the immune system ignores

How does our immune system respond to antigens?

• It ignores them

• It recognizes our antigens and responds to foreign antigens

• It destroys all antigens

• It produces more antigens

What are the types of antigens in blood typing?

• A antigens and B antigens

• A antigens and C antigens

• B antigens and C antigens

• A antigens and D antigens

Where are antibodies found?

• In the plasma

• On the surface of red blood cells

• In the nucleus of cells

• In the mitochondria

What do antibodies do?

• Bind to RBCs with the wrong antigens

• Destroy all cells

• Produce more antigens

• Ignore foreign substances

What happens when antibodies bind to RBCs that contain foreign antigens?

• The RBCs multiply rapidly.

• The RBCs undergo agglutination.

• The RBCs become larger.

• The RBCs change color.

What is the potential danger of agglutination in the body?

• It causes the blood to become too thin.

• It can cause blockage of small blood vessels.

• It increases the oxygen-carrying capacity of the blood.

• It makes the blood flow faster.

What happens to RBCs during agglutination?

• They break down and release hemoglobin.

• They become more flexible.

• They increase in number.

• They change shape.

What can the release of hemoglobin in the blood cause?

• Improved kidney function.

• Further blockage of the kidneys.

• Increased blood pressure.

• Enhanced immune response.
