Natural Immunity

Question 1

What are Antibiotics?

Answer 1

Produced by microbes to compete with other microbes

Question 2

What are Antibodies?

Answer 2

Produced by immune system to attack foreign objects and make them more “visible”for destruction to phagocyte cells

Question 3

What are Cytokines?

Answer 3

cause swelling, redness, and local heating

Question 4

What are Chemokines?

Answer 4

Attract Neutrophils

Question 5

What are Major Histocompatibility Complexes?

Answer 5

Antigen presenting molecules produced in phagocytes, infected host cells, or B cells. Present pathogens that trigger responses to the rest of the immune system.

Question 6

What are T Cell Receptors?

Answer 6

Membrane spanning proteins on T cells that recognize and bind protein antigens attached to MHCs

Question 7

What is an Antigen?

Answer 7

Molecule on the outer surface of an organism/cell

Question 8

What are the 3 Functions of Antibodies?

Answer 8

1. Tag foreign cells so phagocytes can more easily recognize and destroy. 2. Neutralize effects of pathogens though binding. 3. Aggregate together so they can be found easier

Question 9

What is the Complement System?

Answer 9

Proteins and Antibodies working together. Phagocytosis is enhanced by proteins binding to antigen-antibody complexes. Also form pores in membrane of invaded cell that lead to cell death

Question 10

What is Immediate Hypersensitivity?

Answer 10

Overstimulation of IgE antibody production, over-release of histamines, allergic reaction

Question 11

What are Autoimmune Diseases?

Answer 11

When the immune system makes particles that mistake host cells for foreign cells and try to destroy it
