SC.912.L.14.52 - The Immune System

These cells are responsible for identifying the "enemy" in an immune response.

• Killer-T Cells
• B Cells
• Helper-T Cells
• Antibodies

What do antibodies attach to on the pathogen?

• Anti inflammatory
• Antigens
• Antiseptic
• Antibodies

Which is NOT considered FIRST line of defense?

• White Blood Cells
• Skin
• Hair
• Mucous Membranes

Which disease is caused by a bacteria?

• Malaria
• The flu
• Strep Throat
• Athlete's foot

Disease-causing microorganism, such as a bacterium or virus.

• pathogen 
• allergen
• prion 
• antigen 

  A substance or part of a substance (living or nonliving) that the immune system recognizes as foreign and activates the immune system and reacts with immune cells or their products, such as antibodies.

• pathogen 
• allergen 
• antigen 
• antibody

What happens first in the inflammatory response?

• macrophages arrive and consume pathogens
• histamine is released by injured mast cells
• arteries to injury dialate
• veins from the injury constrict

What function does mucus play in the immune system?

• traps foreign particles from entering the body
• moistens food
• produces WBCs
• acts as a lubricant

How does immune system fight viruses?

• Immune system guards our body and when red blood cells which are the part of our immune system detect viruses in our body they kill the antigen or viruses by antibodies.
• Immune system guards our body and when 
  white blood cells which are the part of our immune system detect viruses in our body they kill the antigen or viruses by antibodies.
  
• Immune system guards our body and when 
  antibiotics which are the part of our immune system detect viruses in our body they kill the antigen.
• None of above 

which one is not part of cell mediated immunity, specific response?

• Helper T cells
• Cytotoxic T cells
• Suppressor T cells
• Macrophages
