Which structure is made by the human immune system to fight a pathogen?

• the antibody

• the antigen

• the pathogen

Organ transplants will cause an immune response in the body because...

• red blood cells will be prevented from carrying oxygen.

• antibiotics will be produced that cause blood clotting.

• white blood cells will react to the foreign antigens on the organ.

• the organ prevents antibodies from being made.

Which of the following is FALSE about antibodies?

• They are Y-shaped proteins.

• They are made by the immune system.

• They can attack any antigen that enters the body.

• They remain in the bloodstream for a long time after they are produced.

Thee large green structure with the antigen on its surface is a (an)

• antibody

• pathogen

• enzyme

• hormone

​ (a)   ​ ​produce ​ ​ (b)   and ​ (c)   engulf ​ (d)  

• lymphocytes

• antibodies

• phagocytes

• pathogens

Antibody creation is ​ (a)   to the antigen.

Phagocytes attacking foreign invaders are a​ (b)   ​response.

• very specific

• non-specific

• not affected by

• not related

• feedback

There are two types of immune system responses. One type are responses that are big responses that affect everything in their path. The other type are targeted at one invader at a time. These two different categories of immune defense are ________________

• Non-specific and Specific

• Nasal and Mucous

• Perforin and Protein

Your second line of defense involves a certain type of white blood cell that circulates around your body in the bloodstream. In this 2nd line of defense, NON-specific response what is the FIRST type of white blood cell involved?

• mast

• memory -T

• plasma

• skin

Mast cells release a chemical that causes the blood vessels to dilate, which makes the walls of the blood vessels thinner. What is this chemical called?

• mucous

• perforin

• histamine

• antigen

Once the blood vessels are dilated and the walls are thinner, it makes it easier for some other cells to leave the bloodstream. Which type of white blood cell can now get out?

• mast

• memory-T

• plasma

• macrophage
