Immune System- Immune Responses

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

Skin and mucous are your body's first line of defense against invaders. Their job is to keep out anything that is from the outside. This type of defense is

• specific.

• non-specific.

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

NGSS.MS-LS1-3

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

Macrophages are really cool. they have the ability to shape-shift. They can surround the invading pathogens and ______.

• eat them.

• push them out of the body.

• make them leave by telling really bad jokes.

Because macrophages are not picky about what they eat as long as it is an invader, this type of response is

• specific

• non-specific.

Your third line of defense includes two types of immune response that are "specific" because when they respond, they respond to a "specific" invader.

Which of the "specific" responses involves a cell called a Cytotoxic T-Cell?

• cell-mediated

• humoral

Which type of "specific" immune response involves B-cells that are in charge of making antibodies.

• cell-mediated

• humoral

The cell-mediated and humoral responses are both specific immune responses because they target specific invaders. Something they have in common is that they both involve cells that keep a memory of the invader. These cells trigger the immune system to respond quickly if the invader ever returns.

• memory cells

• antibodies

• mast cells

• cytotoxic T-cells
