Document Summary

Defenses our body has to address pathogen (not to specific pathogen) Skin, depends on being unbroken, healthy nutrition maintains turnover. Mucous membranes, nasal and pubic hairs, cilia, eyelashes. Secretions: sebum of skin, saliva, tears, acid in gut, genital. Histamine release from mast cell swelling (to contain infection or injury) Cytokines: provides msges to immune system to kick in. Can be harmful, but paradoxically it can be protctive. Increased body temp (by one or two degrees) kills many agents and increases white blood cell activity. The process of priming the body to remember an encounter with a specific antigen. Get the body to remember how to deal with a pathogen. Body produces own way to recognize and deal with specific pathogen (memory to get rid of it) Antibodies are made by another organism (natural-breast milk) Occurs with injection of antibodies or tranfer of antibodies from mother to fetus across placenta or to newborn in breast milk (conferred)

Host Defenses Activity

Our ability to fight off infection is three fold. Below is a list of terms that deal with our defenses. Match the definition with the terms on this sheet and then fill in the attached diagram with the terms below.

Matching Definitions

A. immunity present at birth, provide nonspecific resistance to infection
B. Adaptive immunities: Immunity that develops after the interaction of antigens with the immune system
C. Many different types, involved in cell-to-cell contact or CMI
D. barrier that blocks invasion at the portal of entry
E. Protective cells and fluids; inflammation and phagocytosis
F .Acquired with exposure to foreign substance; produces protective antibodies and creates memory cells
G. Skin and mucus membranes
H. Bile, stomach acid, skin pH, lysozyme
I. Surveys tissue and discover microbes and dead or injured cells and removes them
J. 26 blood proteins that work to destroy bacteria and viruses
K. Rubor, tumor, calor, dolor
L. Initiated by circulating pyrogens which reset the hypothalamus to inhibit the growth of microbes
M. Responsible for AMI and production of antibodies

1.List the steps of the immune response in the correct order, fromfirst to last. (First, Second, Third)

The immune system develops proteins called antibodies that fightthe infection by killing the antigens.	Choose... Third First Second
The immune system identifies antigens.	Choose... Third First Second
The body saves some antibodies so they are available to fight offthe same disease if exposed again.	Choose... Third First Second

2.Match each item with the correct "line of defense" it isclassified under. (Surface Barrier, General Defense, ImmuneResponse)

lysozyme	Choose... Surfacebarriers Generaldefenses Immune responses
inflammation	Choose... Surfacebarriers Generaldefenses Immune responses
lymph nodes	Choose... Surfacebarriers Generaldefenses Immune responses
B cells and T cells	Choose... Surfacebarriers Generaldefenses Immune responses
unbroken skin	Choose... Surfacebarriers Generaldefenses Immune responses
Antibodies	Choose... Surfacebarriers Generaldefenses Immune responses

3.What is the role of histamine in the inflammatory response?

Chooseone answer.

	a. Itdestroys bacteria by a process called "cell-eating."
	b. Itproduces a fever and lethargy, so energy can be reserved forbattling the illness.
	c. It formsblood clots in the damaged area.
	d. Itdilates blood vessels to make more room for the body's defensive agentsin the injured area.

4.Match each item with the correct description. (Antigen, Prion, Blymphocyte, Macrophage)

An infectious particle that consists only of protein	Choose... Antigen Prion Blymphocyte Macrophage
A white blood cell that engulfs and destroys foreign material, such asbacteria	Choose... Antigen Prion Blymphocyte Macrophage
Any substance that instigates a response by the immune system	Choose... Antigen Prion Blymphocyte Macrophage
A white blood cell that can make antibodies	Choose... Antigen Prion Blymphocyte Macrophage

5.Who is credited with designing the first vaccine?

	a. LinusPauling
	b. EdwardJenner
	c. JonasSalk
	d. StanleyMiller

6.The flu (influenza) vaccine is generally administered as aninjection, often referred to as the flu shot. Can the flu shot giveyou the flu?

	a. No,because the flu shot is a live, attenuated vaccine.
	b. Yes,because the flu shot is a live, attenuated vaccine.
	c. No,because the flu shot is an inactivated vaccine.
	d. Yes,because the flu shot is an inactivated vaccine.

7.Getting a vaccine is similar to getting the actual disease insome ways. For example, when you get a vaccine, yourimmune system produces antibodies that will protect you from future exposures tothe actual disease.

True or False?

8.Getting a vaccine is NOT similar to getting the actual disease insome ways. For example, when you get a vaccine, you should notexperience outward symptoms of the disease you were vaccinatedagainst.

True or False?

9.Numerous scientific studies have shown that there is NO LINKbetween vaccines and autism.

True or False?

please keep answers short

no google

best answer will recieve 5 stars
