SCI 250 Week 4 Innate Defenses Matrix

Complete the matrix in Appendix E to contrast types of innate host
defenses. Be sure to include specific information about how each can affect the
human body.

Appendix E – Innate Defenses

 

Part One and Part
Two focus on various types of innate defenses against infection. Use Ch. 16 in
your text to help you complete both parts.



PART ONE: Puncture
wound multimedia activity



After completing the Inflammatory Response multimedia activity located at
http://corptrain.phoenix.edu/hhs/SCI250/innate_defenses.html

complete the table below. List the four events of the inflammatory
response covered in the activity in the correct order of occurrence. As you re-write
the events in your own words, add more detail and use terms from Ch.16 of the
text.

PART TWO: TYPES OF
INNATE DEFENSES



The table presents
various innate, nonspecific immune responses to pathogen exposure. Use Ch. 16
to help you identify and describe the type of defense in the Event column.




Event


Type
of Innate Defense



What
is happening in the body during the defense?





It is a very windy day, and you have
inhaled all kinds of particles – from dust to potentially harmful pathogens –
but a quick sneeze prevents you from coming down with an illness.


Physical Barrier


The nose contains mucous, which helps to
flush out microbes and particles when a person sneezes.




A man at a restaurant ingests food
contaminated with microbes that could potentially cause disease. The microbes
do not survive very long in his stomach, so he does not get sick.


 


 




A child gets a small cut on her foot while
running barefoot on the beach. The wound becomes slightly red and swollen.
Her wound does not get infected, but it hurts a little, and it feels a bit
warm.


 


 




Yesterday, you suspected you might be
getting sick. Today, you feel very tired. When you take your temperature, the
thermometer reads 100.2ºF.


 


 




Flesh-eating bacteria are present on your
leg. You do not have any wounds, so you do not become infected in spite of
exposure.


 


 




Your teenage brother has developed a zit
on his forehead. (Hint: Identify two types of defenses, since infection has
occurred.)
