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.)
