Anatomy & Physiology
Lab Week 6: Immune System
Exercise #1
Using the cue cards provided, match the various descriptions to their appropriate
mechanism of defense.
These cue cards are the first column of the table one the last page of the lab. I would
suggest that you print off your own copy & use this exercise as a study tool for the test. It
would also be beneficial for you to construct your own, for understanding the non
specific and specific immune defenses.
Non-Specific Defense Mechanisms (and do matching exercise on last page of lab)
First column is cue card for this part
___________________
- physical impediments to the entry of antigens
___________________
- a continuous wall that separates the internal & external
environments
___________________
- examples are sebum, mucous & enzymes that chemically
inhibit the activity of pathogens
___________________
- isolates the pathogens & stimulates the arrival of large
numbers of immune cells
___________________
- ingest & destroy pathogens
___________________
- granular leukocytes that are usually the first to arrive at
the scene of inflammation
___________________
- monocytes that have enlarged & become phagocytic
___________________
- group of lymphocytes that kill a variety of cancer cells &
cells infected with viruses
___________________
- protein produced by viral infected cells to help protect
other cells
___________________
- group of proteins that produce a cascade of chemical
reactions that ultimately cause lysis of a foreign cell. Can
be triggered by either the specific or non-specific immune
reactions
___________________
- protein that binds iron reducing the amount available to
bacteria therefore inhibiting their growth
Exercise 2:
Write the class of immunoglobulin (Ig) beside each description.
____ the first antibody to be secreted after initial exposure to an antigen
____ found in secretions such as mucous, saliva, tears & breast milk
____ the most abundant Ig & the only one to cross the placenta
____ antigen receptors found on the B cells & activate the B cells (plasma cells) to make
antibodies
____ involved in allergic reaction
Exercise 3:
Describe how vaccines work?
Exercise 4:
Define & give examples of the following:
a) artificially acquired active immunity
b) artificially acquired passive immunity
c) naturally acquired active immunity
d) naturally acquired passive immunity
Match the card on the right with the correct description on the left
Surface membrane barriers
ingest & destroy pathogens
physical impediments to the entry of antigens
Skin & mucosa
Inflammation
examples are sebum, mucous & enzymes
that chemically inhibit the activity of
pathogens
group of lymphocytes that kill a variety of cancer cells
& cells infected with viruses
Phagocytes
protein that binds iron reducing the amount available to
bacteria therefore inhibiting their growth
Secretions
Neutrophils
Macrophage
Natural killer cells (NKC)
Interferon

to arrive at the scene of inflammation
group of proteins that produce a cascade of chemical
reactions that ultimately cause lysis of a foreign cell.
Can be triggered by either the specific or non-specific
immune reactions

help protect other cells
isolates the pathogens & stimulates the
arrival of large numbers of immune cells
