Transcript The Body’s Defenses

The Body’s Defenses
Non-Specific and Specific
Responses to Invaders
Immune System Primer
The Immune System Primer
offers a self-directed study
of the Human Immune
System. It is designed to
give general biology
students basic knowledge
of the various mechanisms
the body employs to
defend itself against
foreign invaders. It
contains links to a number
of on-line animations and
reference materials.


Hepatitis A Scare
Objectives





Identify the role each item plays in fighting an
infection: skin, mucus, saliva, sweat,
phagocytes, natural killer cells, fever, B cells and
T cells
Identify four symptoms of inflammation
Describe the importance of washing one’s hands
Explain how Hepatitis A virus is spread
Compare and contrast T and B cells
Objectives

Define the following terms: adaptive immunity,
antigen, antibody, histamine, immunology, innate
immunity, lymphocyte, pathogen
 Use leucocytes to describe the process of cell
differentiation
 Describe the immune response
 Identify four major types of infectious agents
Objectives

Distinguish between a primary immune
response and a secondary immune response
 Using leucocytes, provide examples of how cell
structure is related to function
 Compare and contrast plasma and memory cells
MA Frameworks

2.1 Relate cell parts/organelles to their function
 2.5 Explain the role of cell membrane as a highly
effective barrier
 4.1 Explain how major organ systems in
humans have functional units with specific
anatomy that perform the function of that organ
system
