• Directions:
– Take 10 minutes to preview the notes on your own
– Red writining= write down in your notes
– After you have previewed the notes try to answer the question:
How are the white blood cells used to maximize protection
against foreign pathogens? In your answer make sure to explain
the different types of white blood cells.
Function of the Immune System
Organs of the Immune System
• The immune system is also
called the lymphatic system
because it creates and processes
lymph.
• Lymph is any substance that
enters the lymph capillaries.
• Substances enter the lymphatic
system through the lymph
capillaries which are located
right by the capillaries of the
circulatory system.
• The purpose of lymph is to move foreign
particle to the lymph nodes where they can be
destroyed.
• The lymphatic vessels are just like veins and
are used to transport lymph
• Lymph nodes are the main organs of the
lymphatic system. They are made of units
called lymphatic nodules which contain large
amounts of macrophages and lymphocytes.
• The two larger organs of the lymphatic system
are the Thymus and the Spleen.
The role of the skin in the immune
system
• The skin acts as the first line of defense
against pathogens entering the body
• Creates a physical barrier- pathogens have a
hard time penetrating the skin
• Creates a chemical barrier- pathogens killed
by oils and acids on the skin
What carries out the function of the
immune system?
• Leukocytes- White blood cells
• Divided into two big groups
– Granular
– Agranular
•
Granular
• Look like they have grains in their cells under a
microscope
Types of Granular Cells
1. Neutrophil- Phagocytizes (eats) small
particles
2. Basophil- Kill parasites (something that lives off
of another organism) and control inflammation
3. Eosinophil- Release heparin (prevents blood
clots) and histamines (increase blood flow to
injured tissue)
Agranular
• Do not look like they have grains in their cells
under a microscope
Types of Agranualr Cells
1. Macrophage- Phagocytizes
(eat) large particles
2. Lymphocyte- Provides
immunity by creating
antibodies
3. Monocytes- respond to the
inflammation process and are
cells that can turn into a
macrophage.
• Neutrophils are the most prevalent making up
over half of the white blood cells.
• Lymphocytes are the second largest group
followed by macrophages.
• There are very small amounts of the other
two.
Homework Questions
1. What is the function of the immune system and
what structures of the body are involved with
the immune system?
2. Why is the skin considered the first line of
defense for the immune system?
3. Identify and explain the function of the 3 types
of granular and agranular cells.
4. Why do you think neutrophils are the most
common type of white blood cell? Do you think
there is an advantage to neutrophils being the
most common type of white blood cell?
