Unit 8: Lymphatic System and
Immune System
Another way to
transport ______ and
________ your body
A. Lymphatic System
- a system of ______ and
______ used to circulate
materials around the
body
- similar to the circulatory
system but it _________
_____________ around
- moves ______________
around the body
mostly water
1. _________________________________________
- a watery fluid used to keep _________________
- if cells are not ________________________________
 the dry cells ______________________________
- lymph fluid is made from the plasma and _______ in the
blood
- lymph fluid constantly ________________________ into
the area around
cells
- cells are bathed
in inter cellular
fluid
2. ___________________
- a tube that is used to ______
_____________ from all over
the body
- very similar to a _____ (it has
_________) but it is different
because one end of the lymph
vessel is open
- open end collects lymph fluid
from around the cells
- moves fluid using blood
pressure, skeletal muscle,
body movement, and valves
3. _______________________
- a collection of __________ on
a lymph vessel
- ______________________
- ___________ _____________
(to start the flow again)
- make a certain type of ______
_________ – _____________
- helps with the immune
system – ______________
B. Immune System
1. _________ – an abnormal condition that impairs the body
functions of an organism
- specific symptoms that ___________________ in the
organism
a) Types of Disease
1) Genetic Disease – something different in the DNA
Sickle Cell Anemia, Cystic Fibrosis
- Congenital Disease – the person is born with the
defect; Congenital Heart Disease
2) Nutritional Disease – caused by a lack of nutrient
Scurvy, Malnutrition, Rickets, Crohn’s Disease
3) Environmental / Behavioral Disease – caused by the
situtation the person is in
Asbestosis, Lung Cancer from Smoking
4) ________________ – ___________________
____________________
diseases caused by pathogens = ______________
_____________________________
Tuberculosis, Influenza, HIV, Tapeworm, Tetnus
2. Human Immunity
a) 1st Line Defense - ___________________________
- Physical and chemical barriers are ways in which your
body stops the pathogen from entering
- Pathogen = disease causing organism
1) ________________
2) ________________
3) ________________
4) ________________
5) ________________
6) ________________
b) 2nd Line Defense – _____________________________
1) blood vessels expand
- ______________________________ – turns red
- ____________
- more _______________________
2) white blood cells gather around area
_____________ = specific type of white blood cells
3) ____________________________________
Non-Specific in its action
c) 3rd Line Defense - _____________________________
1) __________ – _________________________________
- used to _____________ – “I.D. card for the cell”
- every cell ___________________________________
- each person has their own individual set of antigens
______________
______________
______________
______________
2) ________________
- _______________________
- made by ____________ (special white blood cells)
- stick to __________  _________________________
______________________________
- very specific – __________________________________
3) _______________________________
- _______________________________________
- _______________________________________
- it forms clumps = ________________________
- ABO Blood Groups
Why mixing blood can be dangerous?

Blood to:
Can
Receive
Blood from:
4) White Blood Cells
- _______________________________ – engulf pathogens
Express antigens on pathogens – this helps your other
immune system cells identify the bad pathogens
- __________________________ – produce antibodies
Each B cell produced different antibodies specific to each
antigen
- ___________________________ – make huge amounts of
antibodies
- ____________________________ – help B Cells become
activated
- __________________ – T Cells that destroy infected cells
3. Immunity
1) __________________
- injection of an __________________ virus that causes
the body to go through an _______________
- the body makes _______________________________
- when you come in contact with the pathogen, you do
not get sick
- MAKING A VACCINE
- __________________ – scientists have to find out what is
making people sick
- __________________ – scientists want to alter the
pathogen so it will cause you to make antibodies but not
make you sick
1 - _____________________
2 - _____________________
3 - ___________________
__________________
- ______________________
into you to cause an
__________________
Your body has to make
anitbodies
2) ___________________
- _________________________________________
- you have memory cells in case you come in contact with
the same pathogen
- usually you will not get the same virus again
- usually lasts a lifetime
3) ____________________
- you get antibodies from someone or something else
- only last for 2 – 3 months
- Example: ____________________________________
____________________________________________
helps to keep you from getting sick in the first 3 months of
life
C. Immune Diseases and Disorders
1. _______________________
- ______________________
is the pathogen that causes
AIDS
- ______________________
__________________
the body can not protect itself
from other pathogens
- HIV – ____________________
__________________________
- It destroys the ____________ so
that the infected person _______
__________________________
- Most people with AIDS die of
_______________
- Transmitted through bodily fluids
___________________
___________________
___________________
- Many people are _______ that they
are infected
- _________________________ for
years
- _______________
- Currently working to make vaccines
2. _____________________
- The immune system attacks materials ________________
_________________________
dust, sun, pet fur, pollen, peanuts
- The white blood cells release _______________________
Histamines cause itchyness, red eyes, sneezing
3. ________________________________
- Your immune system ______________________________
- examples:
Hashimoto’s disease
Lupus
Multiple Sclerosis (MS)
Rheumatoid Arthritis
- _______________________________
4. __________________
