The document summarizes key points about the lymphatic and immune systems, allergies, hives, and vaccinations. It explains that allergies involve an exaggerated immune response and lists common allergy symptoms. It describes hives as swollen red bumps or plaques on the skin caused by histamine release, and notes antihistamines are a common treatment. Finally, it defines vaccination as administering antigenic material to stimulate adaptive immunity and notes vaccines often contain adjuvants to boost immune response.

2. Allergy
• is a hypersensitivity disorder of the immune
system
• Hypersensitivity- undesirable reactions
produced
• Immune system- system of biological
structures and processes within an organism
that protects against disease

4. Allergy points
• Allergy involves an exaggerated response of the immune
system.
The immune system is the body's organized defense
mechanism against foreign invaders, particularly infections.
Allergens are substances that are foreign to the body and
can cause an allergic reaction.
• Who is at risk?
– Everyone

5. • Symptoms
– Shortness of breath
– Wheezing
– Coughing
– Chest tightness
• Treatment
– Medication such as allergy shots

6. Hives
• An outbreak of swollen, pale red
bumps or plaques (wheals) on the skin that
appear suddenly

7. Hives
• One will usually have itching and sometimes
burning feeling
• Hives vary in size (from a pencil eraser to a
dinner plate), and may join together to form
larger areas known as plaques.
• They can last for hours

9. Hives
• Response to histamine, blood plasma leaks
out of small blood vessels in the skin.
• Antihistamines are usually prescribed by your
doctor

10. Vaccination
• Administration of antigenic material (a
vaccine) to stimulate the immune system of
an individual to develop adaptive immunity to
a disease.

11. Vaccination
• Vaccines typically contain one or more
adjuvants, used to boost the immune
response. Tetanus toxoid, for instance, is
usually adsorbed onto alum.
• At my job it is highly suggested that we get
vaccinated due to being around patients
