Basic Immunology lesson for middle school. I included the blood components to give them a brief background. *You are free to edit if you find this useful to your class.

2. Vocabulary
• Antibodies
• Blood
• Immunoglobulin
• Phagocyte
• Lymphocyte
• Antigens

3. Blood
• Blood is composed of cells
and plasma. The cells include
red blood cells,
and platelets.

4. Components of blood
• Red cells (called erythrocytes)
normally make up 40-50% of the total
blood volume. They transport oxygen
from the lungs to all of the living
tissues of the body and carry away
carbon dioxide.

5. • White cells (called lymphocytes) are
the first responders for our immune
system.

6. • Platelets , or thrombocytes , are cell
fragments without nuclei that work
with blood clotting chemicals at the
site of wounds.

7. • Plasma- is the relatively clear, yellow
tinted water (92+%), sugar, fat,
protein and salt solution which carries
the red cells, white cells, and
platelets.
• It contains nutrients, electrolytes,
hormones and protein antibodies to
fight infection.

8. Antibodies
• Antibodies, also known
as immunoglobulins, are Y-shaped
proteins that are produced by the
immune system to help stop intruders
from harming the body.

9. Phagocyte
• a cell (as a white blood cell) that
engulfs and consumes foreign material
(as microorganisms) and debris
WBC classes- monocyte and neutrophil

10. Lymphocyte
• a form of small leukocyte (white blood
cell) with a single round nucleus,
occurring especially in the lymphatic
system.

11. T-cells
• a lymphocyte of a type produced or
processed by the thymus gland and
actively participating in the immune
response.

12. B-cells
• a lymphocyte not processed by the thymus
gland, and responsible for producing
antibodies.

13. • Antigens are viruses, bacteria, or
other chemicals. When an antigen is
found in the body, the immune
system will create antibodies to mark
the antigen for the body to destroy.
