Immune

1. Assign Yourself: Immune System
Practice Questions
• Do Now:
• Match the correct system with the definition

2. Immune and Integumentary Systems

3. What is the largest organ in your body?

4. What is the largest organ in your body?
• Skin!

5. What is the integumentary system?
• The integumentary system includes:
– Skin (epidermis)
– Sweat glands
– Oil glands
– Hair
– Nails

6. What are the functions of the integumentary system?
1. Protection: Skin is a water-proof barrier that
protects you from injury and keeps out harmful
microorganisms (like bacteria) and chemicals.
2. Temperature control: sweats to cool you off, and
raises goose bumps to try to warm you up.

7. What are the functions of the integumentary system?
3. Sensory organ: cells in your skin can sense pressure,
temperature, and pain, and they send messages
through sensory neurons to the brain.
4. Excreting (getting rid of) wastes, like extra salt, by
sweating.

8. What causes different skin colors?
• A pigment (colored molecule) in skin called melanin
protects us from harmful UV radiation from the sun.
• The more melanin there is, the darker the skin is.

9. What is the function of the immune system?
• Protects the body from disease
• 1st line of defense = the skin
• 2nd line of defense = white blood cells

10. Processing Piece:
• Draw a picture to illustrate the body’s 2 lines of
defense against infection.

11. What are 2 types of blood cells?
1) Red blood cells:
– Carry oxygen using a protein called hemoglobin
– Have no nucleus

12. What are 2 types of blood cells?
2) White blood cells
- Part of the immune system
- Includes T cells and B cells

13. What are B cells, and what do they do?
• They are produced in Bone marrow (B for bone)
• They produce antibodies: Y-shaped proteins that
bind to pathogens (organisms that cause disease)

14. What do antibodies do?
• Antibodies stick to bacteria and other pathogens.
• White blood cells called phagocytes come and eat
the pathogen.
• Eating another cells is called “phagocytosis.”

15. Phagocytosis

16. Processing Piece:
• Draw a picture to illustrate the following:
– A B cell makes antibodies
– Antibodies stick to pathogens
– “Phagocytosis” is when white blood cells eat
pathogens that have antibodies stuck to them.

17. What are T cells, and what do they do?
• They mature in the thymus (T for thymus)
• Killer T cells (called CD8 T cells) kill infected cells
and cancer cells with enzymes that make the cell
break apart
• Helper T cells (called CD4 T cells) help the B cells
and killer T cells do their job by activating them.

18. What are memory T and memory B cells?
• Memory cells “remember” pathogens that have
made you sick before. Then, if that pathogen ever
infects you again, the memory cells immediately
attack it.
• This is how a vaccine works – it teaches memory
cells to recognize a pathogen.

19. Processing Piece
• Draw a picture to illustrate the following:
– Killer T cells kill infected cells and cancer cell
– Helper T cells activate other immune cells
– Memory cells remember pathogens that have
made you sick before

20. What are lymph nodes?
• Places in where white blood cells hang out.
• They become swollen when you have an infection.

21. How does HIV cause AIDS?
• The HIV virus infects and kills helper (CD4) T cells

22. Processing Piece:
• In the drawing you made before, show which kind
of cell HIV targets.
• Also show which cell a vaccine helps with.

2. What is the body’s 1st line of defense against
against infection?
3. What kinds of immune cells fight infections?
4. How does HIV cause AIDS?
