1. WELCOME TO BIOLOGY EOC BOOTCAMP

2. BIO EOC CAMP: IMMUNE SYSTEM

3. Immune System and Disease Fighting Infectious Disease
Acquired Immunity

4. Leukocytes & the Immune System
Fighting Illness
Leukocytes & the Immune System
2 responses:
Specific– direct; targeted; go after a specific pathogen; lag time (vaccines & antibiotics)
Nonspecific – general; inflammation; immediate

5. 3 lines of defense
FIRST LINE OF DEFENSE: Skin, Mucus membrane, Saliva, Stomach acid…
SECOND LINE OF DEFENSE: Inflammatory response brought on by Histamines; includes
FEVER = slows down/stop growth of pathogen
PHAGOCYTES = Ingest bacteria (phagocytosis)
INTERFERON = Inhibits virus replication
THIRD LINE OF DEFENSE: (SPECIFIC)
B CELLS = Make antibodies (memory cells)
T CELLS = Attack and Kill
ANTIBODIES = Attaches to antigen and mark them for death

6. 2nd Line of Defense: Phagocyte
phagocytosis.

7. Fighting Illness: Bacteria vs. viruses
Session 5
Fighting Illness: Bacteria vs. viruses
Bacteria – are LIVING and can be killed (antibiotics)
Viruses – are NONliving and canNOT be killed (can only treat symptoms and try to prevent infection)

17. Population Dynamics and Human Impact

18. Vocabulary Review Emigration= number of organisms EXITING a population
Immigration= number of organisms going INTO a population

19. Predator-Prey Relationships
Predators eat prey
As one increases, the other will decrease shortly after and vice versa
Predator-prey graphs always show fluctuation (up and down)

20. Carrying Capacity
The maximum number of individuals an ecosystem can sustain

21. Human Impact Human activities often pollute the environment
Why is this bad??? Because it DECREASES BIODIVERSITY
Biodiversity is having variation (differences) among living things. It’s a good thing!
More biodiversity = healthy and MORE STABLE ecosystem
Human activity often involves polluting environments: this can cause one species to take over while the rest decline, or it could cause the carrying capacity of the ecosystem to decrease. Human activity can also introduce invasive or non-native species. This species may compete with a native species and use up the resources that they need. Human activities often DECREASE the biodiversity of an ecosystem. Biodiversity is GOOD! More biodiversity = healthy and MORE STABLE ecosystem.

22. Human Impact
Human activities can also bring invasive (or non-native) species into an ecosystem
Why is this bad??? BIODIVERSITY AGAIN!
Remember the rabbits in Australia…
Human activity often involves polluting environments: this can cause one species to take over while the rest decline, or it could cause the carrying capacity of the ecosystem to decrease. Human activity can also introduce invasive or non-native species. This species may compete with a native species and use up the resources that they need. Human activities often DECREASE the biodiversity of an ecosystem. Biodiversity is GOOD! More biodiversity = healthy and MORE STABLE ecosystem.

23. Human Impact
Human impact can also use up the natural resources in an area
Deforestation
This can cause the carrying capacity of animal and plant populations to DECREASE
What’s carrying capacity again?
