  1. Catalyst # 2 Pg. 7-Take out your HW Questions What is a prokaryote? 2. What is a virus? 3. How does a virus infect an individual? (lytic cycle) 4. What are 2 examples of human viral diseases?

  2. Get Ready For Notes Pg.8-9 • Behavioral Expectations: • Noise Level 0: Silent • Head Up • Facing Forward • Directions: • Take 10 minutes to preview the notes on your own • Red writining= write down in your notes • After you have previewed the notes try to answer the question: How are the white blood cells used to maximize protection against foreign pathogens? In your answer make sure to explain the different types of white blood cells.

  3. Function of the Immune System • Protect the body from pathogens (foreign/harmful diseases)

  4. Organs of the Immune System • The immune system is also called the lymphatic system because it creates and processes lymph. • Lymph is any substance that enters the lymph capillaries. • Substances enter the lymphatic system through the lymph capillaries which are located right by the capillaries of the circulatory system.

  5. The purpose of lymph is to move foreign particle to the lymph nodes where they can be destroyed. • The lymphatic vessels are just like veins and are used to transport lymph

  6. Lymph nodes are the main organs of the lymphatic system. They are made of units called lymphatic nodules which contain large amounts of macrophages and lymphocytes.

  7. The two larger organs of the lymphatic system are the Thymus and the Spleen.

  8. The role of the skin in the immune system • The skin acts as the first line of defense against pathogens entering the body • Creates a physical barrier- pathogens have a hard time penetrating the skin • Creates a chemical barrier- pathogens killed by oils and acids on the skin

  9. What carries out the function of the immune system? • Leukocytes- White blood cells • Divided into two big groups • Granular • Agranular

  10. Granular • Look like they have grains in their cells under a microscope

  11. Types of Granular Cells • Neutrophil- Phagocytizes (eats) small particles • Basophil- Kill parasites (something that lives off of another organism) and control inflammation • Eosinophil- Release heparin (prevents blood clots) and histamines (increase blood flow to injured tissue)

  12. Agranular • Do not look like they have grains in their cells under a microscope

  13. Types of Agranualr Cells • Macrophage- Phagocytizes (eat) large particles • Lymphocyte- Provides immunity by creating antibodies • Monocytes- respond to the inflammation process and are cells that can turn into a macrophage.

  14. Neutrophils are the most prevalent making up over half of the white blood cells. • Lymphocytes are the second largest group followed by macrophages. • There are very small amounts of the other two.

  15. Homework Questions • What is the function of the immune system and what structures of the body are involved with the immune system? • Why is the skin considered the first line of defense for the immune system? • Identify and explain the function of the 3 types of granular and agranular cells. • Why do you think neutrophils are the most common type of white blood cell? Do you think there is an advantage to neutrophils being the most common type of white blood cell?

  17. Check For Understanding • How are the white blood cells used to maximize protection against foreign pathogens? In your answer make sure to explain the different types of white blood cells. • Go to m.socrative.com • Enter the classroom number 815058 • Answer the question labeled: • Anatomy: Lesson 58-1/21-1/22- Check For Understanding

  18. Let’s Look At These Cells In Action!Pg. 10 • GO TO: Anatomy: Lesson 58-Inflammatory Response Demo-1/21-1/22 • BEAVIORAL EXPECTATIONS: • Noise Level 2- I can’t hear you from across the room • Elbow Partner ONLY • Assigned Seats • Head Up • Seated

  19. Practice What You Know:Cartoon Maker • BEHAVIORAL EXPECTATIONS: • Noise Level 1- Whisper • Elbow Partner ONLY • Facing Forward • Head Up • DIRECTIONS: • Go to http://www.readwritethink.org/files/resources/interactives/comic/ • Create a title for your comic • Choose 6 panels • Create a comic strip that shows your understanding of the functions of the following immune system cells • Neutrophil • Basophil • Eoisphil • Macrophage • Lymphocyte • Use the last box of your comic to summarize the importance of the immune system • Take screen shot and send to my email at hsaanatomy10@gmail.com • Time stamp by 10:30
