Immune System The Cell Defenders

Maryland Science Content Standard • Select several body systems and explain the role of cells, tissues and organs that effectively carry out a vital function for the organism, such as defense

Objective • Title: • Date: Homeland Security 12/19/2021 • I will explain how the immune system responds to pathogens.

Lesson Question: What role does the immune system have in helping your body maintain homeostasis?

Engage your thinking… Questions: • How many kinds of invaders can each defender cell recognize? • What happens if the defender cell is killed?

Let’s Explore the Skin! http: //www. kidshealth. org/parent/general/body_basics/immune. html We already know that your immune system helps to defend your body against pathogens, but how does this process work? Use the website above and your books (Chapter 5) to answer the following: 1. What immune the response? 2. Explain the two things that T cells do to defend against pathogens. 3. How do B cells ruin a virus? 4. What is the function of an antibody?

Structure and Function of the Immune System • • The main function of the immune system is to fight disease using the immune response. The cells of the immune system can distinguish between different kinds of pathogens. The immune system cells react to each kind of pathogen with a defense targeted specifically for that pathogen. White blood cells (connective tissue) called lymphocytes (specialized cells) come in two varieties…B cells and T cells.

Explain: B Cells and T Cells Use your text (Chapter 5) to complete the Venn diagram to compare/contrast the jobs of B cells and T cells in the immune response.

Explain… The HIV Virus… Use your text (Chapter 5) to answer the following: 1. How does the HIV virus affect the immune system? 2. How long might it take for someone to get sick from the HIV virus? 3. Why are people with AIDS able to live much longer now than in the past?

Evaluate yourself… How does the immune system respond to a virus to maintain homeostasis in the body? Please explain using information from your text and our class investigations.

Evaluate yourself… Can you: • Explain how the immune system responds to pathogens.
