Topic: Immunity Aim: Explain some disorders of the immune system. Do Now: Copy topic, aim and HW. HW: Venn Diagram – Passive and Active Immunity PATHOGEN A ANTIGEN C B ANTIBODY 1.Identify structures A, B and C. 2.Describe what occurs when a pathogen enters the body. 3.Identify what produces structure B. 4.What kind of immunity would this provide? Compare and contrast passive and active immunity. COMPARE They BOTH help fight pathogens. They BOTH involve antibodies and antigens. CONTRAST Passive immunity is short-term. Active immunity is long-term. CONTRAST Active immunity occurs when you make your own antibodies. Passive immunity occurs when you RECEIVE antibodies. CONTRAST Vaccines are used to get active immunity. Vaccines CANNOT be used to get passive immunity. CONTRAST You can get passive immunity from your mother. This is not true for active immunity. • Caused by a pathogen Infectious disease • Can be transmitted (passed on) • CONTAGIOUS https://www.youtube.com/watch?v=m-3Ju0EX3gQ How can • By your respiratory diseases system be –Coughing or sneezing spread? –Chickenpox, a cold, influenza, strep throat • During sexual activity (STD’s) –HIV/AIDS: breaks down the immune system • Direct and indirect contact Noninfectious • Not caused by a disease pathogen • CANNOT be transmitted • Allergies • Cancer https://youtu.be/LEpTTolebqo?list=PL69F87388814E7A2F https://www.youtube.com/watch?v=q8sw2FI-_bI • Arthritis • Heart disease • Diabetes • Asthma Identify one example of a noninfectious disease that CAN BE PREVENTED. • Heart disease • Skin cancer • Lung cancer Identify one example of a noninfectious disease that CANNOT BE PREVENTED. • Breast cancer • Leukemia (bone cancer) • Prostate cancer • Pancreatic cancer Let’s summarize…: 1. Identify the type of disease that can be transmitted or spread. 2. Identify the type of disease that CANNOT be transmitted or spread. Infectious diseases are caused by 1. deficiencies in the diet 2. allergies 3. microscopic organisms that can be transmitted from one organism to another 4. malfunctioning organs Resistance to a specific disease is a(n) 1. antibiotic. 2. immunity. 3. white blood cells. 4. addiction Once you have had the chicken pox, it is unlikely that you will ever get the disease again because your body has developed a(n) 1. passive immunity. 2. addiction. 3. active immunity. 4. antibiotic. An injection of a weakened virus that allows one to develop immunity against a disease is called a 1. antibody 2. vaccine 3. epidemic 4. pathogen Which of the following parts of the body's defense system seeks out and destroys bacteria? 1. mucus 2. white blood cells 3. skin 4. red blood cells Immunity that occurs when a body makes its own antibodies is called _________immunity. 1. Passive 2. Temporary 3. Shortened 4. Active Infectious diseases are caused by 1. deficiencies in the diet 2. allergies 3. microscopic organisms that can be transmitted from one organism to another 4. malfunctioning organs A person with AIDS is likely to develop infectious diseases because the virus that causes AIDS 1. destroys cancerous cells 2. damages the immune system 3. increases the rate of antibody production 4. increases the rate of microbe destruction
