Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about: The Immune System and Disease

Level#1: Sometimes pathogens succeed in entering the body. If this happens, the immune system tries to destroy the pathogens. The immune system makes antibodies to fight against them. If the correct antibodies are present when a pathogen enters the body, then the person may not get sick.

1. What do pathogens sometimes succeed in doing?





2. What happens if pathogens succeed in entering the body?





3. What does the immune system do when it finds pathogens?






Level#2: Sometimes pathogens succeed in entering the body. If this happens, the immune system tries to destroy the pathogens. The immune system makes antibodies to fight against them. If the correct antibodies are present when a pathogen enters the body, then the person may not get sick. Vaccinations are a way to prevent certain diseases. When you were young, you were probably vaccinated against smallpox, measles, and other diseases. When you are vaccinated, your body develops antibodies against the dead or weak germs before the stronger, more serious germs attack.

1. What do pathogens sometimes succeed in doing and what happens if they do?






2. What does the immune system do to fight against pathogens and what happens if the correct antibodies are present?







3. Why are vaccinations used?







Level#3: Sometimes pathogens succeed in entering the body. If this happens, the immune system tries to destroy the pathogens. The immune system makes antibodies to fight against them. If the correct antibodies are present when a pathogen enters the body, then the person may not get sick. Vaccinations are a way to prevent certain diseases. When you were young, you were probably vaccinated against smallpox, measles, and other diseases. When you are vaccinated, your body develops antibodies against the dead or weak germs before the stronger, more serious germs attack. Scientist have created vaccines for a variety of diseases, including polio, measles, chickenpox, and the flu. There are many more vaccines available today than there were years ago. The development of these new vaccines has meant that many diseases can be prevented. in fact, some diseases no longer exist because of vaccines.

1. Explain what happens if pathogens succeed in entering the body, how does the immune system respond to this, and what does the immune system do to try and fight pathogens.








2. Explain what happens when the body has the correct antibodies when a pathogen enters the body.






3. Explain the purpose of a vaccination.
