1 31.4 Immunity and Technology Set up Cornell Notes on pg. 77Topic: 31.4 Immunity and TechnologyEssential Question(s):Under what circumstances might antibiotics NOT be useful in treating a disease caused by a pathogen?Summarize: Write out the steps that your immune system takes when you are vaccinated.31.4 Immunity and Technology2.1 Atoms, Ions, and MoleculesKEY CONCEPT Living in a clean environment and building immunity help keep a person healthy.
2 KEY CONCEPT Living in a clean environment and building immunity help keep a person healthy.
3 The risk of getting sick increases when there are many people in one area
4 How do we control the spread of disease? Cleaning suppliesMedicinesVaccinesTechnologies that help to prevent against sickness OR treat people who are sickPg. 76
5 Many methods are used to control pathogens. Antibiotics and antiseptics cause pathogens to burst.
6 Antiseptics kill pathogens outside of the body. do not target specific pathogensexamples include vinegar and soapAntibiotics kill pathogens inside the body.target one specific bacterium or fungusnot effective against viruses
7 Antibiotics are over used and over prescribed!!!!! Leads to antibiotic resistance
8 Antibiotic resistance can cause medicines to become ineffective. Some bacteria develop an immunity to antibiotics.These bacteria spread the gene, making the antibiotics useless.
11 Vaccines also control pathogens and disease. given to prevent illness contain the antigen of a weakened pathogen(contains the dead, weakened, or inactivated pathogen)
12 Vaccination provides immunity. stimulates a specific immune responsecauses memory cells to be producedallows immune system to respond quickly to infectionhas such a fast response, a person will not get sick
