Why is the stomach apart of the first line of defense gastric juices help to kill germs
Why is saliva and mucous apart of the first line of defense lining of nose, mouth and throat – mucous/saliva traps pathogens –chemical in saliva kills germs
What is the Immune system? a combination of body defenses made up of cells, tissues and organs that fight off pathogens and disease
What is the Nonspecific response of the immune system? all purpose defense against germs that have entered the body (inflammation, white blood cells, fever, etc)
What is the specific response of the immune system? specialized defense against germs that survive the nonspecific response
What is immunity? your body’s ability to resist the germs that cause a particular disease (antibodies - vaccinations)
What is the Lymphatic System? secondary circulatory system that helps fight disease and maintain fluid balance in the body
What is the vaccine? a preparation of dead or weakened pathogens injected into the body to cause the production of antibodies
What are White Blood Cells? specialized cells that fight against pathogens
What are the 3 types of blood cells? Killer T Cells, B Cells, Helper T Cells
What do Killer T cells do? attack pathogens directly
What do B Cells do for the Immune System? produce antibodies which aid in immunity
What do Helper T Cells do for the Immune System? helps to activate the B cells to produce antibodies
What 6 Vaccinations should everyone have? Hepatitis B Diphtheria, Tetanus, Pertussis (DTP) HIB (influenza) Measles, Mumps, Rubella (MMR) Varicella (chicken pox) Hepatitis A (in certain areas)

What is infection? a condition that occurs when pathogens enter the body, multiply and damage cells
What is the Contagious Period? the length of time when a disease can spread from person to person
What are the main ways pathogens are spread? Direct contact with infected person (hand shake)*, Indirect contact with infected person (door knob)*, Contact with a vector (an organism such as an insect that transmit the pathogen), food stored improperly, contaminated drinking water
List examples on how to prevent spreading diseases. Good hygiene clean utensils when preparing food do not share utensils/drinking glasses with others Wear appropriate clothing outdoors (ticks, mosquitoes) Avoid contact with contagious people have up-to-date vaccinations for your age
