Virus- tiny disease –causing particles made up of a genetic and a protein coat

Fungi– organisms that absorb and use the nutrients of living or dead organisms

Parasite– cause a large number of diseases in the U.S.

Protist– free-living organisms that are more complex than bacteria

4 Ways Infectious Diseases Spread 

Person to PersonSneezing, coughing, sharing drink containers, and having sexual contact can spread diseases from person to person.

Protecting Yourself From Infectious Diseases

How The Body Fights Infectious Diseases To make you sick most pathogens enter your body, start growing, and cause damage. Your body’s first line of defense is your SKIN. Your skin helps keep pathogens from entering your body. Mucous membranes are the soft tissues that line the nose, mouth, throat, and digestive tract. Like the skin, mucous

forms a barrier to keep pathogens out. The last line of defense is Chemicals. Many of the chemicals in your body destroy pathogens. Sometimes pathogens escape the barriers your body throws at them, and that’s where Inflammatory Response comes in. Inflammation ( a reaction to injury that is characterized by

pain or redness, and swelling) is the next way your body fights diseases. You know your body is fighting diseases when the inflammatory response happens. The last way your body fights diseases is with your immune system. Even though mucous barriers and the inflammatory response are very effect

-tive they can’t protect against all pathogens. So your immune system gets ready for action. The immune system is made up of certain types of blood cells and proteins called antibodies. Those lymphatic systems move through your body and pick up fluids from your body.

5 Things You Can Do To Stay Well 1. Drink Water. Drink 8 to 10 glasses of water a day to keep your immune system working properly.
