which type of pathogen causes typhoid fever?
a disease causing agent
a disorder in which some of the body's own cells lose the ability to control growth
the body's ______ line of defense is to keep pathogens away from the body by using the skin, mucus, tears, sweat...
the body's ______ line of defense is the inflammatory response
the body's reaction when a pathogen enters the body, millions of white blood cells are produced to fight the infection. The white blood cells get rid of the bacteria, and the tissue that is infected may become swollen and painful
the body's ______ line of defense is to react with a series of specific defenses called the immune response that is triggered by an antigen
a substance that triggers the immune response. it is located on the outside of a cell, and when it is unrecognized by the body, the cell is attacked.
a protein that recognizes and binds to a specific antigen
an injection of a weakened form of a pathogen to produce immunity
this virus can be spread through any form of sexual intercourse with an infected person or through contact with the blood or blood contact with an infected person

once oxygen is in your lungs, it moves from the air spaces in your lungs into the blood stream by this process. (high to low concentration)
red blood cells
in what cells in your blood is oxygen found?
oxygen moves from the red blood cells to the body cells by this process. (high to low concentration)
