What is the difference between infectious and noninfectious diseases?

• Infectious diseases are caused by pathogens and cannot be transmitted.

• Noninfectious diseases are caused by pathogens and can be transmitted.

• Infectious diseases are caused by genetics and can be transmitted.

• Infectious diseases are caused by pathogens and can be transmitted, while noninfectious diseases are not caused by pathogens and cannot be transmitted.

What are pathogens?

• The immune system is a group of muscles that protect the body from harm.

• The immune system is a collection of organs that help with digestion.

What is the function of antibodies in the immune system?

• The function of antibodies in the immune system is to attack healthy cells.

• The function of antibodies in the immune system is to produce antigens.

• The function of antibodies in the immune system is to identify and neutralize antigens.
