Disease
I will classify diseases as infectious and
noninfectious. My goal is_____________.
noninfectious disease a disease that is not contagious
chronic lasting for a long time
Chapter 14 Review
allergy an abnormal reaction to a foreign substance
immune response the steps taken by the immune system when invaded by pathogens
immunity the ability to protect against pathogens before getting sick
lymph nodes areas that filter lymph and trap pathogens
genetic disorder a noncontagious disease that is usually inherited
allergen something that causes an allergy
virus a nonliving microscopic particle that often causes disease
acute beginning suddenly and lasting for a short time
infectious disease a disease that is contagious and is caused by a pathogen
lymphatic system part of the immune system and helps fight pathogens
Three ways that infectious and noninfectious diseases are alike are both are abnormal conditions causing illness, both
produce symptoms , and both can be either acute or chronic
Eight components of the immune and lymphatic systems are lymph nodes, lymphatic vessels, thymus, tonsils,
adenoids, appendix, bone marrow, and spleen

List three ways that infectious and noninfectious diseases are alike
List eight components of the immune and lymphatic systems.
Pathogens
•
pathogen- an organism or particle that causes disease
•
infectious disease- contagious disease caused by pathogens
•
noninfectious disease- a disease caused by pathogens and is not contagious
•
Four common groups of pathogens are bacteria, viruses, fungi, and protists
Infectious Diseases
•
acute-suddenly and lastly for a short time
•
chronic- for a long time and/or reoccurring frequently
•
virus-nonliving particle that can infect cells and cause disease
•
Bacteria are masters of change
•
Viruses are about 300 times smaller than cells
Noninfectious Diseases
• genetic disorder-an abnormal condition that is usually inherited
through genes
• allergy-an abnormal reaction to a foreign substance
• allergen-substance that provokes allergies
• Noninfectious diseases are either acute(stroke) or chronic
(diabetes or cancer)
• The three ways that infectious and noninfectious diseases are alike
are they both are abdominal conditions causing illness, both
produce symptoms, and both can be either acute or chronic
The Immune System
• lymphatic system-a major component of he immune system that
protects the body from pathogens
• lymph node- a rounded mass of tissues that filters fluids from other
body tissues and traps pathogens’
• immune response-the series of reactions that take place when
white blood cells fight against infection.
• Components in the immune system are the thymus, spleen, and
tonsils
• All white blood cells are first produced in the bone marrow
• The eight components of the immune and lymphatic system are
lymph nodes, lymphatic vessels, thymus, tonsils, adenoids,
appendix, bone marrow, and spleen
Immunity
• Immunity-the body’s ability to protect itself from pathogens before
they cause disease
• active immunity-a type of immunity in which the immune system
produces antibodies in response to the presence of a pathogen
• Your body acquires active immunity in two ways. One is by getting
the disease first. The other is from vaccinations
