| Topic 18-1 Infectious Disease |
| Objectives Explain the relationship between pathogens and infectious disease. List the kinds of pathogens that cause infectious diseases in humans. Identify four sources of pathogens. |
| State Goals |
Classwork-Homework
On the BoardPathogen: any agent that causes disease Infectious Disease: disease caused by the presence of a living thing within the body Toxin:poison White Blood Cell: cell that protects the body against disease Antigen: signal molecule that produces an immune response Antibody: molecule the body makes to protect itself from disease Contagious: can be spread from one person to another

| Topic 18-2 The Body's Defenses | ||||||||||||||||
| Objectives Explain how the body's first line of defense guards against pathogens. Describe what happens during the inflammatory response. State how the immune system responds to pathogens. Identify how HIV affects the immune system and how it spreads. |

| Classwork-Homework
On the Board Inflammatory Response: body's second line of defense against pathogens Phagocyte: white blood cell that eats pathogens Immune Response: body's third line of defense against pathogens Lymphocyte: white blood cells that distinguish different kinds of pathogens T Cell: identify pathogens and distinguish one kind from another Antigen: B Cell:produce proteins that help destroy pathogens Antibody: proteins that help destroy pathogens AIDS: acquired immune deficiency syndrome HIV: human immunodeficiency virus Body's Defenses Against Disease

| State Goals | ||||||||
| Classwork-Homework
On the Board Immunity: resistance to a specific disease Active Immunity: body has developed antibodies against a disease (chicken pox) Vaccination: Vaccine: Antibiotic: chemical made by a living organism that kills bacteria Acquired Immunity: immunity that people develop, or acquire during their lives Passive Immunity: Antibodies are obtained from somewhere else (injection) Natural Immunity: an immunity people are born with Diseases and Vaccines

| Objectives Learn the concepts involved in epidemology. Trace the spread of a pathogen through a population. |
| State Goals 11.A.2d Use data to produce reasonable explanations. 13.B.3c Describe how occupations use scientific and technological knowledge and skills. |
| Classwork-Homework
On the Board Epidemic: more cases of a particular disease than expected Pathogen: any agent that causes disease Infectous agents: things that cause disease Transmission: how a disease is spread Epidemology: study of epidemics Prevention: stopping the spread of a disease Outbreak! Investigating

| Topic 18-4 Noninfectious Disease |
| Objectives Identify the causes of allergies. Explain how diabetes affects the body. Describe the effects of cancer on the body. Identify causes of cancer. |
| State Goals |
| Classwork-Homework
On the Board Noninfectious Disease: diseases not caused by pathogens Allergy: immune system is sensitive to a foreign substance Allergen: a substance that causes an allergy Histamine: chemical that is responsible for the symptoms of an allergy Asthma: a disorder where the reparatory passages narrow significantly Insulin: enables body cells to take in glucose from the blood and use as energy Diabetes: pancreas fails to produce enough insulin or the body cells fail to use insulin properly Tumor: mass or lump of cells Carcinogen: substances or factors that can cause cancer Benign Tumor: mass of cells that is usually harmless Malignant Tumor: harmful mass of cells that can spread throughout the body

| Levels of Organization In unicellular (single-celled)
organisms, the single cell performs all life functions. It functions independently.
However, multicellular (many celled) organisms have various levels of organization within
them. Individual cells may perform specific functions (causing a division of labor) and
work together for the good of the entire organism. The cells become dependent on one
another. Explore Cells, Tissues, Organs, Organ Systems, and Organisms. |

| Anthrax
Anthrax is an acute infectious disease caused by the spore-forming bacterium Bacillus
anthracis. |
