Communicable Disease
Communicable Disease Key Terms
| Question | Answer |
|---|---|
| What is a Communicable Disease? | A disease that can be Transmitted from one living thing to another or through the environment. |
| What is a Pathogen? | An organism that causes disease. |
| What is an Infection? | A condition that occurs when pathogens enter the body, multiply and damage body cells. |
| What is a Virus? | Pieces of genetic materials surrounded by a protein coat. |
| What is the life cycle of viruses? | Virus goes in body, penetrates host cell, takes control of cell to manufacture more viruses, new viruses burst from cell, new viruses take over other cells. |
| What is a Bacteria? | Single Celled Microorganisms. |
| What is a Toxin? | A substance that kills cells or interferes with their functions. |
| Examples of Viruses? | Common Cold, Flu, Polio, Measles, Herpes, Rabies, small pox. |
| Examples of Bacteria? | Strep throat, tuberculosis, Bacterial pink eye, lyme disease. |
| Examples of Fungi? | Athletes foots, ringworm, vaginal yeast infection. |
| Examples of Protozoans? | malaria, amoebic dysentery, sleeping sickness |
| Examples of Rickettsias? | typhus, rocky mountain spotted fever |
| What is a Fungi? | Plant like organisms such as mold or yeast some types can cause disease of the skin, mucous membranes, or the lung. |
| What is a Protozoans? | Singe celled organisms that are larger and more complex then bacteria, that can cause disease with people with weaker immune system. |
| What is a Rickettsias? | Pathogens that resemble bacteria they multiply by invading the cells of another life form, often they entire the human through the bite of insects such as fleas and lice. |
| What are the 3 ways Communicable diseases are transmitted? | Direct Contact, Indirect Contact, and Airborne Transmission. |
| What is Direct Contact? | Through touching, biting, kissing, sexual contact, sneezing, coughing. |
| What are the 3 ways of indirect Contact? | Contaminated Objects, vectors, and Water and food. |
| What is Indirect Contact? | A from of transmission which can infect without being close to an infected person. |
| What are contaminated objects? | Inanimate objects that are contaminated with infectious discharges or secretions. |
| What is water and food; in terms of communicable diseases? | Major source of contamination and illness because of careless handling and storage of food. |
| What are vectors? | An organism, usually an arthropod(tick) that caries and transmits pathogens to humans or other animals. |
| What is Airborne Transmission? | Pathogens from a sneeze or a cough may be in air and travel long distances. |
| What are the 5 ways you can reduce your risk of getting a communicable disease? | Washing hands, handling food properly, avoid unnecessary contact with sick people, restrain sexual activity, manage stress. |
| What is the immune system? | Network of cells, tissues, organs, chemicals that fight off pathogens |
| What are the 5 physical and chemical barriers? | Skin, Tears and Saliva, Mucous membranes, Cilia, and Gastric Juice. |
| Explain how this prevent communicable diseases: Skin? | Few Pathogens can pass through tough layer of dead skin cells that surround body. |
| Explain how this prevent communicable diseases: Tears and Saliva? | Contains enzymes that destroy or disable many pathogens. |
| Explain how this prevent communicable diseases: Mucous Membranes? | Mucus carries trapped pathogen to other areas of the body for disposal. |
| Explain how this prevent communicable diseases: Cilia? | Sweep mucus and pathogens to the throat where they can be swallowed or coughed out. |
| Explain how this prevent communicable diseases: Gastric Juice? | Destroys many pathogens than enter the body through the nose and mouth in stomach. |
| Describe how the inflammatory response works? | Prevents further tissue injury and halts invading pathogens. |
| Describe how Phagcyte work as a defense stragies? | A white blood cell that attacks pathogens. |
| What is Antigen? | A substance that is capable of triggering an immune response. |
| What is Immunity? | The state of being protected against a particular disease. |
| What is Lymphocytes? | A specialized white blood cell that coordinates and performs many of the functions of specific community. |
| What is Helper T cells? | Triggers the production of B cells and Killer T cells. |
| What is Killer T cells? | Attack and destroy infected body cells. |
| What is Suppressor T cells? | Coordinate the activities of other T cells, suppress helper T cells when the infection is clear. |
| What is Antibody? | A protein that acts against a specific antigen. |
| What is Active Immunity? | Immunity in you body that develops to protect you from diseases. |
| What is Vaccine? | A preparation of dead or weakened pathogens that are introduced into the body to stimulate an immune response. |
| What is Passive Immunity? | Receiving antibodies from another person or an animal. |
