| 399468586 | Infectious diseases | disease caused by a microorganism that disrupts normal body functions | |
| 399468587 | germ theory of disease | idea that infectious diseases are casued by microorganisms | |
| 399468588 | What can infectious diseases be caused by? | viruses , bacteria , fungi , "protists" , and parasites | |
| 399468589 | Koch's Postulates | set of guidlines developed by Koch thathelps identify the mircroorganism that causes a specific disease | |
| 399468590 | Virus | nonliving , replicate by inserting their genetic material into a host cell and taking over many of the host cell's functions. Diseases caused common cold , influenza, chickenpox, and warts | |
| 399468591 | Bacteria | Break down the tissues of an infected organism for food , or realease toxins that interfere with normal activity in the host. Caused cy strptoccus infetion , diptheria , botulism, and anthrax | |
| 399468592 | fungi | cause infections on the surface of the skin , mouth ,throat , fingernails, and toenails ; dangerous infections may spreas to lungs or other orgnaisms. Caused ringworm and thrush. | |
| 399468593 | "protists" | Single-celled eukaryotes may infect people through contaimated water and insect bites; they take nutrients from their hosts; most inflic damage to cells and tissues, Diseased caused malaria , african sleeping sickness, and intestinal diseases. | |
| 399468594 | parastic worms | Most parasites that infect humans are wormlike; may enter through the mouth, nose, anus, or skin; most reside in the intestinal tract where they absorb nutrients from the host. Disease caused trichinsis , schistosomiasis , hookworm, elephantiasis | |
| 399468595 | How do diseases spread? | through coughing , sneexing , physical contact, infeced animals , or body fluids. Also by contaminated food and water. | |
| 399468596 | zoonosis | any diseas that can be transmitted from animals to humans | |
| 399468597 | vectors | transport the pathogen but usually do not get sick themselves | |
| 399468598 | inflammatory response | causes an infected areas to become red and painful, or inflamed | |
| 399468599 | What are some nonspecific defences include? | skin, tears, and other secretions,the inflammatory response , interferons, and fever | |
| 399468600 | histamines | increase the flow of blood and fluids to the affected area | |
| 399468601 | interferons | one of a group of proteins that helps cells resist viral infections | |
| 399468602 | fever | increased body temperature that occurs in responses to infection | |
| 399468603 | immune response | the body's specific recognition, response, and memory to a pathogen attack | |
| 399468604 | antigen | any foreign substance that can stimulate an immune response | |
| 399468605 | antibodies | protein that either attacks antagens directly or produces antigen-binding proteins | |
| 399468606 | hummoral immunity | immunity against antigens in body fluids, such as a blood and a lymph | |
| 399468607 | plasma cells | produce and release antibodies that are carried through the blood stream | |
| 399468608 | memory b cells | react quickly if the same pathagon enters the body--- recognize a particulare antigen remain alive | |
| 399468609 | cell-mediated immunity | immune response that defends the body ahainst viruses, fungi , and abnormal cancer cells inside living things | |
| 399468610 | vaccination | injection of a weakened form of a pathogen , or a similar or less dangerous pathogen, to proice immunity | |
| 399468611 | active immunity | vaccination stimulates the immune system with an antigen. The immune system produces memory B cells and memory T cells that quicken and strengthen the body's response to repeated infection. | |
| 399468612 | passive immunity | antibodies produce against a pathogen by other individuals or animals can be used to produce temporary immunity | |
| 399468613 | What do public health measures help? | prevent dieses by monitoring and regulating food and water supplies, promotiong vaccination, and promoting behaviors that avoid infection. | |
| 399468614 | What do antibiotics do so and antiviral medications? | Can kill bacteria and can slow down viral activity | |
| 399468615 | What are two major reasons for the emergence of new diseases? | ongoing merging of human and animal habitats and the increases in the ecotic animal trade |
