Defense System
This states that disease is caused by the presence of pathogenic microorganisms.
What is germ theory?
The stability of the internal environment and the mechanisms that maintain the stabiligy.
What is homeostasis?
Double Jeopardy: 600 Points
These cells activate macrophages and regulate the immune system. What are the two main types of these cells?
T Lymphocytes(T cells) , Helper T cells: alarms Killer t cells, Killer T cells: kills cells that go bad
Skin, hair, nails, mucous
What are some of your body's external defense (1st line of defense) systems?
proteins used by the immune system to neutralize pathogens
What are antibodies?
This chemist discovered fermentation and decay were caused by living microorganisms.
Who is Louis Pasteur?
This is the results of homeostasis function incorrectly.
What is disease?
How do natural killer cell
What are some ways humans/animals introduce diseases to their body?
Inflammation, defensive white blood cells, fever
What are some of the internal or 2nd line of defense systems?
This type of pathogen invades target cells and hijacks ribosomes for reproduction.
What are viruses?
These two phagocytes eat pathogens to get rid of them.
What are neutrophils and macrophages?
What are three mechanisms of innate immunity?
Physical barriers, like mucus
Antimicrobial proteins, like lysozymes and defensins
Signaling proteins, like interferons
Inflammation
Phagocytosis
White blood cells, like natural killer cells
What is the response time of the adaptive immune system after the initial infection?
What is greater than 96 hours?
This type of pathogen uses cells for food breaking down healthy tissue.
What are bacteria?
How do natural killer cells help fight infection?
These cells trigger apoptosis in your body's own infected cells?
What are the two mechanisms of adaptive immunity?
Humoral immunity (B cells, antibodies)
Cellular immunity (T cells)
This type of immunity can only be found in vertebrates.
What is adaptive immunity?
A student gets a large cut on their hand after cutting vegetables allowing bacteria to enter the blood stream. Name three defense mechanisms will occur during the first 48 hours?
Answers will vary.
Inflammation: alarms white blood cells
Fever: increases cell healing rate
Phagocytes ingest invading bacteria
What are the four causes of disease discussed in class?
What is presence of disease causing pathogens, hereditary factors, environmental factors, and gene mutations?
These cells mature in the bone marrow and produce antibodies in the body.
What is B lymphocyte (B cells)?
