Cell Types
100
An organism, a virus or a protein that causes disease
What is a pathogen?
100
The ability to resist or recover from a disease.
What is immunity?
100

This states that disease is caused by the presence of pathogenic microorganisms.

What is germ theory?

100

The stability of the internal environment and the mechanisms that maintain the stabiligy.

What is homeostasis?

100

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

200

Skin, hair, nails, mucous

What are some of your body's external defense (1st line of defense) systems?

200

proteins used by the immune system to neutralize pathogens

What are antibodies?

200

This chemist discovered fermentation and decay were caused by living microorganisms.

Who is Louis Pasteur?

200

This is the results of homeostasis function incorrectly.

What is disease?

200

How do natural killer cell

What are some ways humans/animals introduce diseases to their body?

300

Inflammation, defensive white blood cells, fever

What are some of the internal or 2nd line of defense systems?

300
Once your body has fought a pathogen; it has T and B cells that remember it.
What are memory cells?
300

This type of pathogen invades target cells and hijacks ribosomes for reproduction.

What are viruses?

300

These two phagocytes eat pathogens to get rid of them.

What are neutrophils and macrophages?

400

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

400
A substance made from weakened or killed pathogens introduced into the body to produce immunity.
What is a vaccine?
400

What is the response time of the adaptive immune system after the initial infection?

What is greater than 96 hours?

400

This type of pathogen uses cells for food breaking down healthy tissue. 

What are bacteria?

400

How do natural killer cells help fight infection?

These cells trigger apoptosis in your body's own infected cells?

500

What are the two mechanisms of adaptive immunity?

Humoral immunity (B cells, antibodies)

Cellular immunity (T cells)

500

This type of immunity can only be found in vertebrates.

What is adaptive immunity?

500

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

500

What are the four causes of disease discussed in class?

What is presence of disease causing pathogens, hereditary factors, environmental factors, and gene mutations?

500

These cells mature in the bone marrow and produce antibodies in the body.

What is B lymphocyte (B cells)?
