Immune System Test Flashcards
To defend itself, the body must be able to:
Recognize it’s own tissues, ignore its own microflora, and eliminate abnormal cells
A protein marker on a cell is called an:
Antigen
What is a healthy bacteria that is found on the surface of your skin?
Microflora
Major Histocompatibility Complex
Allows body to recognize its own tissue, allows body to recognize foreign tissue, must be matches for tissue/organ transplants
The antibodies found in mother’s milk are an example of:
Naturall acquired passive immunity
Vaccinations are an example of:
Artificially acquired active immunity
Anti-venom injections are an example of:
Artificially acquired passive immunity
What is part of the first line of defence?
Skin, natural microflora, mucus
Which line of defence is specific?
Third line
Which line of defence do inflammation and fever all under?
Second line
Phagocytosis
Phagocytes detect foreign cells and engulf them in a small phagosome
Pain, redness, and swelling are usually a result of:
Inflammation
At what body temperature would death likely result?
44.4-45.5 degrees Celsius
Where is the temperature control centre of the brain?
Hypothalamus
The chill phase of a fever means body temperature is:
Increasing
What is released by the macrophage to increase body temperature?
Interleukin-1
What is released by the brain to increase body temperature?
Prostaglandins
What engulfs pathogens and presents them to T Cells?
Macrophage
The immune system reaction following an infection is turned off by?
Suppressor T Cells
A single memory B cell has room for the memory of:
One specific pathogen
When a B cell encounters a foreign pathogen, it divides rapidly and forms:
Plasma B Cells
The secretion of antibodies by B cells is part of:
Humoral immunity
Which T cell is responsible for killing pathogens?
Cytotoxic T Cells
What cell can attack pathogens that do not have antigens?
Natural killer cells
