Total questions: 12
Worksheet time: 7mins
Which of the following is an example of a physical barrier that stops pathogens from entering the body?
Skin and epithelial cells
Ear wax
Mucus
Acid
What is the role of histamine in the inflammatory response?
It engulfs pathogens.
It releases cytokines.
It causes vasodilation and increased permeability of capillaries.
It digests pathogens.
what are the white blood cells which release histamine called
helper cells
phagocytes
pathogens
mast cells
what is a disease causing cell called
phagocytes
cytokines
pathogens
mast cells
histamine causes
increased blood flow
cytokines to be released
pathogens to be destroyed
phagocytosis
Which of the following are chemical secretions produced against invading pathogens?
Name the closely-packed cells found in the skin and inner linings of the digestive and respiratory systems.
(a)
vasodilation is when
the capillary gets bigger to increase blood flow
the artery gets wider to increase blood flow.
increased blood flow through capillary
the muscles in the walls of the artery contract
Which of the following is not part of the inflammatory response?
phagocytosis
vasodilation
increased capillary permeability
antibodies
During the inflammatory response, the production of histamine immediately results in;
vasodilation & increased capillary permeability
production of cytokines
phagocytosis of pathogens
accumulation of phagocytes
The following steps occur during the inflammatory response:
1. Blood flow increases.
2. Histamine is released by mast cells.
3. Phagocytes accumulate at the site of infection.
4. Vasodilation occurs and capillary permeability increases.
In which sequence do these steps occur?
2, 1, 4, 3
4, 2, 1, 3
4, 1, 3, 2
2, 4, 1, 3
Cytokines act at the site of infection by
signalling the production of phagocytes
stimulating phagocytes to release antibodies
carrying out phagocytosis to engulf bacteria
causing the accumulation of phagocytes.
