Vaccine-Preventable Diseases
Influenza is a virus that can be easily spread from person to
person and kills thousands of people each year. Healthcare workers
are at risk of exposing themselves to infectious diseases from
patients and material and therefore can also potentially transmit
these diseases to others. Preventing and controlling the spread of
vaccine preventable diseases in the health care setting is vital to
ensure proper infection control practices should an outbreak occur.
As such, the Centers for Disease...

b. juxtaglomerular cells
c. hepatic cells
d. none of the above
2. JG cells are located in which of the following locations?
a. DCT
b. efferent arterioles
c. afferent arterioles
d. proximal tubules
3. When blood pressure decreases
a. renin release is decreased
b. renin release is increased
c. ACE activity is decreased
d. none of the above
4. When angiotensin II increases, the radius of the efferent
arteriole

A virus such as influenza is only one type of pathogen that can
invade the human body and cause disease. Different pathogens
interact with different components of the immune system in
different ways.
(a) Describe the role of skin and mucosae as surface barriers
and the mechanisms that enable these anatomical structures to
prevent infections.
(b) Discuss three examples of how the lymphatic and immune
systems work together both structurally and functionally to fight
infections such as influenza.
TH cells can recognize and respond to antigens from
both extracellular and intracellular pathogens
True
False
Complement activation is directed against microbial pathogens.
Which of the following describe the specific functions of the MBL
protein in complement activation
Punctures cell walls and plasma membranes causing osmotic
lysis
Induces vasodilation and increases vascular permeability
Promotes diapedesis of white blood cells
Decreases ribosome function during viral infection
Recognition of a microbial PAMP
Phagocytosis leads to the destruction of pathogens at the site...

problems in functional ability? (2 points)
43. The Memory Cells are a type of WBC, White Blood

through: a) facilitated transport, b) active transport, c)
pinocytosis. d) transport through the cell membrane by a process
termed exocytosis, e) all are true.
