ATI TEAS 7 Science Pretest
Inflammation, production of interferon, and ingestion of pathogens by phagocytes
are nonspecific cellular responses by which of the following?
A.) The internal aspect of adaptive immune system
B.) Antibody-mediated immunity
C.) The internal aspect of the innate immune system
D.) Passive immunity - ANSWER C.) The internal aspect of
the innate immune system
If the external barrier is breached, the second line of defense is the internal aspect
of the innate immune system, a collection of nonspecific cellular responses
(inflammation, production of interferon, ingestion of pathogens by phagocytes).
,What feature of the adaptive immune system decreases the amount of time it
takes for the body to respond to a particular antigen?
A.) Unbroken skin
B.) Memory Cells
C.) Cytotoxic T-cells
D.) Inflammation - ANSWER B.) Memory cells
Memory cells are a type of lymphocyte that responds more quickly to an antigen
upon reintroduction of the pathogen.
Which of the following occurs in the cardiac cycle if the impulse triggered a at the
sinoatrial mode never reaches the Purkinje fibers of the heart?
A.) The atria will not contract.
B.) There will be an absence of systole.
C.) The ventricles will not contract.
, D.) Diastole will shorten in duration. - ANSWER C.) The
ventricles will not contract.
The Purkinje fiber impulse causes the contraction of the ventricles.
Which of the following describes the link between damages villi and malnutrition?
A.) Damaged villi decrease the nutrient-absorbing surface area in the
gastrointestinal tract.
B.) If villi are damaged, the surface area of the stomach is decreased.
C.)Peristalsis of the large intestine will be diminished.
D.) Damaged villi cause gastric reflux disease. - ANSWER A.)
Damaged villi decrease the nutrient-absorbing surface area in the gastrointestinal
tract.
Villi of the small intestine provide a greater nutrient-absorbing surface area in the
gastrointestinal tract.
