QUESTIONS AND ANSWERS 2022
Inflammation, production of interferons, 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
ANS: C.
If the internal barrier is breached, the second line of defense is the internal aspect of the innate
immune system, a collection of non specific cellular responses (inflammation, production of
interferons, ingestion of pathogens by phagocytes)
What feature of the adaptive immune system decreased 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
ANS: B.
Memory cells are a type of lymphocytes 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 at the sinoartrial node never
reaches the Purkinje 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
ANS: C.
The ventricles will not contract
Which if the following results from the blockage of blood flow to cardiac muscle tissue?
A. Myocardial infarction
B. Atherosclerosis
C. Embolus
D. Stroke
ANS: A.
, Myocardial infarction (a heart attack) occurs when cardia muscles dies ads a result of blood flow
Which of the following describes the ink between damaged villi and malnutrition?
A. Damaged villi decrease the nutrient-absorbing surface area in the GI tract
B. If villi are damaged, the surface area of the stomach is decreased
C. Peristalis of the large intestine will be diminished
D. Damaged villi cause gastric reflux disease
ANS: A.
damaged villi decrease the nutrient-absorbing surface area in the gastrointestinal tract
Which of the following organs is responsible for the majority of the chemical digestion and absorption
of nutrient in the digestive system?
A. Large intestines
B. Small intestines
C. Liver
D. Pancreas
ANS: B
The primary function of the small intestine is chemical ingestion and absorption of nutrients.
Contraction occurs when the thin ___ filaments slide past the thicker ___ filaments, causing the
sarcomere unit to shorten or contract
A. actin; myosin
B. myosin; axon
C. axon; actin
D. dendrite; axon
ANS: A.
actin and myosin slide past each other, and the sarcomere unit shrinks
Which of the following nerve structures transmits nerve impulses to other cells?
A. axon
B. Dendrite
C. Cell body
D. Glial Cells
ANS: A.
The axon transmits signals to other cells.
The endocrine system is a collection of ductless glands that produce which of the following
responses?
A. a quickly initiating but prolonged response on other body systems
B. a slowly initiating and short response on other body systems
C. a quickly inititaintng and short response on other body systems
