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). - Correct Answers -
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
B.) Memory cells
Memory cells are a type of lymphocyte that responds more quickly to an antigen upon
reintroduction of the pathogen. - Correct Answers -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
C.) The ventricles will not contract.
, The Purkinje fiber impulse causes the contraction of the ventricles. - Correct Answers -
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.
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. - Correct Answers -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.
B.) Small intestine
The primary function of the small intestine is chemical digestion and absorption of
nutrients. - Correct Answers -Which of the following organs is responsible for the
majority of the chemical digestion and absorption of nutrients in the digestive system?
A.) Large intestine
B.) Small intestine
C.) Liver
D.) Pancreas
