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?

B.) There will be an absence of systole.
C.) The ventricles will not contract.

, 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.
Which of the following organs is responsible for the majority of the chemical digestion and absorption of

A.) Large intestine
B.) Small intestine
C.) Liver
D.) Pancreas - Answer-B.) Small intestine

A.) actin; myosin
B.) myosin; axon
C.) axon; actin
D.) dendrite; axon - Answer-A.) actin; myosin
Actin and myosin slide past each other, and the sarcomere unit shrinks.
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 initiating and short response on other body systems
D.) A slowly initiating but prolonged response on other body systems. - Answer-D.) A slowly initiating but
prolonged response on other body systems.
The endocrine system does not use ducts to deliver glandular products. Endocrine hormones produce a
slowly initiating response. However, the response is prolonged.
Which of the following terms refers to the middle layer of the skin that is made of connective tissue?
A.) Hypodermis
