ATI TEAS 7 Science Pretest Exam Questions
With Revised 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 - 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
, ©THEBRIGHTSTARS 2024
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.
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 - answer✔✔B.) Small intestine
The primary function of the small intestine is chemical digestion and absorption of nutrients.
Contraction occurs within 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
