HUMAN PHYSIOLOGY FROM CELLS TO
SYSTEMS 20TH EDITION ACTUAL TEST PAPER
QUESTIONS AND SOLUTIONS GRADED A+
◉ Connective.
Answer: The cell types blood, bone, and fat, would be categorized
into which of the following major cell classes?
◉ Interstitial fluid and plasma.
Answer: Extracellular fluid is composed of
◉ Homeostasis.
Answer: The maintenance of a stable internal environment
compatible for life is called
◉ False.
Answer: True/False? The primary mechanism to maintain
homeostasis is positive feedback
◉ Cell.
Answer: The smallest functional unit in the human body, from a
physiological perspective is the
,◉ Cells, tissues, organs, organs systems, organism.
Answer: What is the order of complexity for the components of the
body, from least to most complex?
◉ Positive feedback.
Answer: A virus enters the body, and it activates immune cells. These
immune cells release chemical messengers that activate more
immune cells. This type of response would be characterized as
◉ Physiology.
Answer: Study of functions of living things
◉ Mechanisms (Why is a particular function being performed and
how is it performed).
Answer: Physiology emphasizes
◉ Anatomy.
Answer: Study of the structure of the body
◉ Relatively stable.
Answer: Kept in a narrow range for optimal function
,◉ Examples of variables.
Answer: Blood pressure, blood gas levels, blood glucose, body ph,
temperature
◉ Sensor, integrating center, effector.
Answer: Three components of reflex pathways
◉ Negative feedback and positive feedback.
Answer: Reflex pathways can be arranged to create 2 different types
of feedback loops
◉ Negative feedback.
Answer: Change in a condition away from setpoint leads to a
response which counteracts that change
◉ Positive feedback.
Answer: Change in a condition away from setpoint leads to a
response which amplifies that change
◉ Antagonistic effectors.
Answer: Homeostasis is often maintained by opposing effectors that
move conditions in opposite directions
, ◉ Intrinsically (local response).
Answer: Cells within the organ sense a change and signal to
neighboring cells to respond appropriately
◉ Extrinsically (global response).
Answer: Outside of the organ (examples - endocrine and nervous
system)
◉ Cell.
Answer: Basic unit of structure and function of living things
◉ Tissue.
Answer: Group of similar cells that perform a similar function
◉ Organ.
Answer: Group of two or more tissues
◉ Organ system.
Answer: Group of organs that work together to perform related
functions
◉ Organism.
