, Epithelial - ANSWERSGlands are derived from what type of tissue?
Connective - ANSWERSThe cell types blood, bone, and fat, would be categorized into
which of the following major cell classes?
Interstitial fluid and plasma - ANSWERSExtracellular fluid is composed of
Homeostasis - ANSWERSThe maintenance of a stable internal environment compatible
for life is called
False - ANSWERSTrue/False? The primary mechanism to maintain homeostasis is
positive feedback
Cell - ANSWERSThe smallest functional unit in the human body, from a physiological
perspective is the
Cells, tissues, organs, organs systems, organism - ANSWERSWhat is the order of
complexity for the components of the body, from least to most complex?
Positive feedback - ANSWERSA 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 - ANSWERSStudy of functions of living things
Mechanisms (Why is a particular function being performed and how is it performed) -
ANSWERSPhysiology emphasizes
Anatomy - ANSWERSStudy of the structure of the body
Relatively stable - ANSWERSKept in a narrow range for optimal function
Examples of variables - ANSWERSBlood pressure, blood gas levels, blood glucose,
body ph, temperature
Sensor, integrating center, effector - ANSWERSThree components of reflex pathways
Negative feedback and positive feedback - ANSWERSReflex pathways can be
arranged to create 2 different types of feedback loops
Negative feedback - ANSWERSChange in a condition away from setpoint leads to a
response which counteracts that change
