The Hierarchy of Complexity - ANSWER-Organ system-organs-tissues-cells-organelles-
molecules-atoms
situs invertus - ANSWER-heart is on the opposite side
Organization - ANSWER-living things exhibit a higher level of organization than
nonliving things
Cellular Composition - ANSWER-living matter is always compartmentalized into one or
more cells
Metabolism - ANSWER-internal chemical reactions; the sum of all biochemical events
that occur in the body
Responsiveness - ANSWER-ability to sense and react to stimuli (irritability or
excitability)
Movement - ANSWER-of organism and/or of substances within the organism
Characteristics of life - ANSWER-organization, cellular composition, metabolism,
responsiveness and movement, homeostasis, development, reproduction, evolution
Homeostasis - ANSWER-the ability to detect change, activate mechanisms that oppose
it and thereby maintain stable internal conditions
Physiological Variation - ANSWER-Sex, age, diet, weight, physical activity, genetics and
environment
Feedback Loops - ANSWER-biological mechanisms where homeostasis is maintained
Homeostasis in Body Temperature - ANSWER--If too warm, vessels dilate in the skin
and sweating begins (heat-losing mechanism)
-If too cold, vessels in the skin constrict and shivering begins (heat-gaining mechanism)

Integrating (control) Center - ANSWER-control center that processes the sensory
information, "makes a decision," and directs the response
Effector - ANSWER-cell or organ that carries out the final corrective action to restore
homeostasis
Positive Feedback - ANSWER-Self-amplifying cycle where the feedback loop is
repeated. Normal way of producing rapid changes. Can sometimes be dangerous. ex.
childbirth
Gradient - ANSWER-a difference in chemical concentration, charge, temperature, or
pressure between two points. Chemicals flow down concentration gradients. Charged
particles flow down electrical gradients. Heat flows down thermal gradients.
CT Scan - ANSWER-computed tomography scan
MRI - ANSWER-magnetic resonance imaging
PET scan - ANSWER-a visual display of brain activity that detects where a radioactive
form of glucose goes while the brain performs a given task
Sonography - ANSWER-high frequency sound waves echo back from internal organs
The relationship between function and structure - ANSWER-Form creates function,
function predicts form
The primary function of red blood cells - ANSWER-To transport vital gases to and from
the body tissues. Red blood cells transport oxygen to the tissues and carbon dioxide
from the tissues to the lungs so that it can be exhaled out of the body.
How are red blood cells unlike other body cells? - ANSWER-As they mature they lose
their nucleus and organelles, which allows room for more hemoglobin molecules which
are oxygen binding proteins.
What do red blood cells display? - ANSWER-Viscoelasticity, they have the ability to go
back to their original shape if they become deformed due to stress. This allows them to
be able to flow through narrow blood vessels.
Superior - ANSWER-Structure that is toward the head of the body
How many body cavities are in the body? - ANSWER-4
Ventral/Dorsal - ANSWER-front and back
