Exam 1 A&P Theory Galen
What is regional anatomy? - ANSWER-Study of interrelationships of all the structures in
a specific body region EX. abdomen
What is systemic anatomy? - ANSWER-The study of the structures that make up a
discrete body system
What is homeostasis? - ANSWER-The state of steady internal conditions maintained by
living things
What are the six levels of structural organization? - ANSWER-chemical, cellular, tissue,
organ, organ system, organismal
What is the chemical level? - ANSWER-atoms combine to form molecules
What is human anatomy? - ANSWER-Scientific study of the bodies structures
What is gross anatomy? - ANSWER-Study of structures that can be seen with the
naked eye
What is microscopic anatomy? - ANSWER-the study of structures that are too small to
be seen with the naked eye
What does microscopic anatomy include? - ANSWER-Cytology = the study of cells and
histology = the study of tissues
What is the cellular level? - ANSWER-A variety of molecules combine to form the fluid
and organelles of a body cell
What is the tissue level? - ANSWER-A community of similar cells form a body tissue
What is the organ level? - ANSWER-Two or more different tissues combine to form an
organ
What is the organ system level? - ANSWER-Organ systems consist of different organs
that work together closely to perform the functions of a body system
What is the organism level? - ANSWER-Many organ systems work harmoniously
together to perform the functions of an independent organism
What is the bodies largest organ system? - ANSWER-The integumentary system
, What is metabolism? - ANSWER-The sun of all anabolic and catabolic reactions that
take place in the body, both anabolism and catabolism occur simultaneously and
continuously to keep you ALIVE
What is developmental anatomy? - ANSWER-The changes the body goes through in
life. Which includes differentiation in which i specialized cells become specialized in
structure and function to perform certain tasks in the body
What is growth? - ANSWER-Increase in body size
What is reproduction? - ANSWER-Formation of new organisms from parent organisms
When is brain damage likely without oxygen? - ANSWER-4-7 minutes
What is a nutrient? - ANSWER-A substance in foods and beverages that is essential to
human survival ( three basic classes, water, nutrients & micronutrients )
Narrow range of temperature - ANSWER-normal body temp is 98.6 which is needed for
many cellular processes ex when you sweat your body is cooling down
What is a response to cold? - ANSWER-Shivering, attempting to generate heat
Narrow range of atmospheric pressure - ANSWER-needed for proper gas exchange of
O2 and CO2 in the lungs
Homeostasis - ANSWER-process by which organisms maintain a relatively stable
internal environment
What is negative feedback? - ANSWER-Body REVERSES an original stimulus to regain
balance ex sweating
What are the three negative feedback components? - ANSWER-Sensor; monitors a
physiological value
Control center; the component in a feedback system that compares the value to the
normal range
Effector; the component in a feedback system that causes a change to reverse the
situation and return the value to the normal range
What is positive feedback? - ANSWER-Body ENHANCES original stimulus to make
deviation greater
What is an example of positive feedback? - ANSWER-Blood clotting. The initial clotting
triggers the formation of more clots. Childbirth. Nerve signals.
