EXSC 223 EXAM- Chapter 1 Questions
with Actual Answers 2026 Updated.
Anatomy - Answer studies the structure of body parts and their relationships to one another
Physiology - Answer the study of how the body and its parts work or function
gross anatomy (macroscopic anatomy) - Answer Study of structures that can be seen with
the naked eye
Regional Anatomy - Answer all the structures in a particular region of the body are examined
at the same time (ex: abdomen and leg)
systemic anatomy - Answer body structure is studied system by system
surface anatomy - Answer a. study of internal structures as they relate to the overlying skin
structures
Microscopic Anatomy - Answer deals with structures too small to be seen with the naked eye
Cystology - Answer examines cell structure and function
Histology - Answer the study of the microscopic structure of tissues
Developmental Anatomy - Answer traces structural changes that occur in the body
throughout the life span
Embryology - Answer a subdivision of developmental anatomy, concerns developmental
changes that occur before birth
Physiology - Answer focuses on events at the cellular or molecular level; body's abilities
depend on those of its individual cells and those abilities depend on the chemical reactions
principle of complementarity of structure and function - Answer Although it is possible to
study anatomy and physiology individually, they are really
inseparable because function always reflects structure. That is, what a structure can do
depends on its specific form. This concept is called the
, chemical level - Answer simplest level of the structural hierarchy; atoms combine to form
molecules; molecules associate to form organelles, which are basic components of cells
cellular level - Answer all cells share some common functions , but individual cells vary
widely in size and shape
single cells - Answer Simplest living creatures
tissue level - Answer groups of similar cells that have a common function
organ - Answer discrete structure composed of at least two tissue types (4 is more common)
that performs a specific function for the body
organ level - Answer extremely complex functions become possible
organ system level - Answer organs that work together to accomplish a common purpose
make up this system
organismal level - Answer highest level of structural organization is the organism (the living
human being); represents the sum total of all structural levels working together to keep us alive
requirements for life - Answer maintaining boundaries, movement, responsiveness,
digestion, metabolism, excretion, reproduction, growth
survival needs - Answer nutrients, oxygen, water, normal body temperature, appropriate
atmospheric pressure
Homeostasis - Answer the ability to maintain a relatively stable internal condition in an ever-
changing outside world; indicates a dynamic state of equilibrium, or a
balance, in which internal conditions vary, but always within
relatively narrow limits.
variable - Answer factor or event being regulated
3 components that regulate the variable - Answer receptor, control center, effector
