BIOL 251- ANATOMY AND
PHYSIOLOGY EXAM 1 WITH 100%
CORRECT ANSWERS 2025/2026
Anatomy correct answers >> the various structures of the
body, what they look like, and their relationship to one another
Gross Anatomy correct answers >> structures visible to the
naked eye
Regional Anatomy correct answers >> specific regions of the
body such as the head or chest
can find organs from different systems in the same region
systemic anatomy correct answers >> studies the anatomy
of each functional body system
systems span across multiple regions
Microscopic Anatomy correct answers >> deals with
structures too small to be seen with the naked eye
Cytology correct answers >> study of cells
Histology correct answers >> study of tissues
,2|Page
physiology correct answers >> how these individual body
parts work (or function) on a normal level
principle of complementarity of structure and function correct
answers >> what a structure can do is dependent on its form
bones are hard and hold up most of our body weight
chemical level of organization correct answers >> atoms and
molecules
cellular level of organization correct answers >> smallest
living unit of the body
cells function differently depending on where they are found
tissue level of organization correct answers >> collections of
2 or more cells that carry out a similar function
Four Basic Types of Tissue correct answers >> epithelial,
connective, muscle, nervous
organ correct answers >> any structure with two or more
tissue types
Organ level of organization correct answers >> tissues
operate together to perform a certain function
,3|Page
Organ System Level of organiztion correct answers >>
multiple organs work together to accomplish a purpose
Organismal Level of Organization correct answers >> All
organ systems working together to keep the organism alive
Necessary Life Function #1 - Maintaining Boundaries correct
answers >> cell level --> cell membranes keep organelles
together and separate intercellular and extracellular fluid
organismal level --> skin holds us together, prevents water loss,
and helps prevent the entrance of pathogens
Necessary Life Function #2- Movement correct answers >>
Cooperation of skeletal and muscular systems to coordinate
actions
Necessary Life Function #3- Responsiveness (or Excitability)
correct answers >> Sensing environmental changes and
responding to them
Are all cells responsive? correct answers >> yes to a certain
extent, but CNS cells are the most responsive
Necessary Life Function #4- Digestion correct answers >>
Food is broken down to simple molecules to be absorbed to blood
and delivered to various tissues
, 4|Page
Necessary Life Function #5- Metabolism correct answers >>
Catabolism, Anabolism, and Cellular Respiration
Catabolism correct answers >> breaking down
anabolism correct answers >> building up
cellular respiration correct answers >> ATP Production
through glucose and oxygen
Necessary Life Function #6- Excretion correct answers >>
Removal of Waste produced during digestive and metabolic
functions
ex- Digestive waste, urine, respiratory release of CO2
Necessary Life Function #7- Reproduction correct answers >>
Cell Level --> cells must divide for organism to survive
Organismal level --> Production of offspring
Necessary Life Function #8- Growth correct answers >>
Increase in the number of body cells, or increase in size of
individual cells themselves
anabolic rate must be greater than catabolic rate
