ECPI Anatomy Physiology Exam
Questions and Answers Latest Update
Origins of Medical science - Answer-1.) Started with superstition and magic
2.) Originated in Greek & Latin terminology

Scientific Method - Answer-"Investigating the Natural World"

Testing a Hypothesis = - Answer-1.) Rejecting or Accepting the hypothesis
2.) Based on results of experiment and observations

Anatomy + Physiology = ? - Answer-How the body maintains life

Anatomy - Answer-"cutting up"
1. structures of the body
2. Forms/ organization

Physiology - Answer-"relationship to nature"
1. functions of the body
2. What do they do and how?

Gene Expression Profiling - Answer-Reveals commonalities among pairs of diseases
that had not been suspected based on whole-body-level observations

Chemical Organization - Answer-1.Atoms
2. Molecules

Subatomic Particles - Answer-Make up atoms

Molecules - Answer-Where atoms join together

Macromolecules - Answer-Small molecules join together to make larger molecules

Human Organism Organization smallest-largest - Answer-1. Subatomc particles
2. atoms
3. molecules
4. macromolecules
5. organelles
6. cells
7. tissues
8. organs
9. organ systems
10. organisms

,Cells - Answer-basic unit

Organelles - Answer-carry on specific activities
e. proteins, carbohydrates, lipids, nucleic acids

tissues - Answer-layers/masses of cells with special functions

Organs - Answer-groups of tissues with specific functions

organs systems - Answer-groups of organs that function close together

organisms - Answer-interacting organ systems

Internal environment - Answer-environment within the body in which the cells live

Cell membrane - Answer-interior and exterior cell membranes

Interior cell membrane - Answer-intracellular fluid

exterior cell membrane - Answer-extracellular fluid

homeostasis - Answer-the maintenance of a relatively constant internal environment

Interdependency of cells - Answer--cells depend on one another
-if some cells arent able to function, other cells and the entire organism may suffer
-structure and function are interrelated

Gradients & Permeability - Answer-down a gradient (High to Low)
high pressure to low pressure
high concentration to low concentration

Diffusion - Answer-high concentration to low concentration (concentration gradient)

membrane permeability - Answer-what is allowed in to the membrane or not

Permeant - Answer-substance can pass through

Cellular differentiation - Answer-cells become specialized
-different cell types (muscle/nerve) access information encoded in different genes to
make specific proteins
-proteins that cells make determine the function

Cell membrane mechanisms - Answer--determines which substances enter a cell and
which cannot
-allow cells to respond to certain signals

, Cell to cell communication - Answer-membrane receptors / feedback loops

Feedback loops - Answer--negative or positive
-cells signal each other when the internal environment has been compromised so
adjustments can be made to keep homeostasis
-when adjustments have been made, they also signal to show the adjustments are no
longer needed.

Homeostatic Mechanisms = - Answer-feedback loops
-receptors
-control center
-effectors

Balance within the body - Answer-must replace substances that are lost and eliminate
substances that are no longer needed or in excess

Energy processes - Answer--everything in the body requires energy
-heat energy (cells kept chemically active)
-energy released from chemical reactions in a form that cells can use.

Characteristics of life - Answer--movement
-responsiveness
-growth
-reproduction
-respiration
-digestion
-absorption
-circulation
-assimilation
-excretion

Metabolism - Answer-collection of chemical reactions in cells that support life
-reproduction (digesting/ingesting/absorbing)
-respiration for growth and repair

Requirements of organisms - Answer--water
-food
-oxygen
-heat
-pressure

Homeostasis - Answer-the body's ability to keep its internal conditions stable
-all cells make a contribution
-internal environment stays relatively constant
requires most of our metabolic energy
