ECPI Anatomy-Physiology 1 + labOrigins of Medical science - answer1.) Started with superstition and magic
2.) Originated in Greek & Latin terminology
Scientific Method - answer"Investigating the Natural World"
Testing a Hypothesis = - answer1.) Rejecting or Accepting the hypothesis
2.) Based on results of experiment and observations
Anatomy + Physiology = ? - answerHow 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 - answerReveals commonalities among pairs of diseases
that had not been suspected based on whole-body-level observations
Chemical Organization - answer1.Atoms
2. Molecules
Subatomic Particles - answerMake up atoms
Molecules - answerWhere atoms join together
Macromolecules - answerSmall molecules join together to make larger molecules
Human Organism Organization smallest-largest - answer1. Subatomc particles
2. atoms
3. molecules
4. macromolecules
5. organelles
6. cells
7. tissues
8. organs
9. organ systems
10. organisms
,Cells - answerbasic unit
Organelles - answercarry on specific activities
e. proteins, carbohydrates, lipids, nucleic acids
tissues - answerlayers/masses of cells with special functions
Organs - answergroups of tissues with specific functions
organs systems - answergroups of organs that function close together
organisms - answerinteracting organ systems
Internal environment - answerenvironment within the body in which the cells live
Cell membrane - answerinterior and exterior cell membranes
Interior cell membrane - answerintracellular fluid
exterior cell membrane - answerextracellular fluid
homeostasis - answerthe 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 - answerdown a gradient (High to Low)
high pressure to low pressure
high concentration to low concentration
Diffusion - answerhigh concentration to low concentration (concentration gradient)
membrane permeability - answerwhat is allowed in to the membrane or not
Permeant - answersubstance can pass through
Cellular differentiation - answercells 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 - answermembrane 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 = - answerfeedback loops
-receptors
-control center
-effectors
Balance within the body - answermust 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 - answercollection 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 - answerthe 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
