Chpt 1 Flashcards
Anatomy
Study of the structures of the body
Homeostasis
Relatively constant internal environment
Positive feedback loops
An initial stimulus produces a response that enhances the change in original condition to make it ends faster
Negative feedback loops
A variation outside the desired range causes the body to respond to end the variation
Physiology
The study of how organs perform their functions
Root language for medical terminology
Latin
Eponyms
Things named after discoverers or victims
Parkinson’s
Macroscopic anatomy
Examines large structures of the body
Microscopic anatomy
Deals with structures that cannot be seen without magnification
Cytology
Study of cells
Histology
Study of tissues
Levels of organization
- atoms
- molecule
- macromolecule
- organelle
- cell
- tissue
- organ
- organ system
- organism
Intrinsic regulation
Self regulation by a cell or organ automatically
Extrinsic regulation
Regulation by the endocrine or nervous system
Homeostatic regulation mechanism parts
- receptor
- control/integration center
- effector
Receptor
Receives info that something is off
Control/integration center
Receives and processes info
Effector
Cell or organ hat responds to commands or control center
Equilibrium
When opposing forces are in balance
Dynamic equilibrium
Systems are constantly adjusting and adapting to changing conditions

* skin, hair, nails, sweat, oil glands
Respiratory system organs
•nose, pharynx, larynx, trachea, bronchi, bronchioles, lungs
Digestive system organs and functions
- converts food into usable molecules, absorbs food, eliminates waste
- mouth, pharynx, esophagus, stomach, intestines, rectum
Muscular system functions and organs
- movement, circulate blood, move food through body
* types of muscles
Circulatory system functions and structures
