Lecture Exam 1 Flashcards
Define Anatomy
The study of the form and structure of the body
Define Physiology
The study of the function of the body
Define Metabolism
The sum of all anabolic and catabolic reactions that take place in the body
Anabolic reaction
The process by which smaller, simpler molecules are combined into larger more complex substances
Utilizes energy
Catabolic Reaction
The process by which larger more complex substances are broken down into smaller simpler molecules
releases energy
Properties common to all Organisms
Order Reproduction Growth and Development Energy processing Response to environment Regulation Evolutionary Adaptation
Property: Order
Living cells are the basis for making up a living organisms complex structure
Property: Reproduction
Organisms must reproduce offspring for the species to live
Property: Growth and Development
Inherited DNA controls organisms growth pattern
Property:Energy Processing
Organisms use food to power activities and chemical reactions
Property: Response to Environment
Uses Stimuli
Property: Regulation
Organisms regulate internal conditions (homeostasis)
Property: Evolutionary Adaptation
Adaptions over a long period of time that help an organism survive in its environment
Anatomical Position
Upright stance Feet flat on floor Upper limbs at side of body Head level Eyes forward Palms face out
Levels of Structural Organization
Chemical level Cellular level Tissue level Organ level Organ System level Organismal level
Chemical Level
Atoms
molecules
macromolecules
Cellular level
cells- the smallest living structure
Tissue level
groups of similar cells performing common functions
Organ level
2 or more tissue types performing specific functions
Organ System level
2 or more related organs working together
Axial Region
Head, Thorax, Pelvis, Abdomen (Anything that isnt an appendage
Appendicular Region
The appendages
Frontal plane
divides body into front and back
Transverse plane
divides body into cranial and caudal
Midsagittal plane
divides body symmetrically into left and right halves
sagittal plane
divides body into left and right halves
oblique plane
divides body at an angle

Define Homeostasis
Steady state of body systems that all living organisms maintain
What are feedback loops
Where the output of a circut is returned to the input
