Ch 1 Flashcards
Studies the structure of body parts
Anatomy
Concerns the function of the body
Physiology
Study of large body structures visible to the naked eye
Gross anatomy
Deals with structures too small to be seen with the naked eye
Microscopic anatomy
Traces structural changes that occur throughout the life span
Developmental anatomy
Function always reflects structure(what a structure can do depends on its specific form)
Principle of complementarily of structure and function
Levels of structural organization
Atom-molecule-organelle-cell-tissue level-organ-organ system-organismal
What are the necessary life functions
Metabolism, maintain boundaries, movement
Reproduction, responsiveness
Growth, excretion, digestion
What are the survival needs
Nutrients Atmospheric pressure Normal body temp Oxygen Water
What are the organ systems
Integumentary, muscular, endocrine, nervous, skeletal, reproductive, digestive, cardiovascular, respiratory, lymphatic, urinary, reproductive
Works continuously to maintain homeostasis
Positive feedback
Once homeostasis is met, goes back down
Most widely used
Negative feedback
Dynamic state that operates in limits to attain stability
Homeostasis
Example is oxytocin(child birth) and blood clotting
Positive feedback
Example is body temperature and ADH(water balance)
Negative feedback
