| Question | Answer |
|---|---|
| study of parts and relationships to one another | structure |
| division of anatomy studying what you can see | gross anatomy |
| division of anatomy studying structures that cannot be seen with the naked eye | microscopic anatomy |
| division of anatomy studying development | developmental |
| phisiology-study of how body parts work | physiology |
| anatomical study that reduces organs to tissues and cells | reduction |
| anatomical study that studies how things work by putting them back together | synthesis |
| gross anatomy study of all structures in one part of the body | regional |
| gross anatomy study according to the system they belong to | systematic |
| gross anatomy study of internal structures as they relate to the overlying skin | surface |
| microscopic anatomy studying cells | cytology |
| microscopic study of tissues | histology |
| principle that states that function always reflects structure; what a structure can do depends on its specific form | principle of complementarity |
| _____-cells-tissues-_____-organ system-organism | chemicals, organs |
| 7 basic life function | maintain boundaries, responsiveness, growth, reproduction, differentiation, movement, metabolism |
| hypterplasia | increase in cell number |
| hypertrophy | increase in cell size |
| occurs after reproduction, how fertilized eggs become all organs/systems | differentiation |
| means of movement | locomotion, propulsion, contractility |
| sum of all the chemical reactions in the body; obraining energy and raw materials and using for life proccesses | metabolism |
| survival needs | water, nutrients, oxygen, heat, pressure |
| pressure gradients required for: | breathing, gas exchange in the lungs, blood flow |
| characteristics of water that make it essential for life | solvent, high heat capacity, high heat vaporization, lubricant |
| _____&_____systems in contact with the external environment to take in nutrients and oxygent | digestive, respiratory |
| metabolic wastes are eliminated by _____&_____systems | urinary, respiratory |
| ability to maintain a relatively stable internal environment | homeostasis |
| features of maintaining homeostasis | common cell evnironment, dynmaic state of equilibrium, stress, organ and organ systems that function to maintain stable environment |
| 3 interdependent components of chontrol mechanisms | receptor, control center, effector |
| determines that set point at whihc the variable is maintained- determines if action is needed | control center |
| feedback system in which the output shuts off origional stimulus | negative feed back |
| feedback system in which the output enhances or exaggerates the original stimulus | positive feedback |
