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 |
