9891790633	anatomy	Study of the structure of an organism.	0
9891790634	physiology	Study of the functions an organism performs.	1
9891790635	tissues	Groups of cells with a common structure and function.	2
9891790636	epithelial tissue	Tissue that covers outside of the body and lines organs and cavities.	3
9891790637	mucous membrane	Membrane that secretes mucus that lubricates the surface of organs and keeps them moist.	4
9891790638	macrophages	cells that roam connective tissue and engulf foreign particles and debris of dead cells.	5
9891790639	muscle tissue	Tissue made of cells capable of contracting.	6
9891790640	nervous tissue	Tissue that senses stimuli and transmits signals.	7
9891790641	organs	A structure consisting of several tissues adapted as a group to perform specific functions.	8
9891790645	homeostasis	"Steady state" process by which organisms maintain a relatively stable internal environment	9
9891790648	negative feedback	Maintains a steady state. mechanism of homeostasis that tends to stabilize a process by reducing its rate or output	10
9891790649	positive feedback	Takes organism away from a steady state. mechanism of homeostasis feedback that tends to magnify a process or increase its output	11
9891790655	Epithelium	Layer of skin cells forming the outer and inner surfaces of the body	12
9891790656	Villi	Folds of the intestines for absorption that increase surface area	13
9891790657	intestines	tube-shaped organs through which most nutrients and water are absorbed from food	14
9891790659	endocrine system	system of glands and hormones that controls secretion of blood-borne chemical messengers (circulatory system)	15
9891790660	Nervous System	transports electrochemical signal Tragets neural, muscle, or endocrine cell response pathway: nerone axon neuron responce (pathway Matters)	16
9891790665	Hypothalamus	part the brain that regulates hunger, body temperature and other functions	17
