Orientation to the Human Body

sensory nerve that sends information about the body and its environment to the brain

the study of the structure and form of an organism

process of listening to sounds that the body produces, usually with the aid of a stethoscope, in order to gain information about the body

nerve that carries information from the brain to the rest of the body

the process of ridding the body of metabolic waste products

molecular framework secreted by cells that supports them structurally and biochemically

the study of an organism's tissue structure under a microscope

the body's processes to physiologically regulate its internal environment with response to fluctuations that occur in the internal or external environment

control center that integrates information received from receptors to determine an appropriate response or set point

on a molecular level, the biological processes that build or break molecules; on an organismal level, all of the chemical reactions within an organism that provide cells with the capacity to acquire energy and use that energy to carry out different functions

homeostatic feedback system that counteracts a stimulus by inhibiting the direction of the stimulus

structure, formed from more than one tissue, with a specific function

group of organs with a common function

the study of the function of organs and organ systems under both normal and altered conditions

homeostatic feedback system that maintains a stimulus, often increasing the action of a stimulus

protein to which signaling molecules can bind to elicit a physiological response

value where the physiological state of the body is stable

change in the internal or external environment contributing to fluctuations that occur away from the set point

the regulation of a body's internal temperature

specialized cells that are grouped together to perform a common function

the constriction, or narrowing, of blood vessels

the dilation, or widening, of blood vessels
