chapter 1 terms Flashcards
(30 cards)
the smallest units of an organism that carry out all the basic functions of life.
cells
structure that senses changes in the body .
receptor
study of different species to learn about body functions.
comparative physiology
cell or organ that carries out the final corrective action to restore homeostasis.
effector
control center that processes the sensory information, and directs the response.
integrating control center
a difference in chemical concentration, charge, temperature, or pressure between two points.
gradient
invented the compound microscope. he also coined the term “cells”
robert hooke
feeling a structure with the hands
palpation
listening to natural sounds made by the body such as the heart and lung sounds
ausculation
carefully cutting and separating tissues to reveal their relationships.
dissection
study of multiple species to learn about form, function, and evolution.
comparative anatomy
cutting and separating human body tissues to reveal tissue relationships.
cadaver dissection
physiology of the nervous system.
neurophysiology
11
how many organ systems does the body have?
view detail under an electron microscope.
ultrastructure
microscopic structures in a cell that carry out its individual functions.
organelles
microscopic examination of tissues for signs of disease.
histopathology
the ability to detect change, activate mechanisms that oppose it, and thereby maintain relatively stable internal conditions.
homeostasis
the constriction of blood vessels, which increase blood pressure.
vasoconstriction
mechanisms of disease
pathophysiology
the dilation of blood vessels, which decreases blood pressure.
vasodilation
physiology of hormones
endocrinology
examination of tissues with a microscope
histology
two or more tissue types that work together to carry out a particular function.
organ
