WITH BEST SOLUTIONS
Anatomy - answersThe study of body structure
Physiology - answersThe study of body function
Histology - answersstudy of tissues
Homeostasis - answersa state of body equilibrium or stable internal environment of the
body
Metabolism - answersthe sum total of the chemical reactions that occur in the body cells
Anabolism - answersenergy-requiring building phase of metabolism in which simpler
substances are combined to form more complex substances
Catabolism - answersProcess in which living cells break down substances into simpler
substances
Chemistry - answersStudies the elements and how their atoms interact to form
molecules
Bio chemistry - answersstudy of chemical composition and reactions of living matter
negative feedback - answersthe output shuts off the original effect of the stimulus or
reduces its intensity
positive feedback - answersThe results or response enhances the originals stimulus so
that the response is accelerated
Stimulus - answersproduces change in variable
Receptor - answersdetects change
Input - answersinformation sent along afferent pathway to control center
output - answersinformation sent along efferent pathway to effector
, Response - answersof effector feeds back to reduce the effect of stimulus and returns
variable to homeostatic level
Homeostasis steps - answersstimulus, receptor, input, output, response
division of ventral cavity - answers1. thoracic cavity (ribs and muscles of chest)
2. abdominopelvic cavity ( spleen, stomach, intestines, liver)
Structural Organization of the Body - answersatoms, molecules, organelle, cells,
tissues, organs, organ systems, organism
Proton - answersA subatomic particle that has a positive charge and that is found in the
nucleus of an atom
Neutron - answersuncharged subatomic particle in the atomic nucleus
Electron - answersa negatively charged subatomic particle
Atom - answersSmallest particle of an elemental substance that exhibits the properties
of that element
Molecule - answerstwo or more atoms held together by chemical bonds
Organelle - answerssmall structures that exist within cells and carry out cellular
functions
Cell - answersThe basic unit of structure and function in living things
Tissue - answersA group of similar cells that perform the same function.
Organ - answersa part of the body formed of two or more tissues that performs a
specialized function
Organ system - answersA group of organs that work together in performing vital body
functions.
Organism - answersa living thing that has (or can develop) the ability to act or function
independently
Homeostasis and Negative Feedback - answersProcess where the body detects
changes to its internal environment, activates mechanisms and makes changes to
maintain a relatively stable internal environment
Superior - answerstoward the head
