What is the difference between anatomy and physiology? - ANS-Anatomy is the study of the
structure of body parts, whereas physiology is the study of the function of body parts
What are the levels of organization? - ANS-subatomic particles, atom, molecule,
macromolecule, organelle, cell, tissue, organ, organ system, organism
What are the requirements of life? - ANS-Water, food, oxygen, heat, pressure
What are the characteristics of life? - ANS-Movement (internal or gross); Responsiveness
(reaction to internal or external change); Growth (increase in size without change in shape);
Reproduction (new organisms or new cells); Respiration (use of oxygen; removal of CO2);
Digestion (breakdown of food); Absorption (movement of substances through membranes and
into fluids); Circulation (movement within body fluids); Assimilation (changing nutrients into
chemically different forms); Excretion (removal of metabolic wastes)
Define homeostasis - ANS-Body's maintenance of a stable environment
What is a homeostatic mechanism? - ANS-the body maintains homeostasis through a number
of self-regulating control systems; examples are regulating body temperature and pressure
sensitive receptors to regulate body pressure
Define matter - ANS-Anything that takes up space and has mass (weight). It is composed of
elements.
Define element - ANS-fundamental substance composed of chemically identical atoms
Define atoms - ANS-smallest particle of an element; basic unit of matter
What is the structure of an atom? - ANS-An atom consists of a nucleus containing protons and

, Neutron - ANS-subatomic particle that has no charge
Electron - ANS-subatomic particle that has a negative charge
Atomic number - ANS-number or protons in nucleus
Atomic mass - ANS-number of protons plus number of neutrons
What are covalent bonds? - ANS-Covalent bonds are formed when atoms share electrons to
become stable with filled
outer shells
What are ionic bonds? - ANS-2 oppositely charged atoms form this bond when electrons are
transferred from one atom to another atom
What are hydrogen bonds? - ANS-Weak attraction between positive end of one polar molecule
and negative end of another polar molecule; formed between water molecules
Define ion - ANS-When atoms gain or lose electrons, they become ions.
Define synthesis reaction - ANS-Two or more atoms or molecules are joined together
Define decomposition reaction - ANS-Larger molecules are broken down into smaller ones
Define exchange reaction - ANS-Parts of molecules trade places
Define reactant - ANS-The starting materials of the reaction - the atoms, ions, or molecules
Define product - ANS-Substances formed at the end of the chemical reaction
Define catalyst - ANS-influence the rates of chemical reactions
What is an acid? - ANS-Electrolytes that release hydrogen ions in water
What is a base? - ANS-Electrolytes that release ions that combine with hydrogen ions in water
What is a salt? - ANS-Acids and bases that react to form water and electrolytes
What is a pH scale? - ANS-represents the concentration of hydrogen ions [H+] in solution
Neutral solution - ANS-pH 7;
indicates equal concentrations of H+
and OH-
