Human Physiology Exam #1 exam with
correct answers latest
Physiology is the study of ... - correct answer-the normal functioning of a living organism and it's
component parts. Greek for "relationship to nature" and studies the functions
homeostasis - correct answer-balance/euilibrium of an internal enviornment even when the external
environment is out of balance
Pathology - correct answer-occurs when normal function is disrupted and a disease state or condidtion
forces the internal environment out of balance
basic cell composition - correct answer-H2O, electrolytes, protein, lipids, and carbohydrates
subatomic particles - correct answer-electrons, protons, neutrons
Atom - correct answer-combination of subatomic particles
molecules - correct answer-a binding together of multiple atoms
Isotope - correct answer-the number of protons is consistent, but the number of neutrons may vary
Elements - correct answer-The simplest substances; they cannot be decomposed or resolved by
chemical change into simpler substances. they are the basic substances out of which all matter is
composed
Major Elements of the human body (99.9%) : - correct answer-oxygen, hydrogen, calcium, potassium,
chlorine, magnesium, carbon, nitrogen, phosphorus, sulfur and sodium
, Trace elements (.1%): - correct answer-Cobalt, fluorine, Iron, zinc, copper, iodine, manganese
Ion - correct answer-When an atom gains or loses one or more electrons and it acquires an electrical
charge. If it gains an electron (a negative charge) it is called an anion. If it loses and electron ( a positive
charge) it is called a cation
Molecule - correct answer-when two or more atoms are combined of the same kind
Compound - correct answer-when two or more atoms are combined of the a different kind
Role of electrons - correct answer-instrumental in bond formation
Ionic bonds - correct answer-formed between oppositely charged particles (NaCl) if separated in
solution the result can be an Electrolyte (fluid regulators), salt
Covalent bonds - correct answer-molecules in which electrons are shared instead instead of gained or
lost
Hydrogen bonds - correct answer-weak bonds formed between water molecules and intramolecular
bonds-bonds that hold different parts of the same molecule together into a three-dimensional shape
Polar molecules - correct answer-molecules that develop regions of partial positive and negative charge
(water)
Nonpolar molecules - correct answer-have elctrons distributed so evenly that there are no regions of
partial positive or negative charge
Water (H2O) - correct answer-universal solvent, can dissolve many differnt substances in large amounts
Hydro - correct answer-water
