APHY 164 FINAL REVIEW EXAM QUESTIONS AND
ANSWERS 100% CORRECT
Pleural Cavity - ANSWER---contains the lungs
pericardial cavity - ANSWER---contains the heart
Mediastinum - ANSWER---Centrally located space between the lungs
Diaphragm - ANSWER---a dome-shaped, muscular partition separating the thorax
from the abdomen in mammals. It plays a major role in breathing, as its contraction
increases the volume of the thorax and so inflates the lungs.
abdominal cavity - ANSWER---Contains stomach, intestines, spleen, and liver, and
other organs
pelvic cavity - ANSWER---contains urinary bladder, portions of large intestine,
and internal organs of reproduction
cranial cavity - ANSWER---contains the brain
Vertebral Cavity (Spinal Cavity) - ANSWER---contains the spinal cord
Posterior (dorsal) body cavities - ANSWER---cranial and vertebral
Ventral (anterior) body cavities - ANSWER---thoracic, abdominal, pelvic
abdominopelvic cavity - ANSWER---both the pelvic and abdominal cavities
,APHY 164 FINAL REVIEW EXAM QUESTIONS AND
ANSWERS 100% CORRECT
Isotopes - ANSWER---Different forms of an element that have the same number of
protons but a different number of neutrons.
Atom - ANSWER---smallest unit of an element
Atomic mass - ANSWER---number of protons and nuetrons
Atomic number - ANSWER---number of protons
Nucleus - ANSWER---where protons (+) and neutrons (neutral) are located
Electrons - ANSWER---located outside the nucleus and have a negative charge.
Covalent Bond - ANSWER---atoms that share electrons and are the strongest type
of chemical bond.
Nonpolar - ANSWER---covalent bond where electrons are equally shared between
the elements
Polar - ANSWER---covalent bond where electrons are unequally shared between
the elements in the bond
Ionic bonds - ANSWER---formed by atoms that transfer electrons and the resulting
positive and negative energies are attracted to form an ionic compound
, APHY 164 FINAL REVIEW EXAM QUESTIONS AND
ANSWERS 100% CORRECT
Ions - ANSWER---atoms that have gained or lost one or more electrons
Hydrogen bond - ANSWER---when a hydrogen is bonded to an electronegative
atom it becomes slightly positive and is attacted to another electronegative atom
(weak)
blood - ANSWER---liquid connective tissue, chief means of transport within the
body
plasma - ANSWER---the liquid matrix found in blood vessels. composed of water
and dissolved substances (ex. plasma proteins, electrolytes, nutrients, gases,
regulatory substances and waste products)
formed elements - ANSWER---RBCs, WBCs, and platelets
erythrocytes - ANSWER---red blood cells (RBC); no nucleus, contain hemoglobin
which carries oxygen
erythropoiesis - ANSWER---production of red blood cells
hematocrit - ANSWER---red blood cell volume, usually about 45%
anemia - ANSWER---a condition in which the oxygen-carrying capacity of blood
is reduced; characterized by reduced numbers of RBCs or a low amount of
hemoglobin
