BIO 210 LECTURE EXAM 1
Gross Anatomy - answersexamine structures that can be seen with unaided eye
structural organization of the human body: - answerschemical (atoms), cellular (cells),
tissue (tissue), organ (organs), organ system (systems within organs), organism (human
body)
dorsal body cavity - answerslargely located on the posterior side of the body; divided
into two cavities called cranial and vertebral
(brain and spinal cord)
ventral body cavity - answerslocated on the anterior side of the body and separated into
two divisions by diaphragm; the two divisions are thoracic cavity (heart & lungs:
mediastinum contains heart, esophagus, and trachea) & abdomen cavity (pelvic)
serous membrane - answersmembrane that lines a cavity without an opening to the
outside of the body (sterile).slippery fluid that produces friction for heart beat, breathing,
and intestine movementparietal- outer layer attached to other organs or body
wallvisceral- covers internal organs
histology - answersstudy of tissues
Midsaggital - answersdivide body part into equal left and right sections
cavity - answersany fluid-filled space within the body; axle region of body is divided into
several of these; these protect internal organs and allow them to move and expand as
necessary to perform their function
Homeostasis - answersmaintenance of internal environment such as temperature and
chemical composition of blood and other body fluids (if uncorrected death & disease can
occur)
, 11 organ systems of the body - answersintegumentary, skeletal, muscular, nervous,
endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, reproductive
supine - answerslying on the back
prone - answerslying face down
feedback mechanism - answersregulation system in a living body that works to return
the body to its normal internal state
cells - answersBasic unit of life; unit that can carry out functions of life; all organisms are
composed of these
metabolism - answerssubstance within unique molecular composition; produced by
chemical reactions; this process builds up or breaks down substances depending on
needs of organisms
which characteristic of life is sometimes called "irritability"? - answersresponsiveness
organ - answersseveral types of tissue working together
Mediastinum - answersrefers to the smaller cavity within the thoracic
which layer of the pleura sits right on the lungs? - answersvisceral
Which subatomic particle has a negative charge? - answerselectron
Which subatomic particle has a positive charge? - answersproton
which subatomic particle has no charge? - answersneutron
valence shell - answersoutermost electron shell of an atom
isotope - answerstwo atoms that have the same number of protons but different number
of neutrons
two atoms of the same number of protons and different numbers of neutrons are: -
answersthe same element
two atoms with the same number of protons are always the same element -
answerstrue
the noble gases are chemically ______________ because they have a full outer
valence shell and do not react to make bonds with other atoms - answersinert/stable
(group 18 on periodic table)
