human organism Flashcards
the basic structure and functional unit of life
cell
is a group of organs classified as a unit
organ system
composed of two or more tissue type
organ
is a group of similar cell
tissue
ability to use energy
metabolism
specific relationship of many individual
organization
ability of an organism to sense changes
responsiveness
changes an organism undergoes through time
development
change in cell structure and function
differentiation
the formation of new cell
reproduction
maintenance of a relatively constant environment within the body despite fluctuation
homeostasis
homeostasis is governed by
nervous system and endocrine system
when any deviation from the set point is made smaller or is resisted
negative feedback mechanism
when the initial stimulus further stimulates the response
positive feedback mechanism
lying face upward
supine
lying face downward
prone
above or up
superior
down or below
inferior
means nearest to the point attachment
proximal
distant from the point attachment
distal
towards the midline
medial
away from the midline
lateral
structure close to the surface of the body
superficial
towards the interior of the body
deep
runs vertically from right to left dividing the anterior and posterior of the body
frontal plane
runs vertically from right to left dividing the right and left of the body
sagittal plane
sagittal planes runs through the midline of the body
median plane
runs parallel to the surface dividing the superior and inferior of the body
transverse plane
trunk large cavities: surrounded by the rib cage
thoracic cavity
trunk large cavities: is a small space enclosed by the bones of the pelvis
pelvic cavity
trunk large cavities: bounded primarily by the abdominal muscle
abdominal cavity
line the trunk cavities and cover the organ of these cavities

c. pericardial
a. serous membrane
contains three large cavities that do not open outside of the body
