Anatomy Chapter 1 Body Orientation Review
Groups of cells that have a common function.
Cardiovascular System primary organs
Heart and Blood vessels
System that functions in the storage of minerals, such as calcium.
Systems that rids the body of indigestible food residue in feces.
System that removes the nitrogen-containing metabolic waste in urine.
Component of a control system that provides the means for the control center's response (output).
Body's ability to maintain stable internal conditions.
Is medial to the spine.
Divides the body into equal left and right halves.
Name a positive feedback mechanism
Blood clotting and the birth of a baby.
The study of the function of the body and it's parts.
Structural organization of body, simple to complex
atoms,cellular, tissue, organ, system, organism.
Blood cell formation, is a function of the skeletal system.
System that covers external surface of the body and protects deeper tissue like, skin, nails, hair.
Maintain boundaries, movement, responsiveness, metabolism.
Elements in a control system in correct order
stimulus, receptor, afferent pathway, control center, efferent pathway, effector, response.
Difference between afferent and afferent pathways
Afferent are pathways leading to the cortex (sensory), efferent are pathways leading away (motor). You are affected by a situation, you are effect change on someone else.
Element of a control system detects change.
Positive feedback systems
Operate in such a way that the initial stimulus is enhanced and increases.
Abdominopelvic body cavity
Can be subdivided into four quadrant and 9 regions.
Organs in the Thoracic body cavity
Lungs and heart.
Organs in the dorsal body cavity
Brain and spinal
Section that divides the body on the longitudinal plane into two equal right and left parts.
Divides the Thoracic from the Abdominalpelvic cavity.
Lowest level of structural organization
Homeostatic control mechanisms
are mostly negative feedback reactions like, sweat to lower body temp,secrete more insulin to lower bld sugar level.
Percentage of H2O in body
60% - 80%.
inferior to umbilical region.
end or upper part of structure or body; above.
Toward the backside
of the body; behind (posterior).
Away from the midline
of the body on the outside.
Away from the body surface;
Farther from the origin of a body part
or the point of attachment of a limb to the body trunk.
or at the
midline of the body
, on the inner side.
Close to the origin of the body part
or point of attachment to a limb to the body trunk.
or at the
front of the body
; in front of (anterior).
Anatomy (a-NAT-ō-mē; ana- = up; -tomy = process of cutting) is the
science of structure
and the relationships among structures.
Physiology (fiz′-ē-OL-ō-jē; physio- = nature, -logy = study of) is the
science of body
, that is, how the body parts work.
