Cards

Term

Definition
Skeletal system
Term
name the region that corresponds to the arm?
Definition
brachial
Term
Illustrate the properties and processes that are associated with all living things
Definition
All living organisms have the same basic functions, reponsiveness, growth and differentiation, reproduction, movement, metabolism and excretion
Term
An analysis of the body system that performs crisis management by directing rapid, short-term, and very specific responses would be involve the
Definition
Nervous system
Term
Applying the concept of planes of section, how could you divide the body so that the face remains intact
Definition
coronal section
Term
Why must large organisms have circulatory systems?
Definition
In large organisms with specialized organ system that performs absorption, respiration, and excretion in different regions of the body, there must be a means of internal transport for these products. Passive processes such as diffusion and osmosis would occur too slowly to permit the organism to function and stay alive.
Term
Explain how a disruption in the normal cellular division processes of cells within the bone marrow support the view that all levels of the organism are interdependent?
Definition
A disruption of the cellular division process within the bone marrow will result in the production of too few red blood cells (anemia) or too many red blood cells (polycythemia) within the vessels of the cardiovascular system. Anemia will affect the amount of oxygen carried to peripheral tissues, thereby affecting overall metabolism. Polycythemia will produce altered peripheral metabolism due to the "clogging" of blood vessels by the increased number of cells attempting to get through peripheral capillaries.
Term
A child born with a severe cleft palate may require surgery to repair the nasal cavity and reconstruct the roof of the mouth. Determine what body systems are affected by the cleft palate,
Definition
The body systems affected would include: digestive, respiratory, and skeletal systems.

Definition
study of internal structure of individual cells
Term
