Accurate Answers
Define anatomy and physiology, and explain how they're related - CORRECT
ANSWER-Anatomy-The study of the shape and structure of the body and its parts, and
their relationship to each other
Physiology-The study of how the body and its parts work or function
The relationship between anatomy and physiology are that they will always correlate
with each other anatomy being the study of the actual physical organs and their
structure as well as their relationship to each other. While physiology studies how those
organs work to function the whole body as organ systems.
List and describe the major characteristics of life - CORRECT ANSWER-1)Cell &
Organization-Example each cell can only perform the job associated with its specific
function such as heart cells, brain cells etc.
2)Energy use and metabolism-To maintain their internal order, energy is needed by
organisms. Energy is utilized in chemical reactions
3)Response to environmental changes-
responds to stimuli
4)Regulation and homeostasis-internal regulation of our body to maintain a stable
environment
5)Growth and development-all living things get larger and more complex throughout the
organism's life
6)Reproduction
7)Biological evolution-the change over time of living organisms
List and describe the major requirements of life
1)Water
2)Food
, 3)Oxygen
4)Heat
5)Pressure - CORRECT ANSWER-1)Water-A substance needed for metabolic
processes as a medium for metabolic reactions to transport substances to regulate the
body
2)Food-Needed to supply energy and for the regulation of important reactions
3)Oxygen-Needed to help release energy from food substances
4)Heat-Needed to regulate the rate of metabolic processes
5)Pressure-Needed for breathing and circulation
Define homeostasis and explain its importance to survival - CORRECT ANSWER-
homeostasis-ability to maintain relatively stable internal conditions even though the
outside world changes continuously
Homeostasis is important so that our body is able to keep a dynamic state of equilibrium
Describe a homeostasis mechanism - CORRECT ANSWER-Regulatory processes that
cells depend on, keeps the environment dominated by water (ECF), precisely
regulated(both chemical and physical elements), regardless of external influences
ex:Temperature uses hypothalamus and muscles, heat production through shivering,
heat loss through vasodilation and sweating
Explain the levels of organization of the human body - CORRECT ANSWER-1.
chemical level;includes atoms organized into molecules
2. cellular level;Molecules combine to form Muscle cells, nerve cells, and epithelial cells
3. tissue level;Tissues are groups of cells and the material sourounding them that work
together to perform funtions
