Bio 201 Rio Salado Exam 1 complete
verified solutions + rationales (PASS
GUARANTEED)
Explain the principle of complementarity. - answer Anatomy and
physiology are inseparable because function always reflects structure
examples.) bones support and protect body organs because they
contain hard mineral deposits and, blood flows in one direction through
the heart because the heart has valves that prevent back flow.
Levels of structural organization (in order of increasing complexity) -
answer 1) Chemical Level- At this level atoms, tiny building blocks of
matter combine to form molecules such as water and proteins.
2) Cellular Level- All cells have some common functions, but individual
cells vary widely in size and shape, reflecting their unique functions in
the body.
3) Tissue Level- Tissues are groups of similar cells that have a common
function
4) Organ Level- Organs are made up of different tissues.
5) Organ (System) level- Organ systems consist of different organs that
work together closely.
6) Organismal Level- The human organism is made up of many organ
systems.
, 11 Organ systems of the body (major functions) - answer 1)
Integumentary System- Forms the external body covering.
2) Skeletal System- Protects and supports body organs.
3) Muscular System- Allows manipulation of the environment,
locomotion, and facial expressions.
4) Lymphatic System- Picks up fluid leaked from blood vessels and
returns it to the blood
5) Respiratory System- Keeps blood constantly supplied with oxygen and
removes carbon dioxide.
6) Digestive System- Breaks down food into absorbable units that enter
the blood for distribution to body cells.
7) Nervous System- Fast acting control system of the body.
8) Endocrine System- Glands secrete hormones that regulate processes
such as growth, reproduction, and nutrient use.
9)Cardiovascular System- Blood vessels transport blood, which carries
oxygen, carbon dioxide, nutrients , wastes, etc.
10) Urinary System- Eliminates nitrogenous wastes from the body.
11) Reproductive System- Overall function is production of offspring.
Negative and Positive Feedback Mechanisms - answer Negative
Feedback Mechanisms- In these systems, the output shuts off the
original stimulus or reduces intensity. Examples: Regulation of body
temperatures; Withdrawal Reflex in which the hand is jerked away from
