BIO 201 RIO SALADO EXAM 1
QUESTIONS AND ANSWERS
(SCORED A+)
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.
Cutaneous Membrane - ANSWER-skin, organ system consisting of a keratinized
stratified squamous epithelium firmly attached to a thick layer of dense irregular
connective tissue
