Bio 201 Rio Salado Exam 1 UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Explain the principle of complementarity. - CORRECT 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) - CORRECT
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) - CORRECT 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 - CORRECT 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 a painful stimulus such as a broken glass; As blood volume drops, the
hypothalamus of the brain is stimulated to release ADH to the blood.
Positive Feedback Mechanisms- The result or response enhances the original stimulus so that the
activity is accelerated. Examples: Homeostatic mechanisms are the enhancement of labor
contractions during birth and blood clotting.
Homeostatic Imbalance and Disease. - CORRECT ANSWER - Most disease can be
regarded as a result of the disturbance of homeostasis, which is known as homeostatic imbalance.
Any abnormal condition is known as homeostatic imbalance.
Anatomical Terminology - CORRECT ANSWER - Refer to page 12-18
9 Regions of Abdominopelvic Regions - CORRECT ANSWER - 1) Right Hypchondriac
Region (Top right) Organ: Liver Gallbladder
2) Right Lumbar Region (Middle Right) Organs: Ascending Colon of large intestine
3) Right Iliac (inguinal) region- Cecum
4) Epigastric Region (middle top) Organs: Stomach
5) Umbilical Region (middle middle) Organs: Small intestine and Transverse colon of large
intestine.
6) Hypogastric (pubic) region (Bottom middle) Organs: Urinary Bladder
7) Left Hypochondriac Region (Top left) Organs: Diaphragm
