conditions nearly constant. The body
systems work together to maintain
this overall equilibrium known as
A.
B.
C.
D.
regularity
homeostasis
body control
system alignment
2. You need to send urine out of your
body. Which systems are involved?
A.Nervous and endocrine systems
B.Muscular and digestive systems
C. Excretory and muscular systems
D.Endocrine and excretory systems
3. Which system is considered to be
the first line of defense as part of
your body’s immune system?
A. reproductive
B. Skeletal
C. integumentary
D. nervous
4. The correct order for the levels of
organization from smallest to
largest is
A.Cell, tissue, organ, organ system
B.Cell, atom, molecule, organ,
organ system
C.Organ system, organ, tissue, cell
D.Organism, cell, tissue, organ
5.
An individual with diabetes militias
either does not produce enough
insulin or does not respond to it properly. This
means that they are unable to maintain
homeostasis of their glucose levels. The
endocrine system regulates this process by
A.
B.
C.
D.
producing thyroxin in the thyroid gland
the exchange of carbon dioxide and oxygen
Feedback inhibition control of the hormones
insulin and glucagon produced by the
pancreas
Hydrochloric acid that breaks down
carbohydrates in the stomach
6. How do the endocrine and
reproductive systems work together?
A. Ovaries and testis produce essential
hormones for sexual development and
gamete formation.
B. The urethra carries both urine and sperm
out of the body.
C. The thymus stimulates T cell development.
D. Insulin produced by the pancreas maintains
glucose levels within the bloodstream.
7. Recognizing and coordinating the body’s
response to changes in its internal and
external environment is the function of
which body system?
A.
B.
C.
D.
digestive
nervous
Immune
muscular
8.
The level of water in blood is controlled primarily by the
kidneys. The kidneys filter blood and either direct water
to be excreted as urine or to be reabsorbed into the
blood. These kidney functions are regulated by
antidiuretic hormone (ADH). In response to
dehydration, the hypothalamus stimulates the pituitary
gland to release increased levels of ADH. In response to
excess water in the blood, the pituitary releases less
ADH. Knowing that water levels in the blood are
controlled by feedback inhibition, what events related to
kidney function occur when ADH levels decrease?
A.
B.
C.
D.
Kidneys secrete diuretics into the blood
Kidneys produce more urine
Kidneys increase reabsorption of water into the blood
Kidneys produce less urine
9. The endocrine system interacts with many
other body systems. It sends messages that
signal organs in various systems to perform
actions or to stop performing certain
actions. These signals are carried by
messengers known as
A.
B.
C.
D.
Performance indicators
hormones
On/off switches
lymphocytes
10. An individual goes to the doctor because they are
not feeling well. After some blood work the
doctor informs the patient that they have
abnormal T cell numbers and that an HIV test
should be done. Which body system is being
affected?
A.
B.
C.
D.
integumentary system
immune system
reproductive system
circulatory system
