Choose the best answer and write it on the blank.
___ 1. A similarity between the nervous system and
the endocrine system in humans is that
they both
1.) are composed of neurons
2.) maintain homeostasis
3.) are composed of glands
4.) secrete chemicals across synapses
Use the diagram at the right and your knowledge of
the living environment to answer questions 2 through
4.
___ 6. A physiologist removed the pancreas from
several dogs in an experiment to investigate its
function. He placed five normal dogs in one kennel
and five dogs lacking a pancreas in another kennel.
The physiologist observed that ants were attracted in
large numbers to the kennel of the dogs lacking a
pancreas. Because they lacked a pancreas, what
substance did these dogs have that attracted the ants?
1.) enzymes in their saliva
2.) sugar in their urine
3.) mineral salts in their feces
4.) oil in their fur
___ 2. A hormone
that increases the
rate and strength of
heart contractions
during times of
sudden stress is
secreted by
1.) A 2.) E
3.) F 4.) D
___ 7. Which statement best describes the chemical
substances secreted by endocrine glands?
1.) They are secreted in one place and most often act
at another.
2.) They are found only in vertebrates.
3.) They are secreted into specialized ducts for
transport.
4.) They are distributed by the nervous system.
___ 3. Hormones
that regulate the
menstrual cycle are
secreted by
1.) A and D 2.) C and E
3.) B and F
4.) F and A
___ 8. Cells within this gland secrete a hormone that,
in times of emergency, increases the glucose level of
the blood and speeds up the actions of the circulatory
and respiratory systems.
1.) hypothalamus
2.) testes
3.) adrenal
4.) pancreas
___ 4. A hormone which decreases blood sugar levels
is produced by structure
1.) A
2.) B
3.) C
4.) D
___ 9. Groups of cells within this gland secrete
hormones that maintain normal levels of simple and
complex carbohydrates in the body.
1.) adrenal
2.) pancreas
3.) hypothalamus
4.) thyroid
___ 5. Which row in the chart contains the words that
best complete this statement?
___ 10. Pituitary growth hormone can affect cells in
various parts of the human body because the
hormone is secreted directly into
1.) the digestive tract
2.) the bloodstream
3.) muscle tissue
4.) glandular ducts
The I glands produce II , which are transported by the
III system.
1.) A
2.) B
3.) C
4.) D
___ 11. A drastic change in the metabolic rate of a
human would most likely result from the
1.) oversecretion of the salivary glands
2.) deterioration of the skeletal system
3.) overproduction of auxins
4.) malfunction of the endocrine glands
Use the table at the right and your knowledge of the
living environment to answer questions 12 through
14. Individual A and individual B drank an equal
amount of glucose solution. Every half hour
for the next 4 hours, the glucose level in their blood
was measured. Normal glucose level
is 80-100 mg/100dL.
17. The hormone _______________ stimulates the
conversion of excess sugar in the blood to glycogen
which is animal starch in the liver and assists in
taking glucose into the cells. This hormone is
produced in the pancreas.
18. The major secretions of the endocrine glands are
called _______________.
19. The hormone _______________ helps to
stimulate the development of secondary sex
characteristics in the male.
20. The condition _______________ results usually
from an inability to regulate blood glucose levels
properly. (Usually the blood glucose tend to become
too high.)
21. _______________ are all the ductless glands.
___ 12. The information in the table indicates that
individual B has a condition that is most likely due to
the malfunction of
1.) testes
2.) ovaries
3.) thyroids
4.) pancreas
Free-Response Section
22. List two pancreatic hormones. [2]
___ 13. The information in the table indicates that
individual A produces enough
1.) FSH
2.) growth hormone
3.) insulin
4.) testosterone
___ 14. Based on the trends in the chart, what is the
most likely blood sugar level of individual B after 4.5
hours? (units are mg/100 dL)
1.) 150
2.) 130
3.) 100
4.) 180
Complete each of the following statements which
follow.
15. The hormone _______________ helps to
stimulate the development of female secondary sex
characteristics. This hormone is produced by the
ovaries in the female.
16. The hormone _______________ is called the
"fight or flight" hormone.
23. List at least two physiological effects on the body
caused by an increased secretion of adrenalin. [2]
