5. 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 phyisologist observed that ants were attracted in large numbers to the kennel of the dogs lacking a pancreas. Beacuse 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
6. 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.
7. 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
8. 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
9. Define the term feedback mechanism.
Use the table at the right and your knowledge of the living environment
to answer
questions 10 through 12 which follow.
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.
| 10. 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
11. The information in the table indicates that individual A produces enough (1.) FSH (2.) growth hormone (3.) insulin (4.) testosterone 12. 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

13. 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
14. 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
| 15. Which row in the chart contains the words that best complete this statement? The I glands produce II , which are transported by the III system. (1.) A (2.) B (3..) C (4.) D |  |
Complete each of the following statements which follow.
1. The hormone _______________ helps to stimulate the development of
female secondary sex characteristics. This hormone is produced
by the ovaries
in the female.
2. The hormone _______________ is called the "fight or flight" hormone.
3. The hormone _______________ maintains the thickness of the uterus lining in preparation for a possible pregnancy.
4. 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.
5. The major secretions of the endocrine glands are called _______________.
6. The hormone _______________ helps to stimulate the development of secondary sex characteristics in the male.
7. The condition _______________ results usually from an inability to regulate blood glucose levels properly. (Usually the blood glucose tend to become too high.)
8. _______________ are all the ductless glands.
Free-Response Section
1. List one pancreatic hormones.

4. List at least three physiological effects on the body caused by an
increased
secretion of adrenalin.
5. List two effects of the hormone estrogen.
6. Identify the structures which must be found on the surface of target

1. insulin (other student answers may be acceptable)
2. Both maintain homeostasis and release chemicals.
Other student answers may be acceptable.
3. The nervous system is faster but its effects are
of lesser duration than the endocrine system.
The nervous system releases neurotransmitters,
but the endocrine system releases hormones.

rate. It also stimulates the release
of glucose into the blood.
