6.
Known as the "master gland" this two-lobed gland releases hormones that control growth and timing process in the body:
a)
Pineal
b)
Pituitary
c)
Pancreas
d)
Thyroid
7.
The parathyroid:
a)
Secretes hormones that control metabolism
b)
Is the large butterfly-shaped gland surrounding the larynx
c)
Secretes insulin and glucagon
d)
Secretes hormones that regulate calcium (Ca+) levels
8.

Produces thymosin, which "matures" T-cells in the immune system
b)
Produces T3 and T4, both of which act to control metabolism
c)
Secretes hormones that control calcium levels

Insulin
b)
Trypsin
c)
Glucagon

Testosterone
b)
Adrenaline
c)
Human Growth Hormone
d)
Progesterone
11.
Some cells in the atria of the heart secrete hormones that:
a)
Increase calcium uptake by the kidney
b)
Decrease digestive processes
c)
Decrease blood pressure (BP)
d)
Increase heart rate
12.
Adrenalin is produced by which part of the adrenal glands?
a)
Medusa
b)
Medulla
c)
Cortex
d)
Kidney
13.
Which is an example of a NEGATIVE feedback loop
a)
Oxytocin release increases uterine contraction, which results in more oxytocin release. This cycle continues until the baby is born.
b)
Fruit are signaled to ripen by the production of ethylene gas by the plant. As they ripen, the fruit begin to produce ethylene gas, which , in turn ripens more fruit, causing the relase of more ethylene gas. Eventually all fruit are ripened.
c)
Blood pressure decreases, which causes the release of aldosterone by the adrenal glands. This hormone causes an increase in sodium levels in the blood. This increase in sodium causes fluid retention. As a result, blood pressure increases, and aldosterone release ceases
d)
Damage to a blood vessel signals platelets to become active. Active platelets release signals to nearby platelets, telling them to become active, and so on.
14.

Brain

Skin
c)
Liver
d)

Testes
c)
Thyroid
d)
Pancreas
17.
