26
What hormones are produced by the pancreas?
Insulin and glucagon
27
What hormones are produced by the adrenal glands?
Estrogen, progesterone, steroids, cortisol, cortisone
28
Links nervous system to endocrine system via the pituitary gland.
Hypothalamus
29
Maintains metabolic processes.
Thyroid gland
30
Regulates blood calcium levels.
Parathyroid gland
31
Keeps biorhythm.
Pineal gland
32
Controls blood sugar levels and helps digest food.
Pancreas
33
Elicits a fight or flight response.
Adrenal glands
34
Posterior pituitary gland produces __________ __________ which regulates blood molarity.
Antidiuretic hormone (ADH)
35
__________ __________ __________ produces antidiuretic hormone which regulates blood molarity.
Posterior pituitary gland
36
Normally, blood osmolarity is:
300mOsm/L
37
ADH __________ water permeability in the nephron.
Increases
38
ADH increases water permeability in the nephron. This leads to:
More water reabsorption
39
If normal blood osmolarity increases, osmoreceptors in the __________ trigger the release of ADH from the posterior pituitary gland.
Hypothalamus
40
The __________ __________ __________ is a master gland that produces many hormones.
Anterior pituitary gland
41
The anterior pituitary gland specifically produces many __________ __________.
Tropic hormones
42
Tropic hormones regulate the function of:
Endocrine cells or glands
43
__________ __________ is one the the hormones produced by anterior pituitary gland.
Growth hormone
44
A benign tumor of the pituitary gland can cause continuous and excessive growth hormone production, which results in a condition known as:
Acromegaly
45
The __________ __________ produces hormones to stimulate and maintain metabolic processes.
Thyroid gland
46
Too little thyroid function can result in:
Weight gain, lethargy, and intolerance to cold
47
Too much thyroid function can result in:
High body temperature, sweating, weight loss, irritability, and high blood pressure
48
Bulging eyes and goiters are characteristic of:
Graves' diseases
49
The __________ __________ produces hormones to regulate blood calcium level.
Parathyroid gland
50
If blood calcium level falls below normal range, PTH stimulates calcium uptake in __________ of the excretory system and __________ in the digestive system.
Kidneys, intestines
51
If blood calcium level falls below normal range, PTH stimulates calcium calcium release from __________.
Bone *this is important for bone growth
52
The pancreas produces hormones that regulate blood __________ levels.
Glucose
53
Lowers blood glucose levels.
Insulin
54
Insulin is produced from __________ cells.
Beta
55
Increases blood glucose levels.
Glucagon
56
Glucagon is produced from __________ cells.
Alpha
57
Insulin and glucagon are both __________ and __________ hormones.
Water-soluble, polypeptide
58
___________ is the deficiency of insulin or decreased response to insulin in target tissues.
Diabetes
59
Insulin-dependent diabetes. Autoimmune disorder (immune system destroys beta cells of the pancreas).
Type 1 diabetes
60
Non insulin-dependent diabetes. Target cells fail to take up glucose from blood, resulting in general insulin deficiency.
Type 2 diabetes
61
Adrenal glands produces hormones in response to __________.
Stress
62
For short term stress, adrenal glands produce __________ and __________.
Epinephrine and norepinephrine
63
For long term stress, adrenal glands produce __________ and __________.
Mineralocorticoids and glucocorticoids
64
During fight-or-flight response, what in our bodies increases?
Blood glucose, blood pressure, and metabolic rate
65
During fight-or-flight, what changes?
