The thymus gland secretes hormones called ____ that ____ - ANS-Thymosins; control
production and differentiation of white blood cells
Exocrine glands differ from endocrine gland in that exocrine glands - ANS-Secrete
through ducts or tubes to the body's exterior
Oxytocin stimulates the kidneys to conserve water - ANS-False
The secretion of parathyroid hormone is controlled primarily by the - ANS-concentration
of blood calcium
A person under stress may have a lowered resistance to infection - ANS-True
A hormone is a ____ and the target cell is ____ - ANS-Molecule that has a metabolic
effect on another cell; a cell that has receptors for specific molecules
The ____ secretes triiodothyronine - ANS-Thyroid gland
Choose the example that does not demonstrate a negative feedback loop of hormonal
control - ANS-Pressure receptors sense the movement of a baby against and through
the cervix during labor. They stimulate the hypothalamus to release a hormone that
causes uterine contractions. This causes more pressure receptor stimulation, leading to
larger releases of the hormone and stronger, more frequent contractions. Hormone
release ceases after pressure sensation cease
A hormone is a secreted molecule that is carried in the bloodstream to where it acts on
target cells that bear specific receptor for that hormone - ANS-True
A female patient is experiencing a hormonal imbalance that is causing her to skip
menstrual periods due to low estrogen and miss ovulation. Which of the following is
most likely the imbalance hormone? - ANS-follicle-stimulating hormone
As a result of the general stress response, blood concentrations of epinephrine -
ANS-And cortisol rise
Secretion of insulin causes - ANS-A decrease in the concentration of blood glucose
,A sweat gland is an example of a(n) ____ gland - ANS-Exocrine
Maxwell has a very high metabolic rate, is skinny, and has protruding eyes. These are
symptoms of - ANS-Hyperthyroidism
Nonsteroid hormones include peptides, proteins, glycoproteins, and amines - ANS-True
Hormones that the posterior pituitary secretes are synthesized in the -
ANS-Hypothalamus
Simple goiter is most prevalent where the soil lacks - ANS-Iodine
Steroid hormones diffuse through cell membranes, then bind with receptors, whereas
nonsteroid hormones bind receptors on the target cell membrane - ANS-True
The hormone that the pineal gland secretes is - ANS-Melatonin
The sex hormones from the adrenal cortex are primarily androgens - ANS-True
The target cells of releasing hormones are in the anterior pituitary gland - ANS-True
Steroid hormones - ANS-Are soluble in lipids
The hormone that stimulates calcium decomposition into bone is - ANS-Calcitonin
A night-shift worker experiences extreme difficulty falling asleep due to being exposed
to bright lights during both night and day. The unusual pattern of light exposure is
disturbing their ____, which controls the release of the hormone ____ - ANS-circadian
rhythm; melatonin
"Endocrine" means - ANS-Internal secretion
What vessel of the lower extremity is indicated in this figure? - ANS-Deep femoral artery
In the cardiovascular system, what vessels are the site of nutrient, gas, and waste
exchange? - ANS-Capillaries
What abdominal blood vessel is indicated in the figure? - ANS-Renal artery
, A cold, pale foot could be a sign of a blockage of blood flow in the ____ artery -
ANS-Popliteal
In mitral valve prolapse, the mitral valve - ANS-Bulges into the left atrium during
ventricular contraction
The aorta is the largest artery in the pulmonary circuit - ANS-False
Venules continue from capillaries to from veins, which return blood to the atria -
ANS-True
Tim runs 5 to 8 miles a day. He has an enlarged heart and low heart rate and blood
pressure. He most likely has - ANS-A very healthy cardiovascular system
When a person's pulse is taken by palpation near the thumb on the wrist, which artery is
felt? - ANS-Radial artery
In the arterial disease atherosclerosis, - ANS-Risk of a thrombus or embolus forming
increases
The structures that contain chemoreceptors that detect blood levels of oxygen and
carbon dioxide are the - ANS-Aortic bodies
Identify the artery of the upper extremity indicated in the figure - ANS-Brachial artery
Plasma proteins in capillaries help to - ANS-Maintain the osmotic pressure of the blood
Because net inward pressure in the venular ends of capillaries is less than net outward
pressure in the arteriolar ends of capillaries - ANS-More fluid leaves the capillaries than
returns
When smooth muscles in the walls of the arteries are stimulated to contract, -
ANS-Blood pressure increases
Water and dissolved substances leave the arteriole end of a capillary due to ____, and
enter the venule end of a capillary due to ____ - ANS-Hydrostatic pressure being higher
than osmotic pressure; osmotic pressure being higher than the hydrostatic pressure
The systemic circuit - ANS-Sends oxygen-rich blood to the tissues
