15
you (are/are not) allowed to take chemicals and equipment out of the laboratory
are not
_ are appropriate to wear when working with chemicals or preserved specimens
gloves, goggles, pants, tennis shoes, lab coat
_feet is the correct distance you would be evacuated away from the Science building?
150
_ stimulates breast development and maintains lactation
prolactin
calcitonin _ blood calcium levels; parathyroid hormone _ blood calcium levels
decreases; increases
_ stimulates uterine contractions and causes milk ejection in breasts
oxytocin
thyroid hormone consists of two hormones: _ and _
thyroxine; triiodothyronine
_ and its hormones are involved in T-lymphocyte maturation in immune system
thymus
_ is the portion of the adrenal gland the initiates the fight or flight response
medulla
_ are chemical messengers released directly into the blood to inhibit/stimulate target organs
hormones
adrenal gland is divided into 2 portions: the outer portion is the _ and the inner/middle portion being the_
adrenal cortex; adrenal medulla
_ is the percentage of RBCs present in a given volume.
hematocrit
blood consists of _ and _
plasma; formed elements
_% of blood is plasma and _% is formed elements
55; 45
_ is present in the granules of a basophil
histamine
_ indirectly give rise to antibodies
B-lymphocytes
Erythrocytes function in gas transport with the use of the protein, _
hemoglobin (HgB)
_ is the condition in which the blood exhibits a low oxygen-carrying capacity
anemia
Rh factor is based on the presence of _
D antigen
blood type A can donate to blood types _ and _
A; AB
blood type B would have _ antibody
anti-a
the standard definition of an artery = arteries carry blood _ from heart
away
_ prevent backflow of blood
AV/semilunar valves
in pulmonary circulation, veins carry oxygen-_ blood
rich
the two chambers that pump blood out of the heart are called the right and left _
ventricles
an abnormal heart sound that indicates a heart valve problem is called a _
heart murmur
_ are the alternating pressure surges in an artery that occur when the heart contracts then relaxes
pulses
the auscultation sounds of the heart are _
lub dup
the QRS complex represents _ and _
ventricular depolarization; atrial repolarization
_ node is considered the pacemaker of the heart because it starts the impulse to contraction
sinoatrial (SA)
the _ artery has the greatest amplitude of all the superficial pulse points
carotid
B lymphocytes differentiate in _
bone marrow
blood pressure is usually measured in _
arteries
_ function in exchange of gases, nutrients, and wastes
capillaries
the largest artery of the body is the _
aorta
_ drains lymph from the lower right side of the body and all of the left side of the body
thoracic duct
_ is the condition in which the blood’s oxygen-carrying capacity is too low to support normal metabolism
anemia
_ is an abnormal excess of RBCs that increases blood viscosity
polycythemia
_ is the abnormally low white blood cell count/ below 4000 cells per mmᶟ
leukopenia
_ is increased WBCs, over 11,000 cells per microliter, is a normal homeostatic response to an infection in the body
leukocytosis
_ is overproduction of abnormal WBCs, accompanied by a reduction in the number of RBCs and platelets
leukemia
_ is abnormal hemoglobin, results from a change in one of the 146 amino acids in a beta chain of the globin molecule
sickle cell anemia
_ is inadequate intake of iron-containing foods or impaired iron absorption (iron is a part of hemoglobin)
iron-deficiency anemia
_ = blood clotting
coagulation
_ is the centrifugal force packs down heavier formed elements in a capillary tube, and less dense plasma remains at the top
centrifuging
_ is one complete heartbeat (atria and ventricles contract and relax)
cardiac cycle`
