a patient comes into the ER with sever abdominal pain. Her enterocyte sedimentation rate is tested and comes back normal. what condition would you still be concerned she is experiencing
the erythrocytes clumping together and stacking up to form a column
the antigens on red blood cells that determine a persons blood type
a patient is diagnosed with sickle cell anemia, when diagnosed their erythrocyte sedimentation rate was 0mm/h. later is was 5mm/h. has the disease improved or digressed
when ____ sickle cell hemoglobin have the same shape has normal hemoglobin
clinic problems associated with sickle cell anemia are due to one amino acid out of the ___ in the beta chain being different from normal

during infection, phagocytosis of bacteria and fungi followed by enzymatic destruction
when stimulated by bacteria or toxins, they differentiate into plasm cells which produce and secrete antigen specific antibodies
attack virus and tumors
differentiate into macrophages after phagocytosis
attack parasitic worms, lessen severity of allergic reations
release histamine/increase allergic reactions

when antibodies cross the placenta blood barrier and attack the erythrocytes of the fetus
the innermost layer of the blood vessel wall
layer of the blood vessel wall composed of smooth muscle and elastin
vessel with the largest lumen and thin tunica media
arteries with most smooth muscle but less elastin, delivers blood to specific organs
arteries which provide greatest resistance to flow
exchange of materials between the blood and tissue cells takes place in ____
blood pressure is the lowest in this vessel
Venous one-way valve
a special adaptation in veins that prevents the back flow of blood as it travels toward the heart
which type of blood vessel consists of only a thin tunica intima?
applying norepinephrine to a blood vessel would alter which source of peripheral resistance?
increasing hematocrit would alter which source of peripheral resistance?
altered by arteriosclerosis
alters vessel diameter, thus increasing vessel diameter
Stimulation of the vagus nerve
this would decrease cardiac output caused by decreased heart rate

the dicrotic notch represents the brief interruption of smooth blood flow caused by the backflow of blood that closes which valve?
the usual diastolic pressure

mean arterial pressure
"average" pressure in the arteries
when the pressure in the blood pressure cuff is greater then the artery, what sounds are heard?
the first sound you hear though the stethoscope as the pressure in the cuff is released
the correct formula for calculating mean arterial pressure
sensors in the aortic arch and carotid sinus that contain nerve endings that monitor blood pressure by the degree of stretch on the vessel wall
branch of the autonomic nervous system that is affected when a change in blood pressure increases the impulse to the cardiovascular center
