on the venus side of the capillary, hydrostatic pressure is _______ than osmotic
pressure and there is net _____ - ✔️✔️less, resabsorption
Carbon monoxide poisoning: - ✔️✔️may stimulate EPO production
A lower than normal p50 value on the hemoglobin oxygen may be the result of -

which layer of blood contains endothelial cells - ✔️✔️tunica interna
what decreases the radius of blood vessels - ✔️✔️thromboxane
increased cardiac output is characterized by all of the following except - ✔️✔️increased
acetylcholine release
Genetic mutations in the alpha chain of hemoglobin may cause - ✔️✔️neither
thalassemia or pernicious anemia
the law of LaPlace explains that - ✔️✔️tension is proportional to blood vessel radius
small vessels are likely to collapse
large vessels are more likely to rupture
what effect does epinephrine have on action potential - ✔️✔️increase calcium influx
which of the following will cause an increase in blood flow through a systemic arteriole -
✔️✔️change in pH
on average, the lease abundant leukocytes are - ✔️✔️basophils
what will TTX do to membrane potential of conducting and contractile cells of the heart -
✔️✔️prevent action potential formation in ventricle contractile myocytes
, which of the following increases end diastolic volume - ✔️✔️stimulating the cardiac
nerve
the foramen ovale: - ✔️✔️decreases the amount of blood that travels to the right
ventricle
