capillaries that have a complete lining are called

continuous capillaries

after blood leaves the capillaries, it enters the


which layer of a blood vessel contains concentric sheets of smooth muscle tissue

tunica media

venae cavae are the largest of what type of vessel


a sample of tissue displays many large flattened spaces lined by fenestrated endothelium. blood moves slowly through these spaces. this tissue sample most likely came from the


exchange between a blood vessel and the cells that surround it can occur only in


which kind of vessel is also called a resistance vessel


what vessels contain elastic fibers in the walls that are stretched during systole


what vessels hold the largest percentage of the blood supply


blood moves forward through veins because of all of the following, except

pumping by the smooth muscle in the wall of the vein

which part of the vascular system functions as a blood reservoir and contains over 60% of the body's blood


the main control of peripheral resistance occurs in the


the small vessels that capillaries drain into are called


as blood travels from arteries to veins,

pressure drops

blood flow to a tissue will increase if the

arterioles dilate

blood pressure increases with all of the following, except

parasympathetic innervation

the main control of peripheral resistance occurs in the


the vascular pressure that declines from roughly 35 mm Hg to about 18 mm Hg is the

capillary hydrostatic pressure

clinically, the term blood pressure usually refers to

arterial pressure

averaged over a few heartbeats, venous return is ____ cardiac output

equal to

if blood pressure doubled, the blood flow through a vessel would be


each of the following factors would increase peripheral resistance, except


relative to the lumen, which of these vessels has the thickest tunica media


the difference between the systolic and diastolic pressures is called the ____ pressure


the blood colloid osmotic pressure mostly depends on the

concentration of plasma proteins

as blood circulates from arteries into capillaries, the total cross-sectional area of capillaries

increases and causes the blood velocity to decrease

some of the fluid that is forced out of capillaries is returned to the blood by the

lymphatic system

blood colloid osmotic pressure is produced by

large non diffusible proteins in the blood plasma

as blood travels from arteries to veins

pressure decreases

stimulation of the aortic baroreceptors reflexively results in

increased activity by the parasympathetic nervous system

during exercise

-vasodilation occurs at the active skeletal muscles
-venous return increases
-both cardiac output and stroke volume increase
-tissue perfusion to the digestive system decreases
