structure of elastic arteries:
thick-walled, large vessels near the heart that conduct blood continuously away from the heart.
Pulse pressure is the difference between systolic and diastolic pressure.
Any condition in which blood vessels are inadequately filled and blood cannot circulate normally is called __________.
capable of undergoing vasoconstriction or vasodilation to influence blood flow and blood pressure.
During pulmonary circulation blood leaves the __________.
right ventricle and moves to the lungs.
protects and reinforces the vessel; anchors it to surrounding structures.
Reduction in the lumen diameter of a blood vessel as the smooth muscle contracts is known as __________.
Loss of vasomotor tone that results in a huge drop in peripheral resistance is known as __________.
lowest level of aortic pressure.
mean arterial pressure:
pressure that propels blood to the tissues.
Which of the following regulates blood flow at the entrance to each true capillary?
The vessel layer that has a direct role in vasoconstriction is the __________.
The only vessels that provide direct access to nearly every cell in the body are the __________.
its flat cells fit closely together to form a slick surface that minimizes friction as blood moves through.
provides a space for blood to travel through the vessel.
smallest of the vessels that lead into capillary beds.
peak of aortic pressure.
Which of the following arteries branches to form the common hepatic artery, left gastric artery, and splenic artery?
Which of the following types of blood vessels have the proportionally thickest tunica media of all vessels?
smallest vessels leading away from capillaries.
Hypertension is defined physiologically as a condition of sustained arterial pressure of __________ or higher.
140 over 90.
The major long-term mechanism of blood pressure control is provided by the __________.
smallest blood vessels with thin walls that allow exchange between blood and tissue cells.
Which of the following veins is the longest in the body?
great saphenous vein.
smaller vessels that distribute blood to specific body organs.
Which of the following acts on the kidneys and blood vessels to raise blood pressure?
Exchange of gases and nutrients occurs by diffusion between the __________.
capillaries and tissue cells.
contain valves to assist blood flow back toward heart.
Which of the layers of an artery wall is regulated by the sympathetic nervous system and many hormones?
Which of the following would experience increased blood flow during exercise?
_____ brings oxygen-rich blood from the lungs to the left atrium.
The presence of __________ stabilizes the wall of capillaries.
opposition to flow, a measure of the amount of friction blood encounters as it passes through the vessels.
gaps of unjoined membrane between tight junctions of endothelial cells in capillaries.
-Fenestrated capillaries, sinusoidal cappilaries, and continuous capillaries all contain intercellular clefts, but arterioles do not.
Fluids would be likely to leave or filter out of the capillary if __________.
net hydrostatic pressure (HP) is greater than net osmotic pressure (OP).
Which of the following is the correct sequence of layers in the vessel wall from outside to inside?
tunica externa, tunica media, tunica intima.
Cardiogenic shock is most likely to result from __________.
multiple heart attacks.
Blood flows from the lungs to the __________ via the __________.
left atrium; pulmonary veins.
blood-containing space in the center of the vessel.
the force per unit area exerted on a vessel wall by the contained blood.
__________ inhibits fibrinolysis by competing with plasminogen and may contribute to the formation of atherosclerotic plaques.
the volume of blood flowing through a vessel, an organ, or the entire circulation in a given period.
Blood flow would be increased by __________.
increasing cardiac output.
The minute-to-minute blood flow through the capillary beds is determined by the __________.
diameter of arterioles.
a source of resistance related to the thickness, or "stickiness," of the blood.
During systemic circulation, blood leaves the __________.
left ventricle and goes directly to the aorta.
A metarteriole is a vessel that __________.
is intermediate between the arteriole and the capillary bed.
smallest veins; collect blood from capillaries as it flows back toward heart.
The flow of blood from the left ventricle to the right atrium is called the __________.
Blood flows directly from __________ into capillary beds.
Blood from the brain is returned to the heart via the __________.

total blood vessel length:
a source of resistance related to the distance blood has to travel through layers of fat to reach a destination.
branches of pulmonary arteries; structurally like veins and venules, with thin walls and large lumens.
mostly circularly arranged smooth muscle cells and sheets of elastin.
Which of the following is true when comparing arteries and veins?

The hepatic portal system collects blood from the ______and then routes it to the _____.
GI tract; liver
