legs
What is the space between the structure of a blood vessel?
Artery
Lumen
Gap
Loomen
I have muscular walls, and a small lumen.
Artery
Vein
Capillary
Arteriole
I have a large lumen, I have thin muscular walls.
Artery
Vein
Capillary
Arteriole
The ________ is composed of circularly arranged layers of smooth muscle cells
tunica interna
tunica media
tunica externa
none of the above
In arteries, the thickest layer of the wall is the
tunica interna
tunica externa
tunica media
vasa vasorum
As an arterial pathway moves farther from the heart, the arteries
get smaller
get larger
do not change in size

As a venous pathway moves closer to the heart, the veins
get smaller
get larger
do not change in size

Valves in veins
make the use of a skeletal muscle pump unnecessary for venous blood flow
are the leading cause of high blood pressure.

The atrioventricular valves are large valves that...
prevent backflow of blood from ventricles to atria
prevent backflow of blood from to atria to ventricles
prevent backflow of blood from the pulmonary artery to ventricles
prevent backflow of blood from the aorta to ventricles
The semilunar valves...
prevent back-flow of blood from ventricles to atria
prevent back-flow of blood from to atria to ventricles
prevent back-flow of blood from the pulmonary artery to ventricles
prevent back-flow of blood from the aorta to ventricles
The coronary arteries carry....
blood from the heart to the lungs
blood from the lungs to the heart
blood to the heart muscles
blood to the body from the heart
Which is the correct sequence for deoxygenated blood returning to the heart from the body?
vena cava → right atrium → right av valve → right ventricle → pulmonary semilunar valve → pulmonary artery → lungs
vena cava → left atrium → left av valve → left ventricle → pulmonary semilunar valve → pulmonary vein → lungs
pulmonary artery → right atrium → right av valve → right ventricle → pulmonary semilunar valve → pulmonary vein → lungs
pulmonary vein → left atrium → left av valve → left ventricle → aortic semilunar valve → aorta → lungs
